Seattle, WA – Dangerous heat grips western Washington this week, with Seattle and nearby communities sweltering under an extreme heat warning that lasts until early Wednesday. Temperatures could climb into the upper 80s and 90s Tuesday, raising serious health and travel risks.
According to the National Weather Service, the warning remains in effect through 5 a.m. Wednesday for Seattle, the Eastside, and the lowlands of Pierce and southern King counties. Roadways like Interstate 5 and Highway 99 may see delays as drivers cope with heat-related mechanical issues and reduced air quality.
Residents are urged to stay hydrated, avoid direct sun during the afternoon peak, and check on neighbors, particularly seniors. Young children and pets must never be left in parked vehicles, where temperatures rise dangerously fast.
Cities across the region, including Tacoma, Kent, and Kirkland, will see temperatures hover in the 90s through Tuesday before cooler air arrives midweek. Overnight lows in the mid-60s offer little relief, adding to the strain. Outdoor workers and travelers should take breaks, seek shade, and wear light clothing to reduce risk of heat exhaustion.
The heat eases by Wednesday night, with highs near 84, and more comfortable conditions settling in by Friday. The upcoming Labor Day weekend looks mild, with highs in the 70s and lower humidity—welcomed news for holiday travelers and outdoor events.
Warnