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

This report summarizes current publicly available operational and environmental information. Wildfire conditions, evacuation boundaries and road access can change quickly. Official emergency instructions and transportation notices always take priority.

OPERATIONAL ASSESSMENT

ELEVATED OPERATIONAL ACTIVITY

British Columbia continues to manage several significant interface and rural wildfires, with active evacuation measures affecting the Fraser Canyon, South Cariboo, Bonaparte Plateau and East Kootenay.

The most meaningful new development is in the Kimberley area, where a city-wide Evacuation Alert has been issued due to the Matthew Creek wildfire. A separate Alert remains active for the St. Mary Lake area due to the Tower Creek fires.

Brunswick Creek remains operationally significant because multiple Evacuation Orders continue across the Boston Bar, North Bend, Nahatlatch and Boothroyd corridor.

Alberta continues to list no Wildfires of Note. However, very high wildfire danger and a fire advisory remain in effect in the Calgary Forest Area.

Here’s what we know:

Multiple British Columbia communities, rural properties and First Nations jurisdictions remain under Evacuation Alerts or Orders.

Here’s what we’re watching:

Whether the Kimberley-area fires produce further evacuation changes, whether winds alter fire behaviour around Brunswick Creek, and whether the South Cariboo and Bonaparte Plateau incidents create additional community or access impacts.

Here’s why it matters:

The current operational picture is being shaped by local exposure rather than the provincial wildfire count alone. Fires close to communities, First Nations lands, rural road networks or major transportation corridors require the greatest attention.

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

TODAY’S CONDITIONS

KIMBERLEY AND ST. MARY LAKE — EAST KOOTENAY

Here’s what we know:

The entire City of Kimberley remains under an Evacuation Alert due to the Matthew Creek wildfire.

A separate Evacuation Alert remains active for the St. Mary Lake area due to the Tower Creek and Tower Creek #2 wildfires.

The Kimberley Alert affects all properties within the municipal boundary. The St. Mary Lake Alert affects rural properties along the St. Mary Lake Road corridor.

The current public evacuation information confirms that these incidents remain operationally significant. No city-wide Evacuation Order was listed at the time of this review.

Here’s what we’re watching:

• Any escalation from Alert to Order

• Changes to the Kimberley municipal alert boundary

• Expansion along St. Mary Lake Road

• Fire movement toward homes, utilities or community infrastructure

• Impacts to Highway 95A, local roads or emergency access

• Meaningful suppression progress or status changes

Here’s why it matters:

This is currently one of British Columbia’s most significant community-exposure situations because an entire incorporated city has been placed under Alert.

An Evacuation Alert is not a prediction that an Order will follow. It does mean residents should be prepared to leave on short notice and should follow the City of Kimberley and Regional District of East Kootenay directly.

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

BRUNSWICK CREEK V10742 — FRASER CANYON

Here’s what we know:

Brunswick Creek remains operationally significant because evacuation measures continue across a wide section of the Fraser Canyon.

Active Orders remain listed for areas including:

• Boston Bar

• North Bend and Chaumox Road

• Nahatlatch and North Boothroyd

• Fishblue Lake

• Canyon Alpine

• Boothroyd Indian Band areas

• Boston Bar First Nation reserves

No new evacuation-boundary expansion was identified during this morning’s review.

Here’s what we’re watching:

• Wind shifts that could affect established fire lines

• Changes to Boston Bar or North Bend evacuation areas

• Newly confirmed structure or infrastructure impacts

• Effects on Boothroyd Indian Band, Boston Bar First Nation or other nearby jurisdictions

• Highway 1 access, delays or operational restrictions

• Measurable containment or suppression progress

Here’s why it matters:

This remains a complex interface incident involving steep terrain, homes, First Nations communities and a nationally important transportation corridor.

A lack of a new evacuation notice this morning does not mean the incident is resolved. Residents and travellers should continue checking current local and DriveBC information.

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

FRENCH BAR CREEK K70748 — BONAPARTE PLATEAU

Here’s what we know:

Evacuation measures remain active around French Bar Creek.

The Thompson-Nicola Regional District maintains an Evacuation Order near Lone Cabin Creek and Empire Valley Road, along with a wider Evacuation Alert across portions of Electoral Area E.

A separate Alert remains in effect for the French Bar Fire Area through Stswecem’c Xget’tem First Nation and the Cariboo Regional District.

Here’s what we’re watching:

• Further expansion of the Order or Alert areas

• Effects on Stswecem’c Xget’tem First Nation lands

• Changes along Empire Valley Road and other rural routes

• Structure, ranching or livestock impacts

• Meaningful suppression progress

Here’s why it matters:

This incident affects a dispersed rural landscape with limited access, long travel distances and multiple issuing authorities.

Residents should confirm which authority governs their property and should not rely solely on the broader provincial fire map.

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

PEAR LAKE C40983 — KELLY LAKE AREA

Here’s what we know:

Evacuation Alerts remain active near Kelly Lake and across portions of the Bonaparte Plateau.

The affected area spans both the Squamish-Lillooet and Thompson-Nicola regional districts.

No escalation to an Evacuation Order was identified during this morning’s review.

