British Columbia & Alberta

Saturday, September 5, 2026

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

Wildfire conditions, evacuation boundaries, road access, restrictions and recovery hazards can change quickly.

Official 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 broad wildfire picture continues to improve across British Columbia and Alberta.

No major new rapidly expanding community-threatening wildfire, large evacuation expansion, new critical-infrastructure threat or significant Alberta escalation was identified during this morning’s authoritative-source scan.

The most important change since yesterday is at Bald Range.

BC Wildfire Service rescinded the Bald Range Area Restriction at noon Friday, September 4, because fire behaviour and activity had decreased enough that firefighters no longer required the access restriction to operate safely and efficiently.

That is a meaningful suppression milestone.

It does not mean the Bald Range wildfire is extinguished.

BC Wildfire Service specifically cautions that the wildfire remains an active worksite and that hazards may include unstable fire-damaged trees, ash pits and residual smoke.

RDOS community-recovery controls remain separate from the BC Wildfire Service Area Restriction.

Specified properties in Faulder, South Meadow Valley and Callan Road remain subject to the RDOS Prohibit Entry Order.

Princeton-Summerland Road remains closed to through traffic except for residents, permit holders and authorized recovery crews.

Pear Lake remains the principal wildfire evacuation environment within the SLRD, but it is now Alert-only.

There are no active wildfire Evacuation Orders in the SLRD.

The Cariboo Regional District has also moved the remaining French Bar wildfire evacuation area to All Clear.

Spuzzum First Nation remains under Evacuation Alert following the earlier downgrade from Order.

EmergencyInfoBC continues to list several additional First Nations wildfire emergencies, including Okanagan Indian Band, Stswecem’c Xget’tem First Nation, Lytton First Nation, Coldwater Indian Band and Llenllenéy’ten.

The freshness of those individual jurisdictional updates varies. Older property or reserve boundaries are therefore not being repeated as though they were freshly verified this morning.

In the Revelstoke backcountry, the Johnson Creek wildfire near Beaton remains associated with an Evacuation Alert in the latest published emergency information.

The Lew Creek Evacuation Order near Trout Lake has been rescinded.

In Alberta, conditions have improved significantly around Grande Prairie.

The Grande Prairie Forest Area is now at Low wildfire danger.

Wildfire GWF058 near the B.C. border is Under Control at approximately 25 hectares.

No Alberta Emergency Alert is active.

Here’s what we’re watching:

The short-term environmental picture remains favourable.

Southern Interior temperatures are generally cool to moderate today.

Summerland reaches approximately 22°C.

Clinton reaches approximately 16°C.

Cranbrook reaches approximately 18°C.

Grande Prairie reaches approximately 17°C.

The more important weather factor today is localized thunderstorm potential.

Summerland and Clinton both carry afternoon thunderstorm risk.

Cranbrook has a 60% chance of showers, with showers continuing tonight and Sunday.

Rain and several cool nights have improved surface-fuel conditions substantially.

However, BC Wildfire Service continues to caution that forest fuels remain dry in many parts of the province despite recent precipitation.

Here’s why it matters:

The emergency footprint is shrinking faster than the seasonal fuel problem.

Those are different things.

Evacuations can end.

Area Restrictions can be rescinded.

Campfires can become legal.

At the same time, deep organic fuels, large woody material and areas that missed meaningful rainfall can remain dry.

The practical interpretation is encouraging conditions with continued late-season awareness.

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

TODAY'S CONDITIONS

BALD RANGE — SUMMERLAND / FAULDER

Here’s what we know:

The Bald Range incident reached another significant recovery milestone Friday.

BC Wildfire Service rescinded its Area Restriction at noon September 4.

The reason was straightforward:

Fire behaviour and activity have decreased enough that suppression crews no longer need to restrict public access in order to work safely and effectively.

The fire nevertheless remains an active wildfire worksite.

BC Wildfire Service warns of potential hazards including:

• Fire-damaged and unstable trees

• Hot or difficult-to-detect ash pits

• Residual smoke

• Active wildfire personnel and equipment

The RDOS recovery access system remains in effect independently of the BC Wildfire Service decision.

The RDOS continues to maintain a Prohibit Entry Order for designated properties in:

• Faulder

• South Meadow Valley

• Callan Road

Authorized residents and approved individuals may enter using valid access permits.

