OPERATIONAL ASSESSMENT

MULTIPLE OKANAGAN EVACUATION EMERGENCIES REMAIN THE LEADING OPERATIONAL CONCERN AS A SIGNIFICANT HEAT EVENT BUILDS

Here’s what we know:

The most operationally significant wildfire activity remains concentrated in the Okanagan, where the Quilpituk Creek and Bradley Creek wildfires continue to affect multiple communities, First Nations jurisdictions and constrained transportation corridors.

Along Westside Road, multiple Evacuation Orders and Alerts remain associated with the Quilpituk Creek wildfire.

The evacuation environment includes communities and properties around:

• Caesars Landing

• Killiney Beach

• Lower Fintry

• Valley of the Sun

• Ewings Landing

• La Casa

• Areas extending north toward the Okanagan Indian Band boundary

Westside Road access remains restricted in the active evacuation area. Residents must follow the current traffic-control and evacuation directions issued by emergency officials.

In the North Okanagan, Evacuation Orders and Alerts associated with the Bradley Creek wildfire remain active across Okanagan Indian Band, Splatsin First Nation, the Township of Spallumcheen and neighbouring Columbia Shuswap Regional District areas.

Elsewhere:

• The Riley Creek Evacuation Alert was expanded Monday across portions of the Thompson-Nicola Regional District.

• Multiple Orders and Alerts remain associated with the Pear Lake and wider Big Bar wildfire environment.

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

• Yale First Nation remains under Evacuation Alert.

• Alberta continues to list no Wildfires of Note.

Here’s what we’re watching:

• Further changes along Westside Road

• Whether Quilpituk Creek or Bradley Creek affects additional communities or transportation routes

• Changes involving Okanagan Indian Band, Splatsin and neighbouring local governments

• Riley Creek evacuation boundaries

• Pear Lake and South Cariboo evacuation changes

• Highway 1 reopening criteria through the Fraser Canyon

• Fire behaviour during the heat expected Wednesday through Friday

Here’s why it matters:

The current wildfire environment combines active evacuations, First Nations jurisdictions, rural properties and limited-access transportation corridors.

The approaching heat may increase fire activity and reduce overnight recovery, but it does not predict where an incident will spread or whether an evacuation boundary will change.

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

TODAY’S CONDITIONS

CENTRAL OKANAGAN — QUILPITUK CREEK AND WESTSIDE ROAD

Here’s what we know:

Multiple Evacuation Orders and Alerts remain active along the Westside Road corridor due to the Quilpituk Creek wildfire.

The affected corridor includes year-round homes, seasonal properties, resorts, campgrounds and rural communities with limited alternate access.

Westside Road remains subject to emergency access controls in the evacuation area. Residents and travellers should not enter restricted sections unless directed by officials.

The Kelowna area is forecast near 31°C today, followed by approximately:

• Wednesday — 35°C

• Thursday — 37°C

• Friday — 38°C

• Saturday — 35°C

Haze and wildfire smoke are expected to continue affecting visibility and air quality.

Here’s what we’re watching:

• Additional Evacuation Orders or Alerts

• Westside Road access and traffic movement

• Structure, resort and campground exposure

• Power, communications and private-water reliability

• Overnight humidity recovery

• Fire behaviour during Thursday and Friday’s peak heat

Here’s why it matters:

Westside Road is a long, narrow and geographically constrained corridor.

Residents under Order must leave immediately. Residents under Alert should prepare vehicles, medications, pets, livestock and accommodation arrangements before conditions change.

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

NORTH OKANAGAN — BRADLEY CREEK

Here’s what we know:

The Bradley Creek wildfire remains associated with Evacuation Orders and Alerts across several jurisdictions.

Affected authorities include:

• Okanagan Indian Band

• Splatsin First Nation

• Township of Spallumcheen

• Columbia Shuswap Regional District

The CSRD reported Monday that its Evacuation Alerts in Electoral Area D remained unchanged.

The fire previously crossed Westside Road and affected access along Highway 97 near Spallumcheen. Road conditions should be confirmed through DriveBC immediately before travel.

Conditions around Vernon and the North Okanagan are entering a significant warming and drying period through Friday.

Here’s what we’re watching:

• Changes to Okanagan Indian Band and Splatsin evacuation information

• Spallumcheen and CSRD Orders and Alerts

• Highway 97 and local-road access

• Fire movement toward additional rural or agricultural properties

• Confirmed structure and infrastructure impacts

• Fire activity as temperatures rise

Here’s why it matters:

The Bradley Creek response involves overlapping jurisdictions and a mix of reserve lands, farms, acreages and transportation routes.

