British Columbia & Alberta

Thursday, July 23, 2026

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, road access and restrictions can change quickly. Official emergency instructions and transportation notices always take priority.

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

OPERATIONAL ASSESSMENT

HIGH OPERATIONAL ACTIVITY IN BRITISH COLUMBIA

The most meaningful overnight and early-morning developments are concentrated across the South Cariboo, Bonaparte Plateau, Fraser Canyon and southern Chilcotin.

New or expanded evacuation actions now affect:

• Big Bar Lake, Meadow Lake and Beaverdam Lake

• Poison Lake Road toward Highway 97

• The Village of Clinton

• The Bourgeois Creek Fire Area

• The Bonanza Creek Fire Area

• The South Chilcotin Mountains

• Areas north of Gold Bridge

• The Texas Creek area

The Fraser Canyon remains one of the province’s most complex incidents. Highway 1 remains closed at Boston Bar because of wildfire, multiple Evacuation Orders remain active, and Boston Bar and North Bend are also dealing with water-system impacts.

Kimberley and the St. Mary Lake area remain under Evacuation Alert. Suppression work continues, but increasing winds associated with an approaching cold front are an important operational variable through Saturday.

Alberta continues to list no Wildfires of Note. The Calgary Forest Area remains under a fire advisory with very high wildfire danger in the latest published area update.

Here’s what we know:

British Columbia’s operational picture expanded again on July 22 and early July 23. The changes are not limited to one fire; several separate incidents are now affecting communities, rural properties, parks and access routes across a broad Interior corridor.

Here’s what we’re watching:

Whether new Alert areas escalate, whether current Orders expand or contract, the effect of increasing winds, Highway 1 access through Boston Bar, and whether suppression progress around Kimberley can be maintained.

Here’s why it matters:

The current concern is the number of communities and jurisdictions affected simultaneously—not simply the number of active fires. Rural evacuations may involve relatively few homes, but limited road options, livestock, long travel distances and private water systems can make preparation more complex.

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

TODAY’S CONDITIONS

SOUTH CARIBOO AND BONAPARTE PLATEAU

Here’s what we know:

The Thompson-Nicola Regional District expanded the Evacuation Order for the Big Bar Lake, Meadow Lake and Beaverdam Lake areas on July 22.

The surrounding Evacuation Alert was also expanded from Poison Lake Road toward Highway 97.

The Village of Clinton is now under Evacuation Alert.

Additional evacuation actions remain active across the broader South Cariboo and Bonaparte Plateau, including:

• Fiftynine Creek

• Bowers Lake

• South Green Lake

• French Bar Creek

• Pear Lake

• Big Bar Lake

• Meadow Lake

• Beaverdam Lake

• Poison Lake Road

Conditions around 100 Mile House remain hot and smoky. The current Environment and Climate Change Canada forecast calls for a high near 31°C, widespread smoke, a chance of late-afternoon showers and northwest winds developing during the afternoon.

Here’s what we’re watching:

• Any expansion toward Highway 97

• Further changes affecting Clinton

• Movement around Big Bar, Meadow and Beaverdam lakes

• Afternoon wind effects

• New smoke columns or holdover-fire detections

• Road access for rural residents, ranches and recreational properties

• Whether localized showers produce meaningful wetting or only brief surface relief

Here’s why it matters:

This is now a wide rural-interface cluster rather than one isolated incident.

The affected landscape includes homes, cabins, ranches, campgrounds, parks and limited-access roads. Residents under Alert should be prepared before livestock, trailers, generators or private water systems become last-minute concerns.

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

SOUTH CHILCOTIN / GOLD BRIDGE / TEXAS CREEK

Here’s what we know:

A new Evacuation Order was issued July 22 for the South Chilcotin Mountains area.

A new Evacuation Alert was issued for the area north of Gold Bridge in Squamish-Lillooet Regional District Electoral Area A.

An additional Evacuation Alert was issued for the Texas Creek area early July 23.

