OPERATIONAL ASSESSMENT

RILEY CREEK EVACUATION ESCALATION SOUTH OF LILLOOET IS TODAY’S MOST SIGNIFICANT DEVELOPMENT

Here’s what we know:

Evacuation action expanded substantially overnight and early this morning around the Riley Creek wildfire south of Lillooet.

The Squamish-Lillooet Regional District issued an Evacuation Order Friday evening for properties in the Texas Creek and Kennedy Road area. The Order replaced portions of an existing Alert, while the surrounding Alert area was also expanded.

Effective at 8:30 a.m. today, T’it’q’et First Nation issued Evacuation Orders for:

• T’it’q’et Indian Reserve #2 — Towinock

• T’it’q’et Indian Reserve #3 — Kilchult, including 1B

The Riley Creek wildfire remains classified as Out of Control.

Elsewhere:

• The Twin Two Creek Evacuation Order remains active east of Lillooet Lake.

• Multiple Evacuation Orders remain active across the Pear Lake and Big Bar wildfire environment.

• A new Cariboo Regional District Evacuation Order was issued Friday for the Fiftynine Creek–Pear Lake area.

• French Bar remains under Evacuation Order.

• Highway 1 remains closed north of Hells Gate because wildfire continues to burn close to the highway.

• Bowers Lake has improved to All Clear.

• Alberta continues to list no Wildfires of Note.

Here’s what we’re watching:

• Further expansion of the Riley Creek Evacuation Order

• Changes affecting T’it’q’et lands, Texas Creek and properties south of Lillooet

• Access along Texas Creek Road and other rural evacuation routes

• Fire behaviour as showers move through the region

• Continuing evacuation pressure around Pear Lake and Fiftynine Creek

• Highway 1 reopening criteria through the Fraser Canyon

• Wind and lightning associated with the weekend weather transition

Here’s why it matters:

The Riley Creek situation now involves regional district properties and First Nations lands under active Evacuation Order.

This is a meaningful escalation in life-safety and evacuation complexity, particularly in an area with rural roads, agricultural properties, limited accommodation and longer travel distances.

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

TODAY’S CONDITIONS

RILEY CREEK — LILLOOET, TEXAS CREEK AND T’IT’Q’ET FIRST NATION

Here’s what we know:

An Evacuation Order remains in effect for numerous properties along Texas Creek Road, Kennedy Road, McNary Road, Purvis Road and Jorgensen Road.

Residents in the Order area have been directed to evacuate north toward Lillooet using Texas Creek Road.

T’it’q’et First Nation has now placed Towinock IR #2 and Kilchult IR #3, including 1B, under Evacuation Order.

Surrounding properties remain under Evacuation Alert and must be prepared to leave on short notice.

The Riley Creek wildfire remains Out of Control. Public-facing wildfire information has not been updated frequently enough to support reporting a precise current size with confidence. The evacuation decisions provide the more meaningful operational indicator this morning.

Lillooet is expected to reach approximately 26°C today, with morning showers and cooler conditions than Friday. Additional showers are possible Sunday.

Temperatures are then forecast to rise rapidly, reaching approximately 34°C Tuesday and 36°C Wednesday.

Here’s what we’re watching:

• Further Order or Alert expansion

• First Nations evacuation information

• Wind direction and fire movement

• Whether showers produce meaningful rainfall across the fire area

• Road access and visibility

• Structure, agricultural and communications exposure

• The effect of renewed heat beginning Monday

Here’s why it matters:

Cooler temperatures and showers can support suppression, but they do not automatically reduce evacuation risk.

Rainfall may be uneven, and heavier fuels can remain dry beneath briefly wetted surfaces. The return of significant heat early next week may test any progress achieved during the weekend.

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

TWIN TWO CREEK — LILLOOET LAKE AND IN-SHUCK-CH CORRIDOR

Here’s what we know:

The Evacuation Order remains active east of Lillooet Lake for properties and recreation areas including:

• Lillooet Lake Estates

• Heather Jean Properties

• Strawberry Point Recreation Site

• Lillooet Lake Lodge

• Twin One Creek Recreation Site

• Multiple properties along the In-Shuck-Ch Forest Service Road

The Order is associated with the Twin Two Creek wildfire.