Residents must follow the emergency authority responsible for their exact location rather than relying on a single regional description.

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

LILLOOET AND THOMPSON-NICOLA — RILEY CREEK

Here’s what we know:

The Thompson-Nicola Regional District expanded its Riley Creek Evacuation Alert at noon Monday.

The expanded Alert replaces the previous TNRD Alert and affects additional properties in the broader Riley Creek wildfire environment.

The District of Lillooet itself is not currently listed as being under Evacuation Order or Alert.

T’it’q’et First Nation previously rescinded its Evacuation Orders for Towinock IR 2 and Kilchult IR 3. However, evacuation information remains active in neighbouring jurisdictions.

Lillooet is forecast near 34°C today, rising to approximately:

• Wednesday — 37°C

• Thursday — 39°C

• Friday — 38°C

• Saturday — 34°C

Here’s what we’re watching:

• Any upgrade from Alert to Order

• Texas Creek and rural-road access

• Fire activity during consecutive days above 30°C

• Overnight humidity recovery

• Agricultural, utility and communications exposure

• Additional First Nations evacuation information

Here’s why it matters:

The expanded Alert indicates that emergency officials continue to see sufficient potential risk to warrant broader preparation.

Residents under Alert should use the available time to prepare rather than waiting for visible fire activity or heavy smoke.

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

PEAR LAKE, BIG BAR AND THE SOUTH CARIBOO

Here’s what we know:

The Pear Lake wildfire remains operationally significant across the South Cariboo and Thompson-Nicola regions.

Multiple Evacuation Orders and Alerts remain associated with communities and rural areas around:

• 70 Mile House

• Green Lake

• Loon Lake

• Big Bar

• Meadow Lake

• Highway 97

• Several rural and forest service roads

Public incident-size information has not been updated consistently enough to justify presenting an older figure as a precise current perimeter.

Approximately 500 wildland and structural firefighters were reported working within the wider Pear Lake response over the weekend.

The Cariboo Regional District has rescinded some evacuation areas as conditions allowed, while other Orders and Alerts remain active.

Temperatures around 70 Mile House are forecast near:

• Today — 30°C

• Wednesday — 35°C

• Thursday — 36°C

• Friday — 36°C

Here’s what we’re watching:

• Changes around Green Lake, 70 Mile House and Loon Lake

• Highway 97 and rural-road access

• Officially confirmed structure impacts

• Livestock and agricultural movement

• Power and communications reliability

• Fire response during the four-day heat period

Here’s why it matters:

The South Cariboo remains a large, multi-jurisdictional wildfire environment.

Evacuation boundaries and verified community impacts are currently more operationally useful than an older fire-size estimate.

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

FRASER CANYON — BOSTON BAR, NORTH BEND, HELLS GATE AND YALE

Here’s what we know:

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

The northbound closure begins near Yale. Travellers are being directed toward alternate routes through Highway 3 or Highway 5.

Yale First Nation remains under Evacuation Alert.

Multiple Evacuation Orders and Alerts also remain associated with communities and First Nations jurisdictions farther north in the Fraser Canyon.

Operational concerns continue to include:

• Highway access

• Rail infrastructure

• Water-system reliability

• Power and communications

• Falling fire-damaged trees

• Slope instability and rockfall

• Emergency-service access

Boston Bar is forecast near:

• Today — 35°C

• Wednesday — 38°C

• Thursday — 39°C

• Friday — 38°C

• Saturday — 34°C

Here’s what we’re watching:

• Highway 1 reopening criteria

• Changes to Yale, Boston Bar and North Bend evacuation information

• Water and communications reliability

• Rail and utility exposure

• Falling-tree and slope hazards

• Fire behaviour during consecutive days of extreme heat

Here’s why it matters:

This remains an access and infrastructure emergency as well as a wildfire incident.

Reduced visible fire activity would not automatically make the highway safe. Fire-damaged trees, unstable slopes, smoke and limited emergency access may continue to delay reopening.

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

ALBERTA

Here’s what we know:

Alberta currently lists no Wildfires of Note.

The most recently published provincial forest-area updates do not identify a major community-threatening incident.

Conditions around Rocky Mountain House are comparatively moderate, with forecast highs near:

• Today — 24°C

• Wednesday — 24°C

• Thursday — 20°C

• Friday — 23°C

Thunderstorms become more possible Friday and through the weekend.