Princeton-Summerland Road remains closed to through traffic except for residents, permit holders and authorized recovery crews.

The RDOS continues emphasizing:

• Faulder Water System protection

• Meadow Valley aquifer protection

• Debris removal

• Property assessment

• Utility restoration

• Insurance and rebuilding activity

• Hazard-tree awareness

Summerland conditions at 8:00 a.m.:

• Temperature approximately 13°C

• Relative humidity approximately 84%

• Very light wind

Forecast:

• High approximately 22°C

• 40% chance of showers

• Risk of an afternoon thunderstorm

• North wind developing around 20 km/h

Sunday reaches approximately 23°C.

Here’s what we’re watching:

• RDOS Prohibit Entry Order

• Princeton-Summerland Road reopening

• Water and aquifer protection

• Deep hotspots

• Smoke from within the fire perimeter

• Hazard trees

• Afternoon thunderstorms

• Fine-fuel drying beginning early next week

Here’s why it matters:

The difference between the two access systems is important.

BC Wildfire Service no longer needs a broad Area Restriction for suppression.

The RDOS still has community-level access controls because recovery hazards remain.

Fire control and safe community recovery do not necessarily happen on the same timeline.

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

PEAR LAKE — SOUTH CARIBOO / SLRD AREA B

Here’s what we know:

Pear Lake remains under Evacuation Alert.

The final SLRD Evacuation Order was downgraded Thursday evening.

As of the SLRD’s September 4 update, Pear Lake is the only wildfire currently affecting communities in the SLRD and the only wildfire evacuation measure listed is:

• Evacuation Alert — Pear Lake, Electoral Area B

There are no active wildfire Orders in Electoral Areas A, B, C or D.

The broader Cariboo emergency picture has also improved.

The Cariboo Regional District lifted its final French Bar Fire Area Alert to All Clear on September 3.

Clinton conditions this morning are cool and moist:

• Approximately 7°C

• 100% relative humidity

• Light southeast wind

Forecast:

• High approximately 16°C

• 30% chance of late-afternoon showers

• Risk of a thunderstorm

• Overnight low approximately 4°C

Sunday becomes mainly sunny around 19°C.

Here’s what we’re watching:

• Pear Lake Alert rescindment

• Deep fire activity

• Saturday thunderstorm potential

• Rural road conditions

• Ranch and livestock recovery

• Fine-fuel response during Sunday and early-week drying

Here’s why it matters:

The evacuation picture has improved dramatically.

But Alert status still means residents should remain capable of leaving again if conditions change.

Cool temperatures and high humidity support suppression, while an afternoon thunderstorm can still produce lightning or localized outflow wind.

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

FRASER CANYON — AINSLIE CREEK / SPUZZUM

Here’s what we know:

The Fraser Canyon remains an active wildfire-recovery environment.

Spuzzum First Nation remains under Evacuation Alert following the earlier downgrade from Order.

The Fraser Valley Regional District has rescinded its wildfire evacuation measures.

Ainslie Creek remains subject to a BC Wildfire Service Area Restriction scheduled through September 15 unless rescinded earlier.

Highway 1 remains open through the wildfire-affected corridor.

Travellers should continue checking DriveBC before departure because wildfire recovery may still involve:

• Traffic control

• Utility restoration

• Danger-tree operations

• Slope work

• Rockfall

• Temporary delays

Here’s what we’re watching:

• Spuzzum Alert

• Ainslie Creek suppression progress

• Highway 1 operations

• Hazard trees

• Rockfall and slope stability

• Utility restoration

• Any Area Restriction change

Here’s why it matters:

This corridor demonstrates how wildfire impacts outlast the evacuation phase.

The remaining operational hazards are increasingly related to damaged terrain and infrastructure rather than a rapidly advancing fire front.

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

REVELSTOKE BACKCOUNTRY — JOHNSON CREEK / BEATON

Here’s what we know:

The latest published Revelstoke Area Emergency Management information continues to show:

• Johnson Creek wildfire near Beaton — Evacuation Alert

• Lew Creek wildfire near Trout Lake — Evacuation Order rescinded

The Johnson Creek Alert applies to the Fish River Road / Incomappleux River Forest Service Road environment.

Officials continue warning that wildfire and post-fire hazards may remain even after the downgrade from Order.

A scheduled September 4 update was not visible in the authoritative public page before publication this morning.

