Two active wildfires are burning in the far eastern reaches of Whatcom County near Ross Lake, while a county-wide Stage 2 burn ban remains in place and a significant weather pattern shift is expected to bring rain and thunderstorms to the region by Saturday morning, according to the Whatcom County Sheriff's Office Division of Emergency Management briefing released Thursday, August 20.
The Emergency Operations Center is not currently activated, but county officials say they are closely monitoring conditions and remain in contact with incident management teams working both the Border 2 Fire and the Ptarmigan Fire through the North Cascades National Park Service. Whatcom County has no direct involvement in active suppression operations on either fire.
The Fires Near Ross Lake
The Border 2 Fire, Whatcom County's largest active wildfire this season, is burning across just over 17,000 acres northeast of Ross Lake. The majority of the blaze is in Canada, with nearly 7,300 acres on the U.S. side. As of Thursday, crews had achieved 43 percent containment, a meaningful improvement from earlier in the week. Full containment is not expected until November.
Just west of Ross Lake, the Luna Fire has seen minor growth and is now burning roughly 4,500 acres with still no containment. Like the Border 2 Fire, the Luna Fire is not expected to be fully contained until fall. Much of Washington state's firefighting resources remain committed to larger blazes in Chelan and Okanogan counties, limiting the reinforcements available for Whatcom County operations.
The Washington Department of Natural Resources fire danger level for Whatcom County lowlands is currently rated Very High, with the Cascades also at Very High. The entire county remains under a drought declaration issued by the Washington Department of Ecology in April 2026, and the U.S. Drought Monitor shows most of the county as abnormally dry, with far eastern portions in moderate drought.
Stage 2 Burn Ban: What That Means
A Stage 2 burn ban has been in effect county-wide since 0800 on July 17 and remains active until further notice. Under Stage 2 restrictions, all open burning is prohibited with no exceptions for recreational fires or yard debris. Residents who violate burn ban rules can face significant fines. Anyone unsure whether a specific activity is permitted should check current regulations at whatcomcounty.us before lighting anything outdoors.
Air quality across the county is currently rated Good, a positive note during a period when wildfire smoke has periodically degraded conditions. Residents can monitor current air quality through the Northwest Clean Air Agency, which provides real-time readings for monitoring stations across Whatcom County including Bellingham, Lynden, and Birch Bay.
Weekend Weather: Rain and Thunderstorm Risk Arriving Saturday
The weather pattern is about to shift significantly after weeks of dry, warm conditions. Thursday was sunny after morning fog cleared in some areas, and Friday will remain dry through most of the day. However, a disturbance moving in from the south late Friday afternoon and evening introduces a threat of developing rain showers and thunderstorms through midnight before conditions dry out briefly overnight.
The main frontal boundary arrives Saturday morning, bringing frequent rain showers and thunderstorms through the afternoon and into the evening. Emergency managers are warning of potential brief heavy downpours, lightning strikes, and breezy outflow winds during Saturday's storm activity. Showery weather continues into Sunday before clearing by Sunday evening. Dry weather is then expected to hold into next week, though a weak shortwave trough could produce a few showers Tuesday afternoon.
For boaters and those spending time on the Strait or inland coastal waters, forecasters expect northwest winds at 5 to 10 knots Thursday into Friday, with wind waves around two feet or less. Saturday's frontal passage will bring a weak surface low and associated front through the area before high pressure rebuilds Sunday through Monday. Real-time coastal weather and tide data is available through the Cherry Point NOAA Tide Station.
Staying Ready: Sign Up for Emergency Alerts
Whatcom County Emergency Management urges all residents to make sure they are signed up for WhatcomReady emergency alerts, which provide direct notification for incidents that could affect specific neighborhoods including evacuation orders, road closures, and public safety emergencies. Residents can sign up through the WhatcomReady portal at whatcomcounty.us.
Community Emergency Response Team training is ongoing for residents who want to build hands-on emergency preparedness skills. The CERT program equips community members to assist their neighbors during disasters when professional responders are overwhelmed or delayed. Information on upcoming CERT classes is available through the county's emergency management division.
Looking ahead, the arrival of Saturday rain could briefly reduce active fire behavior on both the Border 2 and Luna fires, though emergency managers note that neither is expected to see significant containment gains until consistent fall precipitation patterns establish themselves.