Wildfire danger and restrictions remain location-specific across Alberta. A lack of Wildfires of Note does not mean all forest areas, municipalities or parks have the same conditions.

Here’s what we’re watching:

• New lightning-caused starts later this week

• Areas receiving lightning without meaningful rainfall

• Holdover fires emerging after afternoon heating

• Fire Advisory, Restriction or Ban changes

• Municipal incidents outside the Forest Protection Area

• Human-caused starts in cured grass

Here’s why it matters:

Alberta’s current operational picture remains quieter than British Columbia’s.

However, localized ignition potential continues where dry fine fuels, lightning or human activity are present.

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

ENVIRONMENTAL INDICATORS

SIGNIFICANT MULTI-DAY HEAT

Here’s what we know:

A significant heat event is developing across much of southern and central British Columbia.

Forecast highs through Friday include approximately:

• Kelowna — 31°C today, rising to 38°C Friday

• Lillooet — 34°C today, rising to 39°C Thursday

• Boston Bar — 35°C today, rising to 39°C Thursday

• 70 Mile House — 30°C today, rising to 36°C Thursday and Friday

Several active-fire regions may experience five or more consecutive days at or above 30°C.

Poor overnight humidity recovery may become increasingly important where nighttime temperatures remain elevated.

Here’s what we’re watching:

• Fine-fuel drying

• Overnight humidity recovery

• Increased afternoon fire activity

• Heat stress affecting firefighters and evacuees

• Smoke production and air quality

• Whether established guards and control lines continue to hold

Here’s why it matters:

Consecutive hot days can rapidly dry grass, needles, bark and other exposed fuels.

Heat identifies conditions that may support increased fire activity. It does not predict that an evacuation will occur or that a structure will be lost.

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

RAINFALL, PROLONGED DRYNESS AND FIRE-WEATHER INDICATORS

Here’s what we know:

The weekend brought localized showers and cooler conditions to portions of southern British Columbia.

The rainfall was not sufficiently widespread or sustained to describe the broader wildfire environment as having reset.

The current forecast is predominantly hot and dry across priority British Columbia regions through Friday.

Current authoritative public information does not provide one province-wide Drought Code value that accurately represents all affected regions. Fire-weather conditions vary by station, elevation and fire centre.

Here’s what we’re watching:

• Areas that received little measurable weekend rainfall

• Rapid drying of temporarily wetted grass and surface fuels

• Deeper fuel moisture and persistent seasonal dryness

• Local fire-weather indices issued by BC Wildfire Service

• Overnight humidity recovery

• Any isolated rainfall that fails to provide sustained wetting

Here’s why it matters:

A short shower may temporarily moderate fine fuels without materially changing larger dead fuels, organic layers or seasonal dryness.

Rainfall should be assessed by amount, coverage and duration rather than by the presence of rain alone.

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

WIND

Here’s what we know:

Heat is the dominant regional weather signal today.

Localized valley, slope and lake winds remain important around Westside Road, the North Okanagan, Lillooet and the Fraser Canyon.

Terrain-driven wind can differ substantially from broad regional forecasts.

Here’s what we’re watching:

• Afternoon valley and lake winds

• Wind direction relative to evacuation routes

• Spotting across roads, lakeshore corridors or control lines

• Smoke affecting visibility

• Falling trees and power interruptions

• Areas where wind overlaps with the lowest humidity

Here’s why it matters:

Local wind can change wildfire behaviour quickly, particularly in narrow valleys, steep drainages and constrained lakeshore corridors.

Temperature alone does not describe the full fire-weather environment.

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

LIGHTNING AND HOLDOVER-FIRE POTENTIAL

Here’s what we know:

Widespread lightning is not the primary concern across southern British Columbia today.

Holdover fires from previous lightning may become more visible as temperatures rise and surface fuels dry.

Thunderstorm potential becomes more relevant across portions of Alberta later this week.

Here’s what we’re watching:

• New smoke during afternoon heating

• Fires appearing several days after lightning

• Clusters of new starts

• Lightning occurring outside meaningful rainfall

• Ignitions near communities, highways or evacuation routes

• Competition for Initial Attack resources

Here’s why it matters:

Lightning-caused fires can remain concealed in duff, roots and heavier fuels before becoming visible.

A lack of smoke immediately after a storm does not confirm that no ignition occurred.