The August 31 Alert is therefore treated as the latest verifiable published status rather than assumed to have changed.

Here’s what we’re watching:

• Fresh Johnson Creek update

• Alert rescindment

• Incomappleux road access

• Remote-property access

• Residual fire activity

Here’s why it matters:

Remote wildfire incidents can remain operationally complex even when only a small number of properties are involved.

Road access and distance from emergency services matter.

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

FIRST NATIONS WILDFIRE MEASURES

Here’s what we know:

EmergencyInfoBC continues to list several active wildfire emergencies involving First Nations jurisdictions.

The most recently updated include:

• Okanagan Indian Band — updated September 4

• Spuzzum First Nation — updated September 2

• Stswecem’c Xget’tem First Nation — updated August 31

• Lytton First Nation — updated August 31

• Coldwater Indian Band — updated August 29

• Llenllenéy’ten / High Bar First Nation — updated August 28

Okanagan Indian Band continues to have wildfire evacuation measures in place according to the September 4 EmergencyInfoBC update.

Because the precise property-level boundaries are maintained by the issuing First Nation, residents should use the current Band emergency information rather than relying on older regional summaries.

Here’s what we’re watching:

• Fresh rescindments

• Order-to-Alert downgrades

• Road access

• Utility restoration

• Community re-entry

Here’s why it matters:

A shrinking provincial evacuation footprint should not obscure emergency measures within First Nations jurisdictions.

Those measures carry the same operational importance for the affected residents.

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

SOUTHEAST BRITISH COLUMBIA

Here’s what we know:

The Southeast remains in a cool and unsettled weather pattern.

Cranbrook at 9:00 a.m. MDT:

• Approximately 10°C

• Relative humidity approximately 79%

• Light west-northwest wind

Forecast:

• High approximately 18°C

• 60% chance of showers

• Showers tonight

• Showers Sunday with a high around 17°C

Recent suppression progress also continues to reduce public-access restrictions.

The Poplar Creek Area Restriction was rescinded Friday at noon.

Poplar Creek remains an active wildfire worksite and is estimated at approximately 664 hectares in the latest BC Wildfire Service bulletin.

BC Wildfire Service similarly rescinded the Hope Creek Area Restriction today.

Here’s what we’re watching:

• Multi-day showers

• Poplar Creek and other remaining active fires

• Holdover lightning

• New smoke as conditions dry later

• Public access around active worksites

Here’s why it matters:

The Southeast fire-weather environment is currently favourable.

But Area Restriction rescindment means access is returning faster than all fire activity disappears.

Fire-damaged trees, ash pits and crews working inside the perimeter can remain hazards.

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

ALBERTA — GRANDE PRAIRIE

Here’s what we know:

Conditions have improved substantially.

The latest Alberta Wildfire update, issued September 4, classifies wildfire danger in the Grande Prairie Forest Area as:

LOW

Alberta Wildfire attributes this to:

• Recent rainfall

• Cooler temperatures

Wildfire GWF058 is now:

• Under Control

• Approximately 25 hectares

• Located near the B.C. border south of Township Road 700 at the end of Range Road 133

Firefighters continue monitoring the wildfire.

There is no active Alberta Emergency Alert.

Grande Prairie weather today is cool.

At 9:00 a.m. MDT:

• Approximately 4°C

• 100% relative humidity

• Fog

• Very light north wind

Forecast:

• High approximately 17°C

• Mainly sunny after morning fog

• Overnight low approximately 3°C with risk of frost

Sunday warms to approximately 21°C.

Monday reaches approximately 22°C.

Tuesday and Wednesday may reach around 24°C.

Here’s what we’re watching:

• GWF058 monitoring

• New human-caused starts

• Fine-fuel drying Sunday through Wednesday

• Harvest and industrial ignition sources

• Any change in Alberta Emergency Alerts

Here’s why it matters:

The immediate Alberta wildfire signal is favourable.

But several dry, sunny days follow the recent rain.

Fine fuels will gradually begin drying again, particularly in exposed grass and harvested agricultural areas.

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

ENVIRONMENTAL INDICATORS

HEAT AND CONSECUTIVE HOT DAYS

Here’s what we know:

There is no significant heat event in the priority regions today.

Representative highs:

• Summerland — approximately 22°C

• Clinton — approximately 16°C

• Cranbrook — approximately 18°C

• Grande Prairie — approximately 17°C

No monitored priority region is entering a sequence of consecutive 30°C-plus days.

