STRUCTURE DEFENCE

British Columbia & Alberta

Saturday, August 22, 2026

Information current as of approximately 8:30 a.m. Pacific Time.

Wildfire conditions, evacuation boundaries, road access, utilities, restrictions and fire behaviour can change quickly. Instructions from the responsible local government, First Nation, emergency authority or transportation agency always take priority.

────────────────────────────────────────

STRUCTURE DEFENCE TAKEAWAY

Here’s what we know:

The wildfire picture across southern British Columbia is beginning to change.

Bald Range remains the most consequential community wildfire and recovery operation, but the evacuation footprint has continued shrinking.

The latest RDOS statistics show that most affected properties are now under Evacuation Alert rather than Evacuation Order.

Within the District of Summerland:

• Approximately 4,580 affected properties were under Evacuation Alert.

• Approximately 530 remained under Evacuation Order.

Within the RDOS:

• Approximately 1,592 affected properties were under Evacuation Alert.

• Approximately 391 remained under Evacuation Order.

Those numbers reflect the latest available regional statistics and may change as re-entry continues.

Damage assessment has also become more precise.

In Summerland, 799 properties had been inspected in the latest official statistics:

• 42 structures were identified as destroyed.

• 7 had restricted use.

• 2 were considered unsafe.

• 9 remained inaccessible.

Within Electoral Area F, 204 properties had been inspected:

• 105 structures were identified as destroyed.

• 5 had restricted use.

• 2 were considered unsafe.

• 4 remained inaccessible.

This provides a more useful picture than the earlier preliminary estimate of approximately 150 damaged or destroyed structures.

Elsewhere:

• Pear Lake, Riley Creek and Bonanza Creek remain associated with active Evacuation Orders within the Squamish-Lillooet Regional District.

• Twin Two remains under Evacuation Alert.

• Significant road and access restrictions remain around several active wildfire environments.

• Alberta continues to show no major provincial wildfire escalation in the latest available reporting.

Here’s what we’re watching:

Today brings the first substantial weather transition after several days of heat.

Across much of the southern Interior, temperatures are falling while winds increase and showers or thunderstorms develop.

Summerland is forecast around 30°C today, with north wind potentially gusting near 50 km/h and showers or thunderstorms possible.

Lillooet is forecast around 30°C, with south winds increasing and gusts potentially approaching 70 km/h.

Boston Bar is also forecast around 30°C, with south winds potentially gusting near 70 km/h and showers or thunderstorms later today and tonight.

Rainfall could provide meaningful suppression benefit.

But the timing matters.

If strong winds arrive before sustained wetting, active fires may temporarily become more energetic or change direction before conditions improve.

Here’s why it matters:

We are moving into a different phase of this wildfire period.

The dominant story is no longer simply rapid evacuation expansion.

It is now a combination of:

• Active wildfire suppression

• Re-entry

• Infrastructure restoration

• Property damage assessment

• Transportation recovery

• Continued fire-weather risk

That is progress.

But it is not the same as wildfire season being over.

────────────────────────────────────────

TODAY'S CONDITIONS

BALD RANGE — SUMMERLAND AND RDOS

Here’s what we know:

Bald Range remains an active wildfire and recovery operation.

The most significant current information is the continuing reduction in evacuation pressure.

On Friday, another property at 23000 Gallaugher Street in Electoral Area F was downgraded from Evacuation Order to Evacuation Alert.

Most affected Summerland properties are now under Alert rather than Order.

The latest official regional statistics show:

SUMMERLAND

• 5,110 affected properties

• Approximately 4,580 under Alert

• Approximately 530 under Order

RDOS

• 1,983 affected properties

• Approximately 1,592 under Alert

• Approximately 391 under Order

Those figures reflect the latest available statistical update and should not be interpreted as a live property count this morning.

Re-entry continues neighbourhood by neighbourhood.

Highway 97 remains open through Summerland in both directions.

Wildfire-response and utility crews continue working throughout the affected area.

The Bald Range incident command structure is also increasingly shifting away from the urban Summerland environment toward areas where active fire continues farther west.

Here’s what we’re watching:

• Remaining Summerland and RDOS Evacuation Orders

• Further re-entry

• Active fire on western portions of Bald Range

• Utility restoration

• Drinking-water status

• Danger trees

• Road and slope hazards

• Today’s stronger winds

• Rainfall coverage

• Thunderstorm activity

Here’s why it matters:

The reduction in evacuation Orders is genuine progress.

But a property remaining under Order at this stage usually reflects a specific operational reason.

That could include active fire, damaged utilities, unsafe roads, danger trees, structural damage or limited emergency access.

