What the forecasts say: heat and fire watches

The National Weather Service has issued a fire weather watch beginning Thursday afternoon and evening (Aug. 21), followed by an extreme heat watch from Aug. 22 through Aug. 24.

Temperatures are expected to hover near or above 95°F for a stretch of three to five days, with a slightly cooler Thursday high forecast near 90°F.

Low overnight and daytime humidity combined with persistent north winds of 5–10 mph and gusts up to 21 mph will elevate wildfire spread potential, even though the winds are not exceptionally strong.

These ingredients—heat, dryness and gusty winds—create the classic recipe for rapidly spreading fires.

Why the fire weather watch matters

Fire weather watches are not forecasts that new fires will start, but alerts that the atmosphere will be favorable for existing ignitions to grow quickly.

As meteorologist Treena Jensen notes, these watches are precautionary: they warn communities, land managers and homeowners to reduce ignition sources and be prepared to respond if a fire starts.

Health risks and recommended precautions

The Oregon Health Authority warns that prolonged high temperatures can cause serious heat-related illness, particularly among older adults, young children, people with chronic health conditions, and anyone without reliable air conditioning.

Knowing the early signs and using simple cooling tactics can prevent emergencies.

Watch carefully for symptoms of heat-related illness and act quickly if they appear.

Recognize symptoms and simple cooling strategies

Common signs to monitor include dizziness, nausea, muscle cramps and excessive fatigue.

If someone shows signs of heat stroke—confusion, loss of consciousness, or very high body temperature—call emergency services immediately.

Stay hydrated: Drink water frequently, even if you don’t feel thirsty.

Stay cool inside: Remain in air-conditioned spaces when possible; public cooling centers may be available.

Use fans wisely: Fans help with comfort but aren’t a substitute for air conditioning in extreme heat.

Manage windows: Keep windows closed during the hot daytime hours and open them at night to flush heat, unless wildfire smoke has degraded air quality.

Check on neighbors: Regularly check vulnerable friends and neighbors, especially those without AC or limited mobility.

Wildfire prevention and practical steps for residents

The Oregon Department of Forestry and local officials are emphasizing daily precautions to reduce human-caused ignitions during these critical days.

Simple actions at homes and campsites can markedly reduce risk.

Key prevention tips from the Oregon Department of Forestry

Avoid debris burning and other open flames while the watch is in effect.

Secure tow chains and other equipment that might create sparks on roads or trails.

Ensure campfires are fully extinguished—drown, stir and feel embers to confirm coldness—before leaving a site.

Looking ahead: relief and continued vigilance

Forecast charts suggest some relief may arrive the week after the watches. Possible showers and thunderstorms could begin Aug. 26.

While rain would lower temperatures and help dampen fuels, thunderstorms can produce lightning that ignites new fires. Vigilance should continue.

Prepare now and follow public advisories. Plan for both heat and smoke scenarios so you and your community stay safe.