A moderate warming trend develops next week.

Summerland may reach approximately 26°C Tuesday and Wednesday.

Clinton reaches approximately 22°C Tuesday and 24°C Wednesday.

Grande Prairie may reach approximately 24°C Tuesday and Wednesday.

Here’s what we’re watching:

• Fine-fuel drying after the wet period

• South-facing slopes

• Grass

• Overnight humidity recovery

Here’s why it matters:

This is not a renewed heat wave.

But several sunny, moderately warm days can still restore fine-fuel receptiveness after rainfall.

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

RAINFALL AND PROLONGED DRYNESS

Here’s what we know:

The recent wet period produced meaningful short-term improvement.

Today is transitioning toward lighter, more localized precipitation.

Summerland:

• 40% chance of showers

Clinton:

• 30% chance of late-afternoon showers

Cranbrook:

• 60% chance of showers

• Further showers tonight and Sunday

Grande Prairie:

• Recent heavy rainfall has ended

The BC Wildfire Service provincial dashboard continues to caution that despite recent precipitation, forest fuel conditions remain dry in many areas of British Columbia.

Here’s what we’re watching:

• Which locations continue receiving showers

• Fine-fuel drying Sunday through Wednesday

• Moisture retention in shaded versus exposed sites

• Deep-fuel and duff response

Here’s why it matters:

Recent rain has unquestionably improved short-term conditions.

But rainfall has not erased the seasonal fuel deficit everywhere.

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

DROUGHT CODE AND FIRE-WEATHER INDICATORS

Here’s what we know:

Recent rainfall, cool temperatures and strong overnight humidity recovery have improved short-duration fire-weather indicators across many stations.

The operational evidence includes:

• Lower wildfire danger in several regions

• Evacuation rescindments

• Area Restriction rescindments

• Campfire prohibition rescindments

• Improved suppression status on existing fires

Fine Fuel Moisture Code reacts relatively quickly to rain and humidity.

Buildup Index and Drought Code recover more slowly.

No single current Drought Code or Buildup Index responsibly represents all of the Okanagan, South Cariboo, Fraser Canyon and Southeast.

For that reason, no broad regional Drought Code number is being published.

Here’s what we’re watching:

• Station-level Drought Code

• Buildup Index

• Fine Fuel Moisture Code

• Drying through next week

• Deep-hotspot response

Here’s why it matters:

Surface recovery and deep seasonal drought occur on different timelines.

Both can be true at the same time.

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

WIND

Here’s what we know:

There is no widespread strong-wind event affecting the priority wildfire regions today.

Summerland may see north wind around 20 km/h this afternoon.

Other areas remain generally light.

The main localized wind concern is thunderstorm outflow.

Here’s what we’re watching:

• Thunderstorm gusts

• Hazard-tree failure

• Smoke movement

• Localized fire response

Here’s why it matters:

Broad wind conditions are favourable.

Short-lived thunderstorm outflow can still produce a localized operational change.

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

LIGHTNING AND HOLDOVER-FIRE POTENTIAL

Here’s what we know:

Thunderstorm risk exists today in parts of the Interior.

Summerland:

• Afternoon thunderstorm risk

Clinton:

• Late-afternoon thunderstorm risk

Cranbrook:

• Showery and unsettled conditions

Here’s what we’re watching:

• Lightning outside meaningful rainfall

• New Initial Attack incidents

• New smoke over the next two to three days

• Holdover fires as skies clear and temperatures rise

Here’s why it matters:

Cool and wet conditions can delay the appearance of lightning fires.

A concealed ignition may become visible only after surrounding fuels begin drying again.

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

GRASS CURING AND HUMAN ACTIVITY

Here’s what we know:

Cured grass remains widespread across Interior B.C. and portions of Alberta.

Recent rain has reduced immediate ignition receptiveness.

The fuel itself remains.

Category 1 campfires are now permitted across the Kamloops, Cariboo, Southeast and Coastal Fire Centres.

As broad restrictions ease, more ignition prevention responsibility returns to individual users.