Here’s what we’re watching:

• Any change from Alert to Order

• Fire growth or a confirmed change in direction

• Impacts to Pear Lake Road or Pavilion-Clinton Road

• Newly affected properties or jurisdictions

• Competition for suppression resources with nearby incidents

Here’s why it matters:

The incident affects a sparsely populated area, but limited road options and dispersed rural properties can increase the importance of early preparation.

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

FIFTYNINE CREEK AND SOUTH CARIBOO

Here’s what we know:

Evacuation measures remain active around Big Bar Lake, Meadow Lake, South Green Lake, Poison Lake Road and the Bowers Lake area.

The current South Cariboo picture involves several separate incidents and evacuation areas rather than one isolated fire.

Here’s what we’re watching:

• Changes around Big Bar Lake and Meadow Lake

• Expansion toward additional rural or recreational properties

• Impacts to Highway 97 or connecting rural roads

• Interaction between nearby incidents

• Meaningful containment or suppression progress

Here’s why it matters:

The affected landscape contains homes, acreages, ranches, cabins, campgrounds and private water systems.

People under an Alert should be ready to leave with limited notice and should make livestock and transportation arrangements early.

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

SIGNAL HILL — PEMBERTON

Here’s what we know:

The community-level evacuation threat has been reduced.

The Village of Pemberton and SLRD Area C Evacuation Alerts are no longer listed as active. The Evacuation Order for One Mile Lake Park remains in place to support wildfire operations.

Here’s what we’re watching:

• Further suppression progress

• Rescission of the remaining park Order

• Any unexpected change in fire status or community exposure

Here’s why it matters:

This represents meaningful suppression and emergency-management progress.

The remaining Order should still be respected, but the immediate exposure to the wider Pemberton community has been substantially reduced.

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

ALBERTA

Here’s what we know:

Alberta currently lists no Wildfires of Note.

The Calgary Forest Area continues to report very high wildfire danger. Warm temperatures, wind and drying vegetation are increasing the potential for new fires to start and spread quickly.

A fire advisory remains in effect in the Calgary Forest Area. Fire permits are being considered individually, while existing permits remain valid unless otherwise directed.

There were no active wildfires reported within the Calgary Forest Area in the latest published area update.

Here’s what we’re watching:

• Any new Alberta Wildfire of Note

• New lightning-caused or wind-driven starts

• Changes to fire advisories, restrictions or bans

• Community, First Nations or infrastructure exposure

• Road or access impacts

• Changes in northern Alberta out-of-control fires

Here’s why it matters:

The absence of a Wildfire of Note means there is no currently designated major community or infrastructure threat. It does not mean the potential for new wildfire starts is low.

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

ENVIRONMENTAL INDICATORS

HEAT AND DRYING

Here’s what we know:

Warm and drying conditions continue across parts of the British Columbia Interior and southern Alberta.

The 100 Mile House forecast calls for temperatures rising from approximately 26°C today to near 29°C Tuesday and 30°C Wednesday.

Several consecutive warm days can progressively dry grass, needles, roadside vegetation and other fine fuels, even where deeper fuels retain moisture.

Here’s what we’re watching:

• Consecutive hot days

• Overnight humidity recovery

• Fine-fuel drying

• Whether localized rainfall produces meaningful wetting

• Increasing afternoon fire behaviour

Here’s why it matters:

Wildfire potential develops cumulatively. The effect of several warm, dry days may be more important than one isolated hot afternoon.

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

LIGHTNING AND HOLDOVER-FIRE POTENTIAL

Here’s what we know:

Recent lightning remains an important factor across British Columbia.

Lightning-caused fires may remain concealed in forest litter, roots or heavier fuels before becoming visible during warmer, drier or windier conditions.

Here’s what we’re watching:

• Additional holdover-fire detections

• New clusters of fire starts

• Thunderstorm outflow winds

• Lightning occurring outside meaningful rainfall

Here’s why it matters:

A fire detected today may have originated during an earlier lightning event. Delayed detection does not necessarily indicate a new storm or a sudden regional change.

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

WIND

Here’s what we know:

Wind remains a key short-term variable around established wildfires.

The Calgary Forest Area continues to identify wind as one of the factors contributing to very high wildfire danger.

Here’s what we’re watching:

• Wind shifts near Brunswick Creek

• Valley winds around Kimberley and the Fraser Canyon

• Gusty thunderstorm outflows

• Effects on ember transport and aircraft operations

• Wind arriving before rainfall

Here’s why it matters:

Wind can alter fire direction, increase spotting and change which homes, roads or infrastructure are exposed before a new public perimeter is available.

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

RAINFALL AND DRY PERIODS

Here’s what we know:

Localized showers may provide temporary surface relief, but rainfall has not produced a uniform change across the wildfire-relevant regions of either province.

Short-duration rain may dampen grass and exposed fuels without substantially changing deeper fuel moisture or established wildfire perimeters.

Here’s what we’re watching:

• Rainfall duration and total accumulation

• Areas repeatedly missed by precipitation

• How quickly fine fuels dry after showers

• Whether rain reaches active fire areas

Here’s why it matters:

Rainfall needs to be evaluated by location and duration. A shower near one community should not be interpreted as a regional reduction in wildfire potential.