Residents should rely on the current address-level evacuation map rather than general community status.

────────────────────────────────────────

BALD RANGE — DAMAGE ASSESSMENT

Here’s what we know:

Damage assessment is becoming more detailed.

The latest RDOS statistics provide property-level inspection results rather than only a broad preliminary estimate.

DISTRICT OF SUMMERLAND

799 properties inspected:

• 42 destroyed

• 7 restricted use

• 2 unsafe

• 9 inaccessible

• 26 empty lots

ELECTORAL AREA F

204 properties inspected:

• 105 destroyed

• 5 restricted use

• 2 unsafe

• 4 inaccessible

• 12 empty lots

These assessments may continue changing as additional properties are accessed and inspected.

Here’s what we’re watching:

• Additional inspections

• Changes from inaccessible to assessed

• Structural safety classifications

• Utility restoration to damaged neighbourhoods

• Access for property owners

Here’s why it matters:

A single regional “structure loss” number can hide very different realities.

Some properties are destroyed.

Some are standing but unsafe.

Some have limited-use restrictions.

Some simply could not be accessed yet.

That distinction becomes increasingly important as communities move from evacuation into recovery.

────────────────────────────────────────

LILLOOET — RILEY CREEK AND PEAR LAKE

Here’s what we know:

The Squamish-Lillooet Regional District continues to list active Evacuation Orders and Alerts associated with:

• Riley Creek

• Pear Lake

No authoritative overnight rescindment of those Orders was identified before publication.

Riley Creek remains operationally important around the Texas Creek area.

Pear Lake remains a large, multi-jurisdictional wildfire environment.

The weather changes sharply today.

Lillooet is forecast near 30°C.

Showers become increasingly likely.

A thunderstorm is possible this afternoon.

South winds are expected to increase significantly, with gusts potentially reaching approximately 70 km/h.

Showers with thunderstorms are forecast tonight.

Forecast rainfall is approximately 5 to 10 millimetres in the Lillooet environment.

Sunday becomes much cooler near 21°C.

Here’s what we’re watching:

• Riley Creek fire behaviour during the wind increase

• Pear Lake evacuation boundaries

• Thunderstorm outflow

• Lightning

• Timing of rainfall

• Whether 5 to 10 millimetres reaches the active fire areas

• Overnight humidity recovery

• Holdover fires after lightning

Here’s why it matters:

This is potentially useful suppression weather.

But there may be a transition period where wind becomes the dominant variable before meaningful rain arrives.

Strong wind can increase surface fire spread, spotting and tree hazards even as an overall cooler and wetter weather system approaches.

────────────────────────────────────────

BONANZA CREEK — SOUTH CHILCOTIN AND BRIDGE RIVER

Here’s what we know:

The SLRD continues to list an Evacuation Order and Alert associated with the Bonanza Creek wildfire.

No significant overnight evacuation-boundary change was identified before publication.

The region remains operationally complicated because of:

• Remote properties

• Long evacuation routes

• Ranch operations

• Backcountry recreation

• Limited alternate roads

The same regional weather transition affecting Lillooet will influence portions of this environment.

Here’s what we’re watching:

• Order and Alert changes

• Stronger winds

• Thunderstorm activity

• Lightning

• Actual rainfall

• Road conditions

• Holdover fires after the system passes

Here’s why it matters:

In remote areas, evacuation logistics can become as important as fire behaviour.

Moving livestock, trailers or vulnerable residents takes time.

Residents under Alert should continue maintaining readiness even if rainfall begins.

────────────────────────────────────────

TWIN TWO — ELECTORAL AREA C

Here’s what we know:

Twin Two remains under Evacuation Alert.

Its previous Evacuation Order has already been downgraded.

No new escalation was identified in the latest SLRD reporting.

Here’s what we’re watching:

• Whether the Alert can be lifted

• Local access

• Wind

• Rainfall

• Lightning and holdover fires

Here’s why it matters:

Twin Two remains one of the clearer examples of improving wildfire conditions.

But an Alert remains an active emergency measure until formally rescinded.

────────────────────────────────────────

FRASER CANYON — BOSTON BAR AND HELLS GATE ENVIRONMENT

Here’s what we know:

The Fraser Canyon remains an important wildfire and transportation environment.

Current highway and local access conditions should be verified immediately before travel because closures and restrictions have changed repeatedly through the incident.

The weather transition is particularly significant here.

Boston Bar is forecast around 30°C today.

South winds are expected to increase to approximately 40 km/h with gusts near 70 km/h.

A thunderstorm is possible this afternoon.