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

GRASS CURING AND HUMAN ACTIVITY

Here’s what we know:

Grass, roadside vegetation and other exposed fine fuels are increasingly receptive to ignition.

Long-weekend visitors are now travelling home, increasing highway traffic through parts of British Columbia already affected by wildfire, detours and restricted access.

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

• Traffic congestion near evacuation routes

• Visitors entering restricted fire areas

• Compliance with prohibitions and restrictions

Here’s why it matters:

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

Preventable incidents also draw crews and aircraft away from communities already affected by wildfire.

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

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 in northern British Columbia remain more location-specific following recent partial rescindments.

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

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

Here’s what we’re watching:

• New restrictions associated with the developing heat

• Local restrictions that exceed provincial requirements

• Alberta Fire Advisory, Restriction or Ban changes

• Human-caused activity following the long weekend

• Whether sustained drying leads to additional prohibitions

Here’s why it matters:

Restrictions apply by specific location and activity type.

A restriction being reduced in one part of a province does not change prohibitions elsewhere.

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

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 official instructions regarding pets, livestock, trailers and restricted roads.

For residents under Evacuation Alert:

• Confirm whether your exact property is inside 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 while time and conditions allow.

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

For residents returning after an Order is rescinded:

• Continue monitoring the responsible emergency authority.

• Restore hoses, pumps, generators and emergency supplies to a ready condition.

• Expect smoke, emergency vehicles and ongoing suppression activity.

• Do not enter restricted areas or interfere with firefighting operations.

For residents outside evacuation areas:

• Verify local restrictions before outdoor work or recreation.

• Remove dry debris from decks, gutters and the immediate area beside structures.

• Avoid parking or operating hot equipment in dry grass.

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

• Account for smoke, detours and changing road access when making travel plans.

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

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

WHAT CHANGED SINCE YESTERDAY

The most significant new development:

• The Thompson-Nicola Regional District expanded its Riley Creek Evacuation Alert at noon Monday.

Continuing Okanagan evacuation concerns:

• Multiple Quilpituk Creek Evacuation Orders and Alerts remain active along Westside Road.

• Bradley Creek evacuation areas remain active across Okanagan Indian Band, Splatsin First Nation, Spallumcheen and the Columbia Shuswap Regional District.

• Multiple Pear Lake and South Cariboo evacuation areas remain active.

• Highway 1 remains closed north of Hells Gate.

• Yale First Nation remains under Evacuation Alert.

• Multiple Fraser Canyon Orders and Alerts remain active.

• Alberta continues to list no Wildfires of Note.

Environmental change:

• The weekend’s cooler weather has ended across most priority British Columbia regions.

• A significant multi-day heat event begins today and intensifies through Thursday and Friday.

• Kelowna, Lillooet, Boston Bar and 70 Mile House are forecast to experience several consecutive days above 30°C.

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

WHAT WE’RE WATCHING NEXT

• Quilpituk Creek evacuation boundaries

• Westside Road access and traffic movement

• Caesars Landing, Killiney Beach, Fintry and La Casa evacuation status

• Bradley Creek evacuation changes

• Okanagan Indian Band and Splatsin emergency information

• Highway 97 access near Spallumcheen

• Overnight humidity recovery

• Holdover-fire detections

• Newly affected communities or First Nations jurisdictions

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

• Alberta wildfire-danger and restriction changes

• Any prohibition scheduled to take effect within the next 72 hours

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

STRUCTURE DEFENCE TAKEAWAY

Here’s what we know:

The continuing Quilpituk Creek and Bradley Creek evacuation emergencies remain today’s leading operational concern.

Both incidents affect multiple jurisdictions, rural properties and transportation routes where access can become as important as the wildfire perimeter itself.

The Riley Creek Evacuation Alert expanded Monday, while Pear Lake and the Fraser Canyon remain operationally significant.

Highway 1 remains closed north of Hells Gate.

Alberta continues to report no Wildfires of Note.

A significant heat event is now developing across southern British Columbia, with several active-fire regions forecast to experience multiple consecutive days above 30°C.

Here’s what we’re watching:

The next meaningful developments will involve evacuation boundaries, transportation access, overnight humidity recovery and how active fires respond during Thursday and Friday’s peak heat.

Here’s why it matters:

Wildfire conditions remain uneven and location-specific.

An unchanged evacuation boundary does not mean an incident is resolved, and rising temperatures do not mean escalation is inevitable.

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

Wildfire resilience starts before wildfire arrives.