These are separate operational actions and should not be interpreted as one continuous evacuation zone without consulting the official maps.

Here’s what we’re watching:

• Whether the Gold Bridge or Texas Creek Alerts escalate

• Access through remote mountain roads

• Newly affected recreational users, seasonal properties or rural residences

• Any coordination requirements involving nearby First Nations jurisdictions

• Fire behaviour as daytime temperatures rise and winds increase

Here’s why it matters:

The South Chilcotin is geographically remote, with long travel distances and limited road networks.

Even an evacuation involving relatively few structures can become operationally important where residents, visitors or livestock depend on one principal route.

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

BOURGEOIS CREEK AND BONANZA CREEK — CARIBOO

Here’s what we know:

The Cariboo Regional District issued a new Evacuation Order for the Bourgeois Creek Fire Area on July 22.

A separate Evacuation Alert was issued for the Bonanza Creek Fire Area.

Current public notices confirm the life-safety actions but do not provide enough consistently current incident detail to publish precise fire sizes or spread rates in this report.

Here’s what we’re watching:

• Whether the Bonanza Creek Alert escalates

• Additional rural properties becoming affected

• Road-access changes

• Structure, ranching or infrastructure impacts

• Updated incident size and stage-of-control information from BC Wildfire Service

Here’s why it matters:

These actions add two more active evacuation areas to an already busy Cariboo response environment.

The operational significance comes from expanding community exposure and resource demand, not from an unverified hectare figure.

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

FRASER CANYON — BRUNSWICK COMPLEX AND BOSTON BAR

Here’s what we know:

Brunswick Creek remains operationally significant alongside the newer fire activity south of Boston Bar.

Current Evacuation Orders include:

• Boston Bar

• Hells Gate

• Scuzzy Creek Forest Service Road and areas south of Boston Bar

• North Bend and Canyon Alpine

• Nahatlatch and North Boothroyd

• Fishblue Lake

• Relevant Boston Bar First Nation and Boothroyd Indian Band jurisdictions

An Evacuation Alert remains in effect from south of Hells Gate toward Alexandra Bridge.

Spuzzum First Nation reserve lands are also under Evacuation Alert.

Highway 1 remains closed at Boston Bar because of wildfire. DriveBC indicates a detour is in effect, and travellers should confirm the current route immediately before departure.

The Fraser Valley Regional District has also issued an urgent boil-water notice for Boston Bar and North Bend when water service is restored. Stage 4 water-conservation measures remain in effect.

Here’s what we’re watching:

• Highway 1 reopening conditions

• Further movement toward Hells Gate, Alexandra Bridge or Spuzzum

• Changes affecting First Nations jurisdictions

• Water, power, communications or rail impacts

• Fire behaviour during continued heat

• Whether suppression progress resumes after the July 21 wind-driven escalation

Here’s why it matters:

This remains a combined wildfire, evacuation, transportation and infrastructure event.

Residents cannot assume their usual direction of travel is available. Water-system impacts also complicate any eventual return and recovery process.

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

KIMBERLEY AND ST. MARY LAKE — EAST KOOTENAY

Here’s what we know:

The City of Kimberley remains under Evacuation Alert due to Matthew Creek.

The St. Mary Lake Evacuation Alert remains active for 66 properties because of the Tower Creek fires.

The latest verified regional update reported:

• Continued work reopening sections of Mark Creek Forest Service Road

• Structure Protection triage completed for identified priority structures and infrastructure

• Helicopters supporting ground crews and cooling active fire areas

• Sixteen pieces of heavy equipment assigned around Matthew Creek

• No substantial overnight growth on the Tower Creek fires

• Indirect suppression strategies continuing in steep terrain

• Tower Creek #2 estimated at approximately 250 hectares

• Tower Creek estimated at approximately 12 hectares

The planned ignition around Matthew Creek did not proceed on July 22.

