Tuesday, July 21, 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

ELEVATED OPERATIONAL ACTIVITY

British Columbia continues to manage several operationally significant wildfires affecting communities, rural properties, First Nations jurisdictions, provincial parks and limited-access road networks.

The most important current developments are:

• A city-wide Evacuation Alert remains in effect for Kimberley due to the Matthew Creek wildfire.

• An Evacuation Alert remains in effect for 66 properties near St. Mary Lake due to the Tower Creek fires.

• Pear Lake has escalated from evacuation preparedness to active Evacuation Orders affecting properties, park land and Pavilion-Clinton Road access.

• Brunswick Creek remains operationally significant across the Fraser Canyon, although recent suppression work has produced some measurable progress.

• Multiple South Cariboo and Bonaparte Plateau incidents continue to affect rural evacuation planning.

• Alberta continues to list no Wildfires of Note.

Here’s what we know:

The current operational picture is being driven less by the total number of fires and more by where active incidents intersect with communities, evacuation routes and infrastructure.

Here’s what we’re watching:

Heat, wind, afternoon fire behaviour, newly detected holdover fires, changes to evacuation boundaries and whether current suppression gains can be maintained.

Here’s why it matters:

A fire does not need to be exceptionally large to become operationally important. Community proximity, terrain, road access and the number of available evacuation routes can matter more than size alone.

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

TODAY’S CONDITIONS

KIMBERLEY AND ST. MARY LAKE — EAST KOOTENAY

Here’s what we know:

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

The latest verified regional update estimates Matthew Creek at approximately 567 hectares. The fire is burning in steep, mountainous terrain that is unsafe for direct perimeter attack in some areas.

The latest operational information reported:

• No significant overnight growth on the north or west sides

• A cutblock limiting growth to the south

• Approximately 10 hectares of growth to the east

• Primarily Rank 1–2 fire behaviour during the morning update

• Heavy equipment continuing to reopen a deactivated forest service road to support guard construction

A separate Evacuation Alert remains in effect for 66 properties along the St. Mary Lake Road corridor due to the Tower Creek wildfires.

The combined Tower Creek fire estimate in the latest regional update was approximately 250 hectares. Crews are using indirect strategies because of steep, inaccessible terrain.

Here’s what we’re watching:

• Any change from Alert to Order

• Whether afternoon heating increases fire behaviour

• Progress reopening access for heavy equipment

• Machine-guard construction

• Fire movement toward homes, utilities or local infrastructure

• Any effect on Highway 95A or local evacuation routes

Here’s why it matters:

The reduced morning fire behaviour and improved equipment access are positive operational developments.

However, those gains occurred while smoke and light winds were moderating conditions. They do not yet establish that the fires are contained or that the evacuation alerts can be rescinded.

Kimberley is expected to experience several consecutive hot days, with temperatures forecast to rise above 30°C. Continued heat may progressively dry fine fuels and reduce the durability of short-term suppression advantages.

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

PEAR LAKE C40983 — KELLY LAKE / PAVILION-CLINTON ROAD

Here’s what we know:

Pear Lake remains an active life-safety and access event.

The Squamish-Lillooet Regional District has issued an Evacuation Order for properties in Electoral Area B around Pear Lake Road and Pavilion-Clinton Road.

A separate Thompson-Nicola Regional District Evacuation Order applies to Downing Provincial Park and associated affected property.

Nearby TNRD properties remain under Evacuation Alert.

The latest verified local update lists Pear Lake at approximately 30 hectares.

Pavilion-Clinton Road is closed through the Evacuation Order area, and access restrictions are in place to prevent travel into the affected zone.

The Pear Lake portion of Edge Hills Park is also closed.

Ground crews, heavy helicopters and heavy equipment have been assigned, with crews working to establish guard.

Here’s what we’re watching:

• Any expansion of the current Orders

• Escalation of nearby Alert areas

• Changes to Pavilion-Clinton Road access

• Whether guard construction limits further spread

• Effects on rural properties, park facilities or infrastructure

• Coordination with nearby First Nations and regional jurisdictions

Here’s why it matters:

The fire is not large by provincial standards, but it is directly affecting homes, park users and a limited rural access corridor.

The road closure increases operational complexity because evacuation movement and responder access depend on a relatively small number of routes.

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

BRUNSWICK CREEK V10742 — FRASER CANYON

Here’s what we know:

Brunswick Creek remains a Wildfire of Note and continues to affect evacuation planning across the Boston Bar, North Bend, Nahatlatch and Boothroyd corridor.

Multiple Evacuation Orders remain associated with the Brunswick Complex, including areas involving Fraser Valley Regional District communities and First Nations jurisdictions.

The latest available operational reporting indicates steady suppression progress, including a successful planned ignition operation on July 19.

All current Evacuation Orders remained in place in the latest Fraser Valley Regional District update reviewed for this report.

Highway 1 remains open through the broader corridor based on the latest public transportation information reviewed, but wildfire-related traffic control, reduced speed or temporary restrictions may occur with limited notice.

Here’s what we’re watching:

• Whether suppression progress produces a formal change in fire status

• Evacuation Order rescissions or boundary changes

• Heat and wind effects through the canyon

• Highway 1 access and traffic control

• Newly confirmed structure impacts

• Changes affecting Boston Bar First Nation, Boothroyd Indian Band or nearby communities

Here’s why it matters:

Recent suppression progress is meaningful, but the incident remains complex because of steep terrain, multiple jurisdictions, residential losses and the Highway 1 corridor.

Boston Bar is forecast to experience extreme heat over the next several days. High daytime temperatures and warm overnight conditions may increase drying and reduce fuel recovery, although this does not predict renewed fire growth.

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

SOUTH CARIBOO AND BONAPARTE PLATEAU

Here’s what we know:

Multiple wildfire evacuation areas remain active across the South Cariboo and Bonaparte Plateau.

These include ongoing concerns associated with:

• Fiftynine Creek

• Big Bar Lake and Meadow Lake

• South Green Lake

• Bowers Lake

• French Bar Creek

• Pear Lake and the Kelly Lake corridor

The operational pattern remains one of several separate incidents affecting dispersed rural homes, ranches, recreational properties, parks and limited-access roads.

The 100 Mile House area is entering a period of consecutive hot days, with temperatures forecast in the low-to-mid 30s Celsius through Thursday.

Here’s what we’re watching:

• Changes around Big Bar Lake and Meadow Lake

• Rural road access and evacuation-route availability

• Further Order or Alert expansion

• Heat-related increases in afternoon fire behaviour

• Holdover-fire detections from earlier lightning

• Livestock, ranching and recreational-property impacts

• Competition for crews and heavy equipment between nearby incidents

Here’s why it matters:

Rural exposure often involves fewer homes than a city-wide event, but preparation can take longer.

Livestock, private water systems, generators, long driveways and limited road options can all reduce the usefulness of last-minute action.

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

ALBERTA

Here’s what we know:

Alberta continues to list no Wildfires of Note.

The Calgary Forest Area remains under a fire advisory, with very high wildfire danger reported in the latest area update.

Warm temperatures, wind and drying vegetation are increasing the potential for new fires to start and spread quickly. Thunderstorms may produce localized rain, but lightning can also create new ignitions.

Other Alberta forest areas have experienced more variable conditions, including areas where recent precipitation has temporarily reduced wildfire danger.

Here’s what we’re watching:

• Any newly designated Alberta Wildfire of Note

• Lightning-related starts

• Dry thunderstorm or outflow-wind potential

• Changes to Alberta fire advisories, restrictions or bans

• Community, First Nations or infrastructure exposure

• Municipal fires outside the provincial Forest Protection Area

Here’s why it matters:

Alberta’s current operational situation is less significant than British Columbia’s main interface incidents.

However, several consecutive warm days are forecast across southern Alberta, and rainfall from thunderstorms may be uneven. The absence of a Wildfire of Note does not mean the potential for new starts is absent.

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

ENVIRONMENTAL INDICATORS

HEAT AND CONSECUTIVE HOT DAYS

Here’s what we know:

A significant warming period is developing across the Fraser Canyon, South Cariboo and East Kootenay.

Current forecasts indicate:

• Boston Bar may approach or exceed 39°C today and remain extremely hot through Thursday.

• Kimberley is expected to reach approximately 31°C today, with temperatures in the low-to-mid 30s through the end of the week.

• 100 Mile House is expected to reach approximately 33°C today and around 35°C Wednesday and Thursday.

• Calgary is expected to warm progressively through the week.

Here’s what we’re watching:

• Overnight humidity recovery

• Whether smoke moderates daytime heating

• Multiple consecutive days above 30°C

• Fine-fuel drying

• Increased afternoon fire behaviour

• Heat impacts on crews and residents

Here’s why it matters:

Wildfire conditions develop cumulatively.

Several hot days can progressively dry grass, needles, roadside vegetation and surface fuels even where deeper fuels retain some moisture.

These temperatures do not predict fire growth, but they can reduce the margin for error around active incidents and human-caused ignition sources.

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

LIGHTNING AND HOLDOVER-FIRE POTENTIAL

Here’s what we know:

Recent lightning remains operationally relevant in British Columbia, particularly across the Interior and Southeast.

Some lightning-caused fires can remain concealed in forest litter, roots or heavier fuels before becoming visible during warmer and drier afternoon conditions.

Thunderstorms are also possible in parts of Alberta today and later this week.

Here’s what we’re watching:

• Newly detected smoke columns

• Fires appearing several days after a lightning event

• Thunderstorm outflow winds

• Lightning outside the main rainfall area

• New clusters of starts near existing resource commitments

Here’s why it matters:

A newly detected fire may be a delayed discovery rather than a same-day ignition.

That matters operationally because additional starts can emerge while crews are already committed to established incidents.

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

WIND

Here’s what we know:

Light winds have recently supported reduced fire behaviour around Kimberley.

That is favourable, but temporary wind changes remain one of the most important short-term variables across active interface fires.

Here’s what we’re watching:

• Canyon winds around Brunswick Creek

• Valley winds near Kimberley

• Thunderstorm outflows

• Wind shifts near rural evacuation corridors

• Conditions affecting helicopter and fixed-wing operations

Here’s why it matters:

Wind can increase spotting, alter the direction of spread and change which roads or structures are exposed before an updated public perimeter becomes available.

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

RAINFALL AND PROLONGED DRYING

Here’s what we know:

Recent rainfall has been uneven.

Some Alberta forest areas have benefited from meaningful precipitation, while much of southern Alberta and wildfire-relevant Interior British Columbia continues to experience drying conditions.

Scattered thunderstorms later in the week may produce localized rain, but those showers may not reach all active fire areas.

Here’s what we’re watching:

• Duration and amount of rainfall

• Areas repeatedly missed by precipitation

• How quickly fine fuels dry afterward

• Whether rain is accompanied by lightning or gusty winds

Here’s why it matters:

Brief rainfall may dampen grass and exposed fuels without substantially changing deeper fuel moisture or established wildfire perimeters.

Rain should be evaluated locally rather than treated as a regional reset.

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

DROUGHT AND FIRE-WEATHER INDICATORS

Here’s what we know:

Authoritative public Drought Code values were not consistently available at a sufficiently current and local scale for every incident area during this morning’s review.

For that reason, no single Drought Code figure has been carried into this report.

The more reliable current indicators are:

• Consecutive hot days

• Drying fine fuels

• Very high wildfire danger in the Calgary Forest Area

• Active fire behaviour and suppression observations

• Continued open-fire restrictions

• The potential for additional lightning holdovers

Here’s what we’re watching:

• Updated BC fire-danger and weather-station observations

• Changes in overnight recovery

• Extended periods without meaningful rainfall

• Whether hot conditions persist into the weekend

Here’s why it matters:

Avoiding false precision is more useful than publishing an old or geographically distant fire-weather number.

Local weather, fuel condition and operational observations remain the stronger guide.

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

GRASS CURING AND FINE FUELS

Here’s what we know:

Grass, roadside vegetation and other fine fuels can respond quickly to the current heat.

These fuels may ignite and spread rapidly from:

• Vehicles parked over dry vegetation

• Machinery or hot exhaust systems

• Dragging chains or metal

• Campfires and outdoor burning

• Fireworks

• Smoking materials

Here’s what we’re watching:

• Roadside and pasture curing

• Wind-exposed slopes

• Dry vegetation beside homes, decks and fences

• Fine fuels around generators, pumps and equipment

Here’s why it matters:

Fine fuels can carry fire toward heavier vegetation and structures quickly, even when larger fuels remain less receptive.