Showers and thunderstorms are forecast tonight, with approximately 5 to 10 millimetres of rain possible.

Sunday cools dramatically to approximately 21°C.

Here’s what we’re watching:

• Highway access

• Remaining wildfire activity

• Danger trees

• Rockfall and slope instability

• Wind gusts

• Thunderstorm outflow

• Rainfall totals

• Rail and utility infrastructure

Here’s why it matters:

The Fraser Canyon contains significant post-fire hazards.

Strong wind matters not only because of fire behaviour.

It can also affect burned and weakened trees, unstable slopes, smoke movement and transportation safety.

A cooler Sunday may improve recovery conditions substantially if meaningful rainfall arrives first.

────────────────────────────────────────

SOUTH OKANAGAN WEATHER TRANSITION

Here’s what we know:

The South Okanagan is moving away from the multi-day heat pattern.

Summerland is forecast near 30°C today.

Showers or thunderstorms are possible.

North winds are forecast around 30 km/h with gusts near 50 km/h.

Sunday becomes substantially cooler near 23°C to 24°C with additional shower potential.

This represents a meaningful short-term improvement from the recent sequence of low-to-mid 30°C temperatures.

Here’s what we’re watching:

• Wind arriving before meaningful precipitation

• Rainfall coverage

• Thunderstorm lightning

• Overnight humidity recovery

• Fire response Sunday morning

• Whether dry fuels begin warming again early next week

Here’s why it matters:

The forecast is encouraging.

But wildfire conditions should be assessed from actual rainfall rather than forecast rainfall alone.

A thunderstorm can soak one drainage and leave another almost untouched.

────────────────────────────────────────

SOUTHEAST BRITISH COLUMBIA

Here’s what we know:

The Southeast remains relevant primarily because of active fires, restrictions and lightning potential rather than one dominant community-threatening incident.

Multiple wildfire Area Restrictions remain active.

Recreational off-road vehicle use on Crown land remains prohibited throughout the Southeast Fire Centre.

Campfire and larger open-fire prohibitions remain in effect.

The weather pattern becomes more unsettled today.

Here’s what we’re watching:

• Thunderstorm development

• Lightning outside useful rainfall

• Outflow winds

• New smoke Sunday through Tuesday

• Holdover-fire detections

• Existing fire response to cooler weather

Here’s why it matters:

Lightning is the principal new-start concern.

A storm can provide useful moisture and generate new wildfire ignitions at the same time.

────────────────────────────────────────

ALBERTA

Here’s what we know:

No significant Alberta wildfire escalation was identified during this morning’s provincial scan.

Recent official provincial and forest-area reporting continues to indicate a substantially quieter wildfire environment than southern British Columbia.

Recent rainfall has reduced broad fire-weather pressure in several Alberta forest areas.

The main near-term weather concern remains thunderstorms.

Here’s what we’re watching:

• Lightning-caused starts

• Holdover fires

• Areas receiving lightning without substantial rain

• Municipal wildfires outside the Forest Protection Area

• Any new Wildfire of Note

• Changes to local fire restrictions

Here’s why it matters:

Alberta currently lacks the broad interface emergency conditions seen in southern British Columbia.

That is an important operational distinction.

It does not mean ignition potential is absent.

────────────────────────────────────────

ENVIRONMENTAL INDICATORS

THE WEATHER TRANSITION IS TODAY'S MOST IMPORTANT FIRE-WEATHER SIGNAL

Here’s what we know:

Yesterday was dominated by heat.

Today is dominated by change.

Across much of the southern Interior:

• Temperatures are falling.

• Winds are increasing.

• Showers are developing.

• Thunderstorms are possible.

That combination can produce very different conditions over a relatively short period.

Here’s what we’re watching:

• Timing of stronger wind

• Timing of meaningful rainfall

• Thunderstorm outflow

• Lightning

• Rapid changes in wind direction

• Spotting

• Tree failure

Here’s why it matters:

A cool, rainy forecast can sound immediately favourable.

Operationally, the sequence matters.

If strong winds arrive several hours before substantial rainfall, a fire can experience a short period of increased activity before conditions improve.

────────────────────────────────────────

RAINFALL — POTENTIALLY MEANINGFUL, BUT UNEVEN

Here’s what we know:

Some wildfire-affected areas may finally receive useful rainfall.

Around Lillooet and Boston Bar, approximately 5 to 10 millimetres is forecast tonight.

Summerland also has showers expected tonight and Sunday.

This would be more meaningful than the isolated brief showers seen in several areas earlier in the month.