Several nearby fires—including Bootleg Mountain, Meachen Creek and Tower Creek #3—were reclassified as Being Held.

Here’s what we’re watching:

• Increasing winds between today and Saturday

• Any change from Alert to Order

• Completion of control lines

• Whether afternoon heating increases fire behaviour

• Structure Protection deployment around St. Mary Lake

• A formal stage-of-control change for Matthew Creek or the two primary Tower Creek fires

Here’s why it matters:

There are encouraging suppression indicators, including fires being reclassified as Being Held and continued progress on access and guard construction.

However, the city-wide and St. Mary Lake Alerts remain active. Increasing wind could test current control opportunities, so the appropriate interpretation is progress—not resolution.

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

PEAR LAKE — KELLY LAKE / PAVILION-CLINTON ROAD

Here’s what we know:

Evacuation Orders remain active for the Pear Lake area in the Squamish-Lillooet Regional District and for Downing Provincial Park in the Thompson-Nicola Regional District.

Nearby properties in the Bonaparte Plateau area remain under Alert.

Access restrictions continue through the Order area, and Pavilion-Clinton Road has been affected by the wildfire response.

Here’s what we’re watching:

• Any Order rescission or expansion

• Road reopening

• Guard construction

• Movement toward remaining Alert properties

• Impacts to park or rural infrastructure

Here’s why it matters:

Pear Lake remains an example of a relatively small fire with significant local consequences because it directly affects homes, parks and a limited rural road corridor.

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

ALBERTA

Here’s what we know:

Alberta continues to report no Wildfires of Note.

Conditions vary considerably by forest area:

• The Calgary Forest Area remains at very high wildfire danger under a fire advisory in its latest published update.

• The Peace River Forest Area reported moderate danger after precipitation and no active wildfires.

• The Rocky Mountain House Forest Area reported moderate danger, with areas south of Highway 11 receiving less rainfall.

• The Slave Lake Forest Area reported low danger following recent precipitation.

The Calgary area is under a heat warning, with daytime temperatures in the low-to-mid 30s expected for several days.

Here’s what we’re watching:

• Any newly designated Alberta Wildfire of Note

• Lightning associated with thunderstorms

• Wind and continued drying in southern Alberta

• Fire-advisory, restriction or ban changes

• Community, First Nations or infrastructure exposure

• New municipal incidents outside Alberta’s Forest Protection Area

Here’s why it matters:

Alberta does not currently have a major designated wildfire incident, and rainfall has improved conditions in parts of the province.

Southern Alberta remains the exception. Several hot days, dry vegetation and wind can increase ignition and spread potential even without an existing Wildfire of Note.

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

ENVIRONMENTAL INDICATORS

HEAT AND CONSECUTIVE HOT DAYS

Here’s what we know:

Heat warnings remain in effect for parts of British Columbia and Alberta.

The Fraser Canyon, South Cariboo, East Kootenay and Calgary region have experienced or are continuing through several consecutive hot days.

Here’s what we’re watching:

• Overnight humidity recovery

• Whether smoke limits daytime heating

• Fine-fuel drying

• Heat stress for residents and crews

• The timing and strength of the approaching cold front

Here’s why it matters:

Several consecutive hot days can progressively dry grass, needles and surface fuels.

Heat is not a prediction of fire growth, but it can shorten suppression windows and make new ignitions more responsive to wind.

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

WIND

Here’s what we know:

Increasing winds are expected in the East Kootenay between today and Saturday as a cold front approaches.

Northwest winds are forecast to develop around 100 Mile House this afternoon.

Strong winds were already responsible for rapid operational change near Boston Bar earlier this week.

Here’s what we’re watching:

• Cold-front timing

• Canyon and valley wind shifts

• Gusty winds before rainfall

• Effects on ember transport

• Aircraft limitations

• Whether established guards are tested

Here’s why it matters:

Wind can change exposure faster than a public fire perimeter can be updated.