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

RESTRICTIONS AND HUMAN ACTIVITY

Here’s what we know:

A Category 1 campfire prohibition has been announced for the Southeast Fire Centre beginning at noon Pacific Time on Thursday, July 23.

Category 2 and Category 3 open-fire prohibitions are already in effect across the Southeast Fire Centre.

Category 1 campfires are also prohibited throughout the Cariboo and Kamloops fire centres under current provincial restrictions.

A partial Category 1 prohibition remains in effect within parts of the Coastal Fire Centre.

Alberta’s Calgary Forest Area remains under a fire advisory.

Here’s what we’re watching:

• New or expanded prohibitions

• Municipal or First Nations restrictions that differ from provincial rules

• Preventable roadside ignitions

• Equipment use during hot and windy periods

• Public compliance in high-activity areas

Here’s why it matters:

Preventable human-caused fires compete for the same crews, aircraft and equipment already assigned to lightning-caused and interface incidents.

An activity may still be technically permitted today and prohibited later this week. Conditions and local rules should be checked immediately before proceeding.

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

HOMEOWNER IMPLICATIONS

For residents under an Evacuation Alert:

• Follow the local authority or First Nation that issued it.

• Keep vehicles fuelled and positioned for departure.

• Prepare identification, medication and essential documents.

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

• Confirm available evacuation routes.

• Test pumps, generators and private water systems before they are needed.

• 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 delay to activate sprinklers, move equipment or continue property preparation.

• Do not re-enter closed roads or restricted areas.

For residents outside evacuation areas:

• Monitor official local sources.

• Check road access before travelling.

• Avoid unnecessary ignition-producing activity.

• Do not use smoke direction or unofficial maps as a substitute for evacuation information.

These actions improve readiness. They do not predict wildfire behaviour or guarantee that a structure will survive.

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

WHAT CHANGED SINCE YESTERDAY

Pear Lake produced the most meaningful escalation:

• Evacuation Orders now affect properties in both the Squamish-Lillooet and Thompson-Nicola regional districts.

• Pavilion-Clinton Road is closed through the Order area.

• Edge Hills Park and Downing Provincial Park areas are affected by closures or evacuation measures.

• Surrounding rural properties remain under Alert.

Kimberley remains under city-wide Evacuation Alert, but the latest verified update reported reduced morning fire behaviour, limited growth and improved heavy-equipment access.

Brunswick Creek continues to show meaningful suppression progress, including a successful planned ignition operation, although existing Evacuation Orders remain active.

A new Southeast Fire Centre Category 1 campfire prohibition has been announced and will begin at noon on July 23.

No new Alberta Wildfire of Note was identified in the latest provincial information.

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

WHAT WE’RE WATCHING NEXT

• Any escalation or rescission of the Kimberley Evacuation Alert

• Afternoon fire behaviour on Matthew Creek and Tower Creek

• Pear Lake evacuation and road-access changes

• Brunswick Creek status and Fraser Canyon Order changes

• Highway 1 conditions through Boston Bar

• Heat effects across the Fraser Canyon and South Cariboo

• Additional holdover-fire detections

• Thunderstorm outflow winds

• Progress on heavy-equipment guard construction

• Any new BC or Alberta Wildfire of Note

• Further campfire or activity prohibitions

• Confirmed structure or infrastructure impacts

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

STRUCTURE DEFENCE TAKEAWAY

Here’s what we know:

British Columbia continues to manage several significant wildfire situations involving cities, rural homes, First Nations jurisdictions, parks and restricted road access.

Pear Lake has become more operationally significant because of Evacuation Orders and a road closure.

Kimberley remains the largest current population centre under Evacuation Alert, although recent suppression observations provide some cautious operational encouragement.

Brunswick Creek remains significant, but measurable progress is being made.

Alberta has no designated Wildfire of Note, though wildfire danger remains elevated in parts of the province.

Here’s what we’re watching:

The next meaningful changes will come from heat, wind, afternoon fire behaviour, evacuation-boundary changes, road access and whether current suppression gains can be maintained.

Here’s why it matters:

The wildfire situation is active, but risk remains local.

Most residents in British Columbia and Alberta are not under immediate threat. Those near active incidents should prepare early, follow official instructions and avoid treating broad weather indicators as predictions for an individual property.

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