Here’s what we’re watching:

• Actual measured precipitation

• Geographic coverage

• Duration of rainfall

• Moisture penetration

• Locations that miss the main rain bands

Here’s why it matters:

Five or ten millimetres can meaningfully affect fine fuels if it reaches the fire.

But that does not automatically reset deeper drought.

Large woody fuels, deep organic material and seasonally dry soils respond more slowly.

────────────────────────────────────────

DROUGHT AND FIRE-WEATHER INDICATORS

Here’s what we know:

Longer-term dryness remains part of the wildfire environment across portions of southern British Columbia.

Drought Code, Buildup Index and Fine Fuel Moisture Code vary by weather station and cannot responsibly be represented with one regional number.

The current operational indicators provide a clearer picture:

• Bald Range remains active while re-entry expands.

• Pear Lake, Riley Creek and Bonanza Creek retain active Orders.

• Several days of heat preceded today's weather change.

• Useful rainfall may arrive today and tonight.

• Deeper fuel dryness will respond more slowly than grass and surface fuels.

Here’s what we’re watching:

• Local station Drought Code trends

• Buildup Index

• Fine Fuel Moisture Code

• Rainfall accumulation

• Overnight humidity recovery

• Fire activity Sunday morning

Here’s why it matters:

A fire-weather index is useful when tied to the correct station and location.

One number used across the entire Interior would imply precision that does not exist.

────────────────────────────────────────

LIGHTNING AND HOLDOVER-FIRE POTENTIAL

Here’s what we know:

Lightning becomes a more important watch item today.

Thunderstorms are possible in several southern Interior regions.

Some storms may produce meaningful rainfall.

Others may not.

Here’s what we’re watching:

• Lightning outside rainfall cores

• New smoke Sunday

• New smoke Monday and Tuesday as fuels begin drying again

• Multiple Initial Attack incidents

• Thunderstorm outflow winds

Here’s why it matters:

Lightning-caused fires may not become immediately visible.

Some can smoulder in roots, duff or heavier fuels for one or more days before appearing.

────────────────────────────────────────

GRASS CURING AND HUMAN ACTIVITY

Here’s what we know:

Cured grass and exposed fine fuels remain receptive to ignition before meaningful wetting occurs.

Human-caused starts remain preventable.

Important ignition sources continue to include:

• Trailer chains dragging on pavement

• Hot exhaust systems in dry grass

• Machinery striking rock or metal

• Smoking materials

• Improperly extinguished fires

• Fireworks or exploding targets where prohibited

• Recreational off-road vehicles where prohibited

Here’s what we’re watching:

• Roadside ignitions

• Agricultural and industrial starts

• Equipment use before rainfall

• ORV compliance

• New incidents competing for suppression resources

Here’s why it matters:

Rain later today does not eliminate ignition potential this morning.

Conditions only change when fuels actually receive moisture.

────────────────────────────────────────

RESTRICTIONS AND PROHIBITIONS

Here’s what we know:

KAMLOOPS FIRE CENTRE

• Category 1 campfires remain prohibited.

• Category 2 and Category 3 open fires remain prohibited.

• Recreational off-road vehicle use on Crown land remains prohibited.

CARIBOO FIRE CENTRE

• Category 1 campfires remain prohibited.

• Category 2 and Category 3 open fires remain prohibited.

• Recreational off-road vehicle use remains prohibited within the designated 100 Mile House Forest District area.

SOUTHEAST FIRE CENTRE

• Category 1 campfires remain prohibited.

• Category 2 and Category 3 open fires remain prohibited.

• Recreational off-road vehicle use on Crown land remains prohibited.

• Multiple wildfire Area Restrictions remain active.

PRINCE GEORGE FIRE CENTRE

• The recently introduced Category 2 and Category 3 prohibition within the VanJam Fire Zone remains in effect.

No additional major broad prohibition scheduled to take effect within the next 72 hours was identified during this morning’s forward scan.

Here’s what we’re watching:

• Whether weekend rainfall produces future rescindments

• Any new area restrictions associated with lightning-caused starts

• ORV prohibition changes

• Alberta restriction changes

Here’s why it matters:

Weather does not automatically rescind a restriction.

Only the responsible authority can formally change the prohibition.

────────────────────────────────────────

HOMEOWNER IMPLICATIONS

For residents returning home:

• Confirm the exact property has formally moved from Order to Alert or All Clear.

• Do not rely on neighbourhood rumours or an older map.

• Confirm drinking-water status before normal use.

• Treat damaged electrical systems as energized until confirmed safe.

• Watch for burned roots, ash pits and unstable trees.

• Expect utility crews, firefighters and heavy equipment.

• Keep evacuation supplies available while an Alert remains active.