Common ignition sources remain:

• Campfires not completely extinguished

• Hot exhaust systems over cured grass

• Trailer chains dragging on pavement

• Agricultural and harvesting equipment

• Industrial machinery

• Smoking materials

Here’s what we’re watching:

• Weekend recreation

• Campfire-related starts

• Roadside ignitions

• Agricultural and harvesting starts

• New human-caused fires competing for suppression resources

Here’s why it matters:

Late-season improvement can create a false sense that ignition no longer matters.

Preventing new starts remains one of the easiest ways to reduce pressure on wildfire resources.

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

RESTRICTIONS AND PROHIBITIONS

Here’s what we know:

KAMLOOPS FIRE CENTRE

• Category 1 campfires are permitted.

• Category 2 and Category 3 open-fire restrictions remain subject to current BC Wildfire Service orders.

CARIBOO FIRE CENTRE

• Category 1 campfires are permitted.

• Category 2 and Category 3 open fires remain prohibited.

SOUTHEAST FIRE CENTRE

• Category 1 campfires are permitted.

• Category 2 and Category 3 open fires remain prohibited.

COASTAL FIRE CENTRE

• Category 1 campfires are permitted.

• Larger open-fire restrictions remain location-specific.

BALD RANGE

• BC Wildfire Service Area Restriction was rescinded September 4 at noon.

• RDOS Prohibit Entry Orders remain separate and continue for designated recovery properties.

AINSLIE CREEK

• Area Restriction remains scheduled through September 15 unless rescinded earlier.

SOUTHEAST

• Poplar Creek Area Restriction was rescinded September 4.

• Hope Creek Area Restriction has also been rescinded.

72-HOUR FORWARD SCAN

No new broad wildfire prohibition scheduled to begin during the next 72 hours was identified in the main B.C. or Alberta wildfire regions during this morning’s scan.

Here’s why it matters:

The policy direction remains toward selective easing.

But a restriction being removed does not mean the underlying wildfire or recovery hazard has disappeared.

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

HOMEOWNER IMPLICATIONS

For residents returning after wildfire:

• Verify whether local access is unrestricted or still controlled by a local Prohibit Entry Order.

• Check water and utility advisories.

• Treat damaged electrical infrastructure as energized until confirmed safe.

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

• Be cautious around fire-damaged slopes and drainage channels.

• Expect wildfire, utility and recovery crews.

For residents under Evacuation Alert:

• Maintain a practical ability to leave.

• Keep medications, identification and important documents accessible.

• Maintain transportation plans for pets, livestock and anyone requiring additional time.

For homeowners outside current emergency areas:

The present moderate weather is useful for property work.

Consider:

• Clearing roofs and gutters.

• Removing combustible debris immediately adjacent to structures.

• Keeping grass short.

• Checking hoses, pumps and fittings.

• Replenishing evacuation supplies.

• Confirming current restrictions before burning.

These actions improve readiness.

They are not predictions and cannot guarantee structure survival.

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

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

STRUCTURE DEFENCE TAKEAWAY — BOTTOM LINE

Here’s what we know:

The wildfire environment continues moving in a favourable direction.

Bald Range no longer requires a BC Wildfire Service Area Restriction.

Pear Lake is Alert-only.

The Cariboo’s remaining French Bar evacuation measure has moved to All Clear.

Grande Prairie wildfire danger is Low.

GWF058 is Under Control.

Cool temperatures and recent rainfall have substantially reduced short-term fire-weather pressure.

Those are meaningful operational improvements.

Here’s what we’re watching:

The next phase is drying.

Showers and thunderstorms remain possible today.

Beginning Sunday and becoming more noticeable Tuesday and Wednesday, several regions move back toward sunnier and moderately warmer conditions.

That is not a heat event.

But grass, needles and other fine fuels can respond quickly.

We will also continue watching for lightning holdovers that may become visible as the landscape dries.

Here’s why it matters:

Late-season wildfire conditions often improve unevenly.

Emergency measures may disappear before deep fuels recover.

Roads and water systems may remain damaged after fire activity subsides.

An Area Restriction can be rescinded while individual properties remain under local access controls.

And a legal campfire can still start a wildfire.

The current trend is encouraging.

The useful response is to use the quieter period well.

For firefighters, that means continuing mop-up and patrol.

For affected communities, it means restoring infrastructure and safe access.

For homeowners, it means completing practical wildfire-resilience work while conditions are favourable.

Indicators describe conditions.

They do not predict what an individual wildfire will do next.

Official emergency instructions always take priority.

Wildfire resilience starts before wildfire arrives.