Residents near active incidents should rely on evacuation authorities rather than interpreting smoke direction or mapped boundaries on their own.

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

LIGHTNING AND HOLDOVER-FIRE POTENTIAL

Here’s what we know:

Recent lightning remains operationally relevant across Interior British Columbia.

Additional fires may continue to emerge several days after the original storms as hidden ignitions become visible during warmer, drier or windier conditions.

Here’s what we’re watching:

• New smoke reports

• Clusters of delayed detections

• Lightning accompanying showers

• New incidents close to existing evacuation areas

• Whether emerging fires affect already committed suppression resources

Here’s why it matters:

A fire first reported today may not have ignited today.

Holdover fires can appear while crews are already managing established community and rural-interface incidents.

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

RAINFALL AND PROLONGED DRYING

Here’s what we know:

Rainfall remains uneven.

Parts of northern and central Alberta have received enough moisture to lower wildfire danger.

Southern British Columbia and Alberta continue to experience more limited or inconsistent rainfall.

Showers are possible in parts of the South Cariboo, but the probability and duration are not sufficient to assume meaningful fuel recovery.

Here’s what we’re watching:

• Rainfall duration

• Areas missed by showers

• Lightning outside the main rainfall area

• Wind associated with storm cells

• How quickly fine fuels dry afterward

Here’s why it matters:

Brief showers may reduce visible fire behaviour temporarily without materially changing deeper fuel moisture or an established perimeter.

Rainfall must be evaluated locally.

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

DROUGHT AND FIRE-WEATHER INDICATORS

Here’s what we know:

Current local Drought Code values were not consistently available at a sufficiently current and comparable scale for all significant incident areas.

No single Drought Code figure has therefore been used to characterize the current provincial situation.

The strongest operational indicators are:

• Consecutive heat

• Increasing wind

• Fine-fuel drying

• Recent lightning

• Active evacuation expansion

• Current fire-behaviour observations

• New and expanded prohibitions

Here’s what we’re watching:

• Updated BC Wildfire Service weather-station data

• Overnight recovery

• Extended dry periods

• Whether the cold front produces meaningful rainfall

• Changes in regional fire-danger ratings

Here’s why it matters:

Avoiding false precision is more useful than carrying forward an old or geographically distant fire-weather value.

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

GRASS CURING AND HUMAN ACTIVITY

Here’s what we know:

Grass, roadside vegetation and other fine fuels are increasingly responsive to heat and wind.

Common ignition concerns include:

• Vehicles parked over dry grass

• Machinery and hot exhaust systems

• Dragging chains or metal

• Outdoor burning

• Campfires

• Fireworks

• Smoking materials

• Generators or pumps operating in dry vegetation

Here’s what we’re watching:

• Roadside and pasture curing

• Fine fuels along evacuation corridors

• Equipment use during afternoon heat and wind

• Human-caused starts near communities

• Public compliance with new prohibitions

Here’s why it matters:

Fine fuels can carry fire rapidly toward heavier vegetation or structures.

During a period of simultaneous lightning and interface incidents, preventable fires compete for the same crews, aircraft and equipment.

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

RESTRICTIONS AND PROHIBITIONS

Here’s what we know:

A Category 1 campfire prohibition takes effect throughout the Southeast Fire Centre at 12:00 noon Pacific Time today.

Anyone with a campfire in the affected area must have it fully extinguished by the noon deadline.

Category 2 and Category 3 open fires are already prohibited throughout the Southeast Fire Centre.

Category 1 campfires are also prohibited throughout the Cariboo and Kamloops fire centres.

Restrictions elsewhere in British Columbia vary by fire centre, district, municipality, park and First Nations jurisdiction.

The Calgary Forest Area remains under a fire advisory.

Here’s what we’re watching:

• Additional provincial prohibition changes

• Municipal or First Nations rules that are more restrictive

• Fireworks, burn-barrel or equipment-related ignitions

• Compliance during the current heat

• Restrictions connected to the approaching cold front and wind

Here’s why it matters:

The Southeast campfire prohibition begins today, not tomorrow.