Conditions around the Lillooet River area are cooler today, with showers possible through Sunday.

A sharp warming trend is forecast beginning Monday, with temperatures climbing into the mid-30s Tuesday and Wednesday.

Here’s what we’re watching:

• Access along the In-Shuck-Ch Forest Service Road

• Changes to the current Evacuation Order

• Fire response to weekend rainfall

• Wind through valleys and drainage systems

• Recreation-site access during the long weekend

• The return of heat early next week

Here’s why it matters:

Remote properties and recreation sites may require more evacuation time than urban neighbourhoods.

Road access, limited alternate routes and large numbers of long-weekend visitors can complicate an otherwise orderly evacuation.

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

PEAR LAKE, FIFTYNINE CREEK AND THE BIG BAR ENVIRONMENT

Here’s what we know:

The Pear Lake wildfire remains a Wildfire of Note and one of the largest active incidents affecting the southern Interior.

BC Wildfire Service continues to list the incident at approximately 66,900 hectares. That figure was last updated earlier in the week and should be treated as an estimate rather than a precise current perimeter.

Multiple Evacuation Orders and Alerts continue across the Thompson-Nicola, Cariboo and Squamish-Lillooet regional district areas.

The Cariboo Regional District issued a new Evacuation Order Friday for the Fiftynine Creek–Pear Lake Fire Area.

Earlier incident listings for Fiftynine Creek showed that fire as extinguished. Current evacuation notices use the combined Fiftynine Creek–Pear Lake geographic name. This appears to reflect evacuation-area naming and the broader Pear Lake fire environment rather than renewed activity on the previously extinguished Fiftynine Creek incident.

Here’s what we’re watching:

• Expansion or reduction of the new Cariboo Order

• Changes around 70 Mile House, Green Lake, Big Bar and Meadow Lake

• Highway 97 access

• Livestock and agricultural movement

• Rural power and communications

• Clarification of incident mapping and evacuation-area naming

• Fire response during the renewed heat expected next week

Here’s why it matters:

Public evacuation-area names do not always correspond neatly to one active wildfire perimeter.

Residents should follow the current mapped Order or Alert for their exact property rather than relying on an individual fire name or an older fire status.

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

CARIBOO — FRENCH BAR AND BOWERS LAKE

Here’s what we know:

French Bar remains under Evacuation Order, with surrounding areas under Evacuation Alert.

Bowers Lake has improved to All Clear following the lifting of its Evacuation Alert Friday.

This is meaningful progress, but it does not indicate uniform improvement across the wider Cariboo.

Here’s what we’re watching:

• Whether the French Bar Order is downgraded

• Additional changes around Fiftynine Creek–Pear Lake

• Rural-road and forest-service-road access

• Livestock and agricultural impacts

• New lightning or holdover-fire detections

• Private water, power and communications reliability

Here’s why it matters:

An All Clear is a significant improvement for the affected community.

However, multiple neighbouring incidents and evacuation areas remain active, and equipment used during preparation should be restored to a ready condition rather than placed into long-term storage.

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

FRASER CANYON — BOSTON BAR, NORTH BEND AND HELLS GATE

Here’s what we know:

Multiple Evacuation Orders and Alerts remain active through the Fraser Canyon wildfire environment.

Highway 1 remains closed because wildfire continues to burn north of Hells Gate in close proximity to the highway.

DriveBC continues to direct travellers toward Highway 3 or Highway 5 as alternate routes.

Boston Bar is expected to reach approximately 26°C today, with showers possible through Sunday.

Significant heat is forecast to return, reaching approximately 35°C Tuesday and 38°C Wednesday.

Smoke from area fires may continue affecting air quality and visibility.