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

SMOKE AND VISIBILITY

Here’s what we know:

Air-quality warnings for wildfire smoke have affected the Fraser Canyon, South Thompson, Kootenay Lake, southern East Kootenay, Fort Nelson and the B.C. Peace region.

Smoke may reduce visibility and make it harder to judge the location or distance of a wildfire.

Here’s what we’re watching:

• Changes in visibility along highways

• Smoke settling into valleys overnight

• Health impacts for vulnerable residents

• Whether smoke limits aviation or aerial assessment

Here’s why it matters:

Smoke is evidence of wildfire activity somewhere in the broader region, but it is not a reliable indicator of how close a fire is or which direction it is moving.

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

GRASS AND FINE FUELS

Here’s what we know:

Warm weather, wind and drying vegetation can cause grass and fine fuels to become receptive to ignition quickly.

Common human-caused ignition concerns include:

• Vehicles parked over dry vegetation

• Machinery and hot exhaust systems

• Dragging chains or metal

• Campfires and outdoor burning

• Fireworks

• Smoking materials

Here’s what we’re watching:

• Roadside and field curing

• Wind-exposed slopes

• Vegetation around machinery and vehicles

• Fine fuels immediately beside homes, decks and fences

Here’s why it matters:

Fine fuels can carry fire rapidly toward heavier vegetation or structures, even when larger forest fuels remain less receptive.

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

RESTRICTIONS AND HUMAN ACTIVITY

Fire prohibitions and advisories vary by fire centre, municipality, First Nation, park and land jurisdiction.

Anyone planning outdoor burning, a campfire or work that may produce sparks should verify the rules for the exact location before proceeding.

During a period with multiple significant incidents, preventable human-caused fires place additional demand on crews, aircraft and equipment.

Legally permitted does not always mean operationally appropriate. Activities producing flame, heat or sparks should be reconsidered during hot, dry or windy conditions.

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

HOMEOWNER IMPLICATIONS

For residents under an Evacuation Alert:

• Follow the issuing local authority or First Nation.

• Keep vehicles fuelled and positioned for departure.

• Prepare medications, identification and essential documents.

• Make arrangements for pets, livestock and mobility needs.

• Confirm more than one possible route where geography permits.

• Test pumps, generators, hoses and private water systems.

• Remove easily moved combustible items from beside structures when safe.

For residents near an active fire but outside an evacuation area:

• Monitor official local and provincial sources.

• Review how long it would realistically take to leave.

• Check road conditions before travelling.

• Avoid unnecessary ignition-producing activities.

• Do not rely solely on smoke, unofficial maps or social-media reports.

These steps improve readiness. They do not predict wildfire behaviour or guarantee structure survival.

Do not delay an evacuation to activate sprinklers, move equipment or continue property preparation.

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

WHAT CHANGED SINCE YESTERDAY

The most significant new development is the issuance of a city-wide Evacuation Alert for Kimberley and a separate Alert for the St. Mary Lake area.

These Alerts create substantially greater direct community exposure than was present in the previous morning report.

The Pemberton situation has improved. Community Evacuation Alerts are no longer active, although the One Mile Lake Park Order remains in place.

No new Alberta Wildfire of Note has been designated.

No newly posted evacuation expansion for Brunswick Creek was identified during this morning’s review. Existing Orders remain active and operationally significant.

No fast-changing fire-size figure has been carried forward where it could not be independently reverified through the current public incident record.

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

WHAT WE’RE WATCHING NEXT

• Any Kimberley escalation from Alert to Order

• Changes around St. Mary Lake

• Status and suppression progress on Matthew Creek and the Tower Creek fires

• Brunswick Creek wind effects and Highway 1 access

• Changes to Boston Bar, North Bend or First Nations evacuation areas

• French Bar Creek and Pear Lake evacuation changes

• South Cariboo fire movement and rural access

• Additional holdover-fire detections

• Consecutive hot days in the Interior

• Any new BC or Alberta Wildfire of Note

• Changes to prohibitions, advisories or road access

• Confirmed structure or infrastructure impacts

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

STRUCTURE DEFENCE TAKEAWAY

Here’s what we know:

British Columbia continues to manage several operationally significant wildfires, with the Kimberley area now representing the largest newly affected population centre.

Brunswick Creek, the South Cariboo fires and the Bonaparte Plateau incidents remain active and continue to affect evacuation planning across rural and First Nations jurisdictions.

Alberta has no designated Wildfire of Note, but very high wildfire danger continues in the Calgary Forest Area.

Here’s what we’re watching:

The next meaningful developments are most likely to involve evacuation-boundary changes, wind effects, newly detected holdover fires, transportation access and measurable suppression progress.

Here’s why it matters:

The wildfire picture remains active, but risk is local.

Most people in British Columbia and Alberta are not under immediate threat. Those near active incidents should prepare early, follow their issuing authority and avoid treating broad environmental indicators as predictions for an individual property.

This is a time for calm attention, practical readiness and careful use of official information.