Rules should be checked for the exact location immediately before any burning or spark-producing activity.

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

HOMEOWNER IMPLICATIONS

For residents under an Evacuation Alert:

• Follow the local government or First Nation that issued the Alert.

• Keep vehicles fuelled and positioned for departure.

• Prepare identification, medications and essential documents.

• Make early arrangements for pets, livestock and mobility needs.

• Confirm current road access and an alternate route where possible.

• Test pumps, generators and private water systems.

• Move easily transported combustible items away from structures when safe.

For residents under an Evacuation Order:

• Leave immediately using the route directed by the issuing authority.

• Do not assume the usual road remains open.

• Do not delay evacuation to activate sprinklers, move equipment or continue property work.

• Do not enter closed or restricted roads.

For residents near—but outside—an evacuation area:

• Monitor official local sources.

• Review how long departure would realistically take.

• Avoid unnecessary ignition-producing work during heat and wind.

• Check transportation conditions before travelling.

• Do not treat smoke direction or unofficial maps as evacuation guidance.

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

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

WHAT CHANGED SINCE YESTERDAY

The most meaningful developments are:

• The Big Bar Lake, Meadow Lake and Beaverdam Lake Evacuation Order was expanded.

• The surrounding Poison Lake Road-to-Highway 97 Alert was expanded.

• The Village of Clinton was placed under Evacuation Alert.

• A new Evacuation Order was issued for the Bourgeois Creek Fire Area.

• A new Evacuation Alert was issued for the Bonanza Creek Fire Area.

• A new Evacuation Order was issued in the South Chilcotin Mountains.

• New Alerts were issued north of Gold Bridge and in the Texas Creek area.

• Highway 1 remains closed at Boston Bar.

• Boston Bar and North Bend are now also managing boil-water and Stage 4 conservation measures.

• Several smaller East Kootenay fires were reclassified as Being Held, representing meaningful suppression progress.

• The Southeast Fire Centre Category 1 campfire prohibition begins at noon today.

No new Alberta Wildfire of Note was identified.

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

WHAT WE’RE WATCHING NEXT

• Any escalation around Clinton

• Big Bar Lake, Meadow Lake and Beaverdam Lake evacuation changes

• Gold Bridge, Texas Creek and South Chilcotin access

• Bourgeois Creek and Bonanza Creek growth

• Highway 1 reopening through Boston Bar

• Water, power, rail or communications impacts in the Fraser Canyon

• Increasing wind around Kimberley and St. Mary Lake

• Whether Matthew Creek suppression gains are maintained

• Additional holdover-fire detections

• Cold-front wind and rainfall timing

• Further restriction or prohibition changes

• Any new BC or Alberta Wildfire of Note

• Confirmed structure or infrastructure impacts

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

STRUCTURE DEFENCE TAKEAWAY

Here’s what we know:

British Columbia’s wildfire situation expanded again across several rural and community-interface areas.

The South Cariboo and Bonaparte Plateau now involve broader evacuation exposure, Clinton is under Alert, and new evacuation actions have been issued in the South Chilcotin and Cariboo.

The Fraser Canyon remains a combined wildfire, transportation and infrastructure emergency.

Kimberley and St. Mary Lake remain under Alert, although some nearby fires have shown meaningful suppression progress.

Alberta currently has no Wildfire of Note, but southern Alberta remains hot and dry.

Here’s what we’re watching:

The next important changes will likely involve evacuation boundaries, Highway 1 access, increasing wind, newly detected holdover fires and whether current suppression gains can be maintained.

Here’s why it matters:

The provincial picture is active, but individual risk remains local.

Residents should base decisions on the current evacuation authority, available road access and the incident affecting their specific area—not on broad provincial numbers or assumptions from smoke.

This is a time for calm attention, early preparation and strict reliance on authoritative information.