Here’s what we’re watching:

• Highway 1 reopening criteria

• Evacuation-boundary changes

• Water-system reliability in Boston Bar and North Bend

• Power, rail and communications infrastructure

• Slope stability and falling-tree hazards

• The effectiveness of weekend rainfall

• Fire response during next week’s heat

Here’s why it matters:

The Fraser Canyon remains an access and infrastructure emergency as well as a wildfire event.

Even where rain reduces visible fire activity, highway safety, damaged trees, rockfall, smoke and essential-service concerns may continue delaying reopening.

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

SOUTHEAST BRITISH COLUMBIA

Here’s what we know:

Kimberley is expected to reach approximately 31°C today.

Breezy conditions, low humidity and dry vegetation remain meaningful fire-weather concerns today and Sunday.

The St. Mary Lake area remains part of the active regional wildfire environment associated with the Tower Creek fires.

Category 1, Category 2 and Category 3 fire prohibitions remain in effect throughout the Southeast Fire Centre.

Here’s what we’re watching:

• Wind across existing wildfire perimeters

• Holdover fires from previous lightning

• Changes to the St. Mary Lake evacuation status

• Smoke and reduced visibility

• New starts in dry grass or roadside fuels

• Whether forecast showers provide measurable relief

Here’s why it matters:

Wind and low humidity can offset the benefit of cooler temperatures.

The operational concern is not simply the daily high, but whether dry vegetation and stronger winds support increased spread or spotting.

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

CENTRAL OKANAGAN

Here’s what we know:

No current wildfire-related Evacuation Order or Alert was identified for the Central Okanagan during this morning’s review.

Kelowna is forecast near 30°C today, becoming breezy with possible showers.

Sunday is expected to be cooler before temperatures begin rising again Tuesday and Wednesday.

Smoke from regional wildfires may continue affecting air quality.

Here’s what we’re watching:

• Human-caused ignitions during long-weekend recreation

• Wind before or between showers

• Fine-fuel drying after brief rainfall

• Smoke and reduced visibility

• New wildfire starts during next week’s warming trend

Here’s why it matters:

The absence of an evacuation area is positive.

However, cured grass and exposed fine fuels can remain receptive to ignition even when brief showers occur.

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

ALBERTA

Here’s what we know:

Alberta currently lists no Wildfires of Note.

The latest Rocky Mountain House Forest Area update continues to rate wildfire danger as Very High because of hot and dry conditions.

A Fire Advisory remains active across most of the forest area.

A Fire Restriction remains in effect for portions of the Municipal District of Bighorn and Mountain View County within the Forest Protection Area.

Under the restriction:

• Outdoor wood fires on public land, including random camping areas, are prohibited.

• Fireworks and exploding targets are prohibited.

• Safe campfires remain permitted only in specified permanent facilities and locations.

Rocky Mountain House is forecast to reach approximately 34°C today.

Cooler conditions, rain and increasing wind are expected Sunday.

Here’s what we’re watching:

• New starts during today’s heat

• Wind arriving before meaningful rainfall

• Lightning and holdover-fire potential

• Fire Advisory, Restriction or Ban changes

• Human-caused ignitions during long-weekend travel

• Municipal incidents outside the Forest Protection Area

Here’s why it matters:

Alberta’s lack of a Wildfire of Note does not mean wildfire danger is low.

Hot, dry conditions can support rapid initial growth before crews arrive, particularly where cured grass, wind and human activity align.

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

ENVIRONMENTAL INDICATORS

WEEKEND WEATHER TRANSITION

Here’s what we know:

Southern British Columbia is moving from Friday’s heat into a cooler and more unsettled weekend.

Showers are possible across Lillooet, the Fraser Canyon, the Central Okanagan and portions of the southern Interior.

Wind may increase as the weather system moves through.

Rainfall coverage and duration are expected to vary considerably.

Here’s what we’re watching:

• Whether wind arrives before sustained rainfall

• Rainfall reaching active fire perimeters

• Thunderstorm outflow winds

• Lightning outside the main rainfall area

• Control-line exposure

• Smoke movement and highway visibility

Here’s why it matters:

A cooler forecast does not always produce immediate operational improvement.