For residents under Evacuation Alert:

• Keep vehicles fuelled and ready.

• Keep medications, identification and essential documents prepared.

• Maintain arrangements for pets, livestock and anyone requiring assistance.

• Know which roads are actually open.

For residents under Evacuation Order:

• Remain outside the area until the responsible authority formally permits return.

• Do not return to inspect property or activate wildfire-protection equipment.

For residents outside evacuation areas:

• Continue basic wildfire maintenance.

• Follow current fire and ORV restrictions.

• Avoid unnecessary ignition sources before meaningful rainfall arrives.

These actions improve readiness.

They are not predictions and cannot guarantee structure survival.

────────────────────────────────────────

WHAT CHANGED SINCE YESTERDAY

BALD RANGE — RE-ENTRY CONTINUES

• Another RDOS property at 23000 Gallaugher Street was downgraded from Evacuation Order to Evacuation Alert Friday.

• Most affected Summerland and RDOS properties are now under Alert rather than Order.

• Approximately 530 affected Summerland properties remained under Order in the latest regional statistics.

• Approximately 391 affected RDOS properties remained under Order.

BALD RANGE — DAMAGE INFORMATION BECOMES MORE PRECISE

Summerland:

• 799 properties inspected.

• 42 destroyed.

• 7 restricted use.

• 2 unsafe.

• 9 inaccessible.

Electoral Area F:

• 204 properties inspected.

• 105 destroyed.

• 5 restricted use.

• 2 unsafe.

• 4 inaccessible.

This replaces the earlier preliminary “approximately 150 structures” figure with a more detailed assessment picture.

BALD RANGE — RESPONSE TRANSITION

• Wildfire response remains active.

• Incident operations are increasingly shifting away from Summerland toward portions of the fire where active burning continues farther west.

• Re-entry and utility restoration continue in populated areas.

SLRD

• Pear Lake remains under Evacuation Order and Alert.

• Riley Creek remains under Evacuation Order and Alert.

• Bonanza Creek remains under Evacuation Order and Alert.

• Twin Two remains under Evacuation Alert.

ENVIRONMENTAL CHANGE

• The multi-day heat sequence breaks today.

• Summerland falls toward approximately 30°C.

• Lillooet falls toward approximately 30°C.

• Boston Bar falls toward approximately 30°C.

• Stronger winds develop across several active wildfire regions.

• Showers and thunderstorms become increasingly likely.

• Approximately 5 to 10 millimetres of rainfall is forecast tonight around Lillooet and Boston Bar.

────────────────────────────────────────

WHAT WE’RE WATCHING NEXT

• Bald Range re-entry

• Remaining Summerland and RDOS Orders

• Active Bald Range western-flank fire

• Additional damage assessment

• Utility and drinking-water restoration

• Pear Lake Evacuation Order

• Riley Creek and Texas Creek

• Bonanza Creek

• Twin Two Alert status

• Fraser Canyon road access

• Wind gusts this afternoon

• Thunderstorm outflow

• Actual rainfall totals tonight

• Whether wind arrives before widespread wetting

• Fire response Sunday morning

• Lightning-caused new starts

• Holdover-fire detections Sunday through Tuesday

• New restrictions associated with lightning starts

• Alberta wildfire activity

────────────────────────────────────────

STRUCTURE DEFENCE TAKEAWAY — BOTTOM LINE

Here’s what we know:

The broad direction is improving.

More Bald Range residents are returning home.

The evacuation footprint continues shrinking.

Damage assessment is becoming more complete.

Transportation and utility recovery continue.

But several active wildfire emergencies remain.

Pear Lake, Riley Creek and Bonanza Creek still have Evacuation Orders within the SLRD.

And today introduces a different kind of operational challenge.

The heat is breaking.

Strong wind, showers and thunderstorms are arriving.

Here’s what we’re watching:

The most important question today is sequence.

Does meaningful rainfall arrive before stronger winds materially affect active fires?

If it does, this weekend could provide one of the more useful suppression windows we have seen in several weeks.

If strong winds arrive first, there may be a short period of increased fire activity before conditions improve.

We will also be watching lightning closely for new starts that may not become visible immediately.

Here’s why it matters:

Wildfire conditions do not change in one direction all at once.

A community can be returning home while firefighters continue battling active fire kilometres away.

A cooler forecast can be favourable while the wind associated with that change creates a short-term concern.

Rain can improve fine-fuel conditions without immediately changing deeper seasonal drought.

That is why wildfire intelligence has to remain local, current and operationally grounded.

Official emergency instructions always take priority.

Wildfire resilience starts before wildfire arrives.
