🌡️ While we're expecting a warm weekend & Monday (with moderate risk of heat impacts to those sensitive to the heat), onshore flow is expected to return late Monday night into Tuesday. All locations in western WA will see temperatures drop from Tuesday through the weekend. #wawx
Maximum temperature graphic for several cities in western WA. Highs Saturday through Monday range from the upper 70s to the mid 90s, with areas way from water and mountain tops having the highest temperatures. Cooler temperatures are expected Tuesday through Friday, with more highs in the 70s regionwide. Potential impacts for the weekend & Monday is increased risk of heat related illnesses for those sensitive to heat, or those without adequate cooling or hydration. To take precautions: spend time in air conditioning (when possible), stay hydrated, stay in the shade, reschedule strenuous activities to the morning, wear light clothing, and don't leave kids and pets in closed vehicles.

Going camping? You are NOT safe from lightning in a tent. Avoid standing under trees. Find a sturdy building for shelter. If you can’t find one and are near your hard-topped vehicle, shelter in it with the windows up. weather.gov/safety/lightning