Wind can temporarily increase fire activity before rain arrives, while brief showers may wet fine fuels without changing deeper dryness.

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

HEAT AND CONSECUTIVE HOT DAYS

Here’s what we know:

The current heat event is easing across much of British Columbia today.

However, another significant warming period is forecast beginning Monday.

By Wednesday, forecast highs reach approximately:

• Lillooet — 36°C

• Boston Bar — 38°C

• 70 Mile House — 33°C

• Kelowna — 34°C

• Kimberley — 31°C

This creates the potential for several consecutive hot days beginning Tuesday in some active-fire regions.

Here’s what we’re watching:

• Fine-fuel drying after weekend showers

• Overnight humidity recovery

• Fire response Tuesday and Wednesday

• Whether current containment progress holds

• Smoke production during afternoon heating

Here’s why it matters:

Rainfall can temporarily improve surface conditions, but rapid warming can reverse that benefit quickly.

The significance of the weekend rain will depend on amount, coverage and how long fuels remain cool and moist afterward.

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

LIGHTNING AND HOLDOVER-FIRE POTENTIAL

Here’s what we know:

Thunderstorms may accompany portions of the weekend weather transition.

Lightning-caused fires can remain concealed in duff, roots and heavier fuels before appearing during warmer and drier conditions.

The return of heat early next week may expose fires started during the weekend.

Here’s what we’re watching:

• Lightning outside meaningful rainfall

• New smoke Monday through Wednesday

• Clusters of new starts

• Thunderstorm outflow winds

• Ignitions near communities and evacuation routes

• Competition for Initial Attack resources

Here’s why it matters:

A storm can produce helpful rain and new ignitions at the same time.

A lack of visible smoke immediately after lightning does not confirm that no fire has started.

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

GRASS CURING AND HUMAN ACTIVITY

Here’s what we know:

The BC Day long weekend is increasing travel, camping, boating, off-highway vehicle use and outdoor work.

Late-summer grass, roadside vegetation and other fine fuels remain capable of quick ignition and spread.

Common preventable ignition sources include:

• Trailer chains dragging on pavement

• Hot exhaust systems in dry grass

• Machinery striking rock or metal

• Improperly extinguished campfires

• Fireworks and exploding targets

• Smoking materials

• Off-highway vehicles operating in cured vegetation

Here’s what we’re watching:

• Roadside and railway ignitions

• Recreation-related starts

• Equipment use in dry grass

• Visitors entering evacuation or suppression areas

• Compliance with prohibitions and restrictions

Here’s why it matters:

Fine-fuel fires can move quickly toward structures, outbuildings, vehicles and fences.

Preventable new starts also draw crews and aircraft away from existing incidents.

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

RESTRICTIONS AND PROHIBITIONS

Here’s what we know:

Category 1 campfires remain prohibited throughout the:

• Kamloops Fire Centre

• Cariboo Fire Centre

• Southeast Fire Centre

Category 2 and Category 3 open fires also remain prohibited throughout these fire centres.

The Coastal Fire Centre continues to prohibit Category 2 and Category 3 open fires. Category 1 campfire restrictions vary by forest district.

Restrictions have recently been reduced in portions of the Northwest and Prince George Fire Centres. Those changes do not affect the continuing campfire prohibitions in southern British Columbia.

Alberta restrictions continue to vary by forest area, municipality, park and local jurisdiction.

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

Here’s what we’re watching:

• Restrictions associated with next week’s heat

• Local rules that exceed provincial requirements

• Alberta Fire Advisory, Restriction or Ban changes

• Human-caused wildfire activity during the long weekend

Here’s why it matters:

Restrictions are specific to location and activity type.

Anyone planning a campfire, outdoor burn, fireworks or spark-producing activity should verify the rules for the exact destination immediately before proceeding.

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

HOMEOWNER IMPLICATIONS

For residents under Evacuation Order:

• Leave immediately using the route directed by officials.

• Do not delay departure to activate sprinklers, move machinery or complete property work.

