Fourth of July Fire Safety Alert: Dry Fuels and a Holiday Weekend Create Elevated Risk Across the PNW

Fire officials across the Pacific Northwest are urging residents and visitors to exercise exceptional caution this Fourth of July holiday weekend as dry conditions, curing grasses, and the inherent ignition hazards of holiday celebrations combine to create an elevated wildfire risk across much of the region.

Fuels Drying Fast East of the Cascades

According to FOX 13 Chief Meteorologist Brian MacMillan and regional fire weather forecasters, a strengthening high-pressure ridge is settling over Central and Eastern Washington, bringing consecutive dry days and gradually warming temperatures through the weekend. While no widespread lightning events or sustained high-wind episodes are currently forecast, the persistent dry stretch is taking a toll on fine fuels.

Afternoon relative humidity levels are expected to trend lower as the ridge strengthens, with recovery overnight becoming increasingly marginal. The Columbia Basin, Yakima Valley, and Central Washington are considered the highest-concern areas, where cured annual grasses can carry fire rapidly with even a brief wind gust following an ignition.

Fire Restrictions in Effect

Several national forests and BLM field offices across Oregon, Washington, and Idaho have implemented fire restrictions ahead of the holiday weekend. Campers and recreationists should check with their specific destination before lighting any campfire. Key guidance includes:

Campfires are prohibited or restricted in many high-elevation and Eastern Cascades zones
Charcoal and wood fires may be banned in dispersed camping areas even where developed campground fires are permitted
Fireworks are illegal on all federal lands year-round and are prohibited or restricted in many Oregon, Washington, and Idaho municipalities due to fire risk
Sparks from trailers, ATV exhaust, chain saws, and other equipment are a leading cause of human-caused ignitions — check spark arresters and avoid driving over dry vegetation

July 4th: Historically Dangerous

Independence Day is consistently one of the highest human-caused ignition days of the year for the Pacific Northwest. Fireworks, campfires, and celebratory activities push ignition risk to a seasonal peak at a time when fuels are already receptive. Several of the region’s most destructive fires in recent history have started on or immediately after the Fourth of July.

The Washington State Department of Natural Resources notes that the holiday weekend regularly sees a spike in fire starts, many of which occur in the evening hours when ground crews have limited visibility and aerial resources are grounded. Even legal consumer fireworks can throw embers hundreds of feet from the point of ignition.

What You Should Do This Weekend

Check local ordinances before purchasing or using fireworks — even “safe and sane” fireworks are banned in many Oregon and Washington jurisdictions
Never light fireworks near dry grass, brush, trees, or structures
Have a garden hose or bucket of water ready when using any legal fireworks
Fully extinguish campfires — drown, stir, and feel before leaving; if it’s too hot to touch, it’s too hot to leave
Report fires immediately by calling 911 — early detection saves acres and lives
Know your evacuation route and keep your fuel tank at least half full

Agency Readiness

Fire agencies throughout the Pacific Northwest have pre-positioned additional engine crews and dispatchers for the holiday weekend. The Northwest Coordination Center is maintaining elevated staffing through July 6 in anticipation of increased fire starts. Air tanker bases in the region are on higher readiness through the holiday.
