Information current as of: 8:30 a.m. Pacific Time
This report summarizes publicly available authoritative information available at the time of publication. Conditions can change rapidly. Always follow instructions issued by your local emergency authority.

OPERATIONAL ASSESSMENT
Today's operational picture is defined by three themes.
• The Fraser Canyon remains British Columbia's highest-priority community wildfire environment. Evacuation Orders now extend across multiple local governments and First Nations jurisdictions, reflecting continued concern for communities and critical transportation infrastructure rather than a single isolated incident.
• Several significant BC wildfires are showing encouraging suppression progress near communities, but evacuation measures remain appropriate. Signal Hill near Pemberton is a good example: crews reported meaningful progress while local authorities continue asking residents to remain prepared.
• Alberta remains comparatively stable from a major-incident perspective. No Wildfires of Note have been declared, although warm weather, thunderstorms and human-caused ignition risk continue to warrant attention.
This is a reminder that wildfire seasons are rarely defined by one statistic. Operational significance comes from how wildfire interacts with people, communities, infrastructure and weather—not simply from hectares burned.
────────────────────────────────────────
WHAT CHANGED SINCE YESTERDAY
Fraser Canyon
The most significant development was the expansion of mandatory evacuation measures around Boston Bar.
The Fraser Valley Regional District upgraded portions of the Boston Bar area from Evacuation Alert to Evacuation Order because of increased activity associated with the Brunswick Creek and Ainslie Creek wildfires.
Boston Bar First Nation also expanded evacuation measures with an Evacuation Order for IR 1 Tuckkwiowhum.
These changes increased the number of communities and jurisdictions now operating under mandatory evacuation.
French Bar Creek
A localized Evacuation Order remains in effect for one isolated property along Lone Cabin Creek while nearby Empire Valley Road properties remain under Evacuation Alert.
No broader community expansion has been confirmed.
Alberta
No new Wildfire of Note, major evacuation escalation or significant transportation impact was confirmed today.

SIGNIFICANT INCIDENT WATCH
Brunswick Creek (V10742) / Ainslie Creek (V10755)
The Fraser Canyon continues to represent the province's most operationally significant wildfire environment.
Confirmed Evacuation Orders remain across multiple Fraser Valley Regional District communities together with several First Nations jurisdictions.
Current public information confirms evacuation measures affecting:
• Boston Bar
• North Bend
• Boothroyd
• Fishblue Lake
• Nahatlatch
• Multiple nearby First Nations reserve lands
Highway access through the Fraser Canyon continues to require travellers to verify current DriveBC information immediately before travel because traffic management can change rapidly as suppression operations evolve.
Why it matters
The significance is no longer simply wildfire growth.
This incident now affects residents, transportation corridors, emergency access and multiple jurisdictions simultaneously.
Signal Hill (Pemberton)
Signal Hill remains Out of Control.
Yesterday's operational updates reported meaningful suppression progress on the portions of the fire closest to Pemberton.
Evacuation Alerts remain in place while firefighters continue strengthening containment near the community.
Why it matters
Out of Control does not necessarily mean uncontrolled.
Communities may remain under Alert while firefighters successfully reduce immediate structure exposure.
French Bar Creek
Localized evacuation measures remain in effect.
At this time no broader expansion of the evacuation area has been confirmed.

ENVIRONMENTAL INDICATORS
Heat
Interior British Columbia remains very hot.
Temperatures near 35–37°C continue across portions of the Thompson and Okanagan.
Repeated days of high temperatures continue drying fine fuels despite localized showers.
Thunderstorms & Lightning
Thunderstorm potential exists today across portions of:
• Thompson-Okanagan
• Alberta foothills
• Northwestern Alberta
The concern is not that every lightning strike becomes a wildfire.
The concern is isolated ignitions and holdover fires that may not become visible until later operational periods.
Wind
Localized thunderstorm outflow winds remain the greatest weather concern today.
Even relatively modest wind changes can significantly influence active fire behaviour.
Rainfall
Scattered showers remain uneven.
One valley may receive useful moisture while neighbouring slopes remain essentially unchanged.
Short-duration rainfall should not be interpreted as ending wildfire potential.
Grass & Fine Fuels
Roadside grasses, cured vegetation and light surface fuels continue to support rapid fire spread where ignitions occur.
These lighter fuels frequently become the pathway that carries fire toward fences, decks, sheds and homes.
Restrictions & Human Activity
Campfire prohibitions remain in effect across several BC fire centres, including the Kamloops Fire Centre and much of Coastal BC.
Residents should always verify restrictions for their specific location before conducting any outdoor burning or spark-producing work.
Human-caused ignitions remain one of the most preventable wildfire risks.
────────────────────────────────────────
HOMEOWNER IMPLICATIONS
Today's conditions continue to favour preparedness over reaction.
This is a good opportunity to:
• Clear combustible debris from roofs, gutters and decks.
• Ensure driveways remain accessible for emergency vehicles.
• Keep evacuation plans current if your property is under Alert.
• Confirm hoses are connected and ready for use for small spot fires only.
• Avoid parking hot vehicles on cured grass.
• Delay unnecessary spark-producing activities during the hottest part of the day.
Preparedness reduces vulnerability but should never delay evacuation if an Order is issued.
────────────────────────────────────────
WHAT WE'RE WATCHING NEXT
• Any expansion or reduction of evacuation areas around Brunswick Creek and Ainslie Creek.
• Verified changes in fire behaviour or operational status in the Fraser Canyon.
• Highway 1 access through the Fraser Canyon.
• Overnight suppression progress at Signal Hill.
• Any expansion of evacuation measures near Pemberton.
• Further developments at French Bar Creek.
• New lightning-caused starts following today's thunderstorms.
• The return of sustained Interior heat early next week.
• Any new Alberta Wildfire of Note or significant evacuation event.