• Bring identification, medications, essential documents and communication devices.

• Follow instructions regarding livestock, trailers and restricted roads.

For residents under Evacuation Alert:

• Confirm whether your exact property is within the mapped area.

• Keep vehicles fuelled and positioned for departure.

• Arrange transportation for pets, livestock and anyone requiring assistance.

• Confirm primary and alternate evacuation routes.

• Test pumps, generators and private water systems.

• Move easily transported combustible materials away from structures only where it remains safe.

For residents outside evacuation areas:

• Verify current restrictions before outdoor work or recreation.

• Remove dry debris from decks, gutters and areas immediately beside structures.

• Avoid parking or operating hot equipment in dry grass.

• Check hoses, pumps, generators and rooftop systems before urgent use.

• Continue monitoring after rainfall because conditions may dry quickly next week.

These actions improve readiness. They are not predictions and cannot guarantee structure survival.

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

WHAT CHANGED SINCE YESTERDAY

The most significant escalation:

• An Evacuation Order was issued Friday evening for properties in the Texas Creek and Riley Creek area south of Lillooet.

• T’it’q’et First Nation issued Evacuation Orders effective at 8:30 a.m. today for Towinock IR #2 and Kilchult IR #3, including 1B.

Additional evacuation change:

• The Cariboo Regional District issued a new Evacuation Order Friday for the Fiftynine Creek–Pear Lake Fire Area.

Meaningful improvement:

• The Bowers Lake Evacuation Alert was lifted to All Clear.

Continuing operational concerns:

• The Riley Creek wildfire remains Out of Control.

• The Twin Two Creek Evacuation Order remains active east of Lillooet Lake.

• Multiple Pear Lake and Big Bar Orders and Alerts remain active.

• French Bar remains under Evacuation Order.

• Multiple Fraser Canyon evacuation areas remain active.

• Highway 1 remains closed north of Hells Gate.

• Alberta continues to list no Wildfires of Note.

Environmental change:

• Cooler conditions and showers are moving into several active-fire regions.

• Significant heat is forecast to return beginning Monday and intensify Tuesday and Wednesday.

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

WHAT WE’RE WATCHING NEXT

• Riley Creek evacuation expansion

• T’it’q’et First Nation evacuation information

• Texas Creek Road access

• Twin Two Creek and Lillooet Lake evacuation status

• Pear Lake and Fiftynine Creek–Pear Lake evacuation boundaries

• French Bar Evacuation Order

• Highway 97 access

• Highway 1 reopening through the Fraser Canyon

• Boston Bar and North Bend essential-service reliability

• Weekend wind, rainfall and lightning

• Holdover-fire detections beginning Monday

• Fire response during next week’s renewed heat

• Newly affected communities or First Nations jurisdictions

• Confirmed structure, agricultural, utility, highway, rail or communications impacts

• Alberta wildfire-danger and restriction changes

• Any new prohibition scheduled within the next 72 hours

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

STRUCTURE DEFENCE TAKEAWAY

Here’s what we know:

The Riley Creek escalation south of Lillooet is today’s most important development.

Regional district properties and T’it’q’et First Nation lands are now under Evacuation Order, while surrounding residents remain on Alert.

The Twin Two Creek, Pear Lake, French Bar and Fraser Canyon environments also remain operationally significant.

Bowers Lake has improved to All Clear, and cooler conditions with showers may provide suppression opportunities in several areas this weekend.

Alberta continues to report no Wildfires of Note, although Very High danger and localized restrictions remain in the Rocky Mountain House Forest Area.

Here’s what we’re watching:

The next meaningful changes will involve Riley Creek evacuation boundaries, the effectiveness of weekend rainfall, road access and how active fires respond when significant heat returns early next week.

Here’s why it matters:

Wildfire conditions remain uneven.

An All Clear, a new First Nations Evacuation Order, cooler weather and an approaching heat event can all occur within the same reporting period.

The appropriate response remains calm, location-specific readiness guided by the authority responsible for the exact community or property.

Wildfire resilience starts before wildfire arrives.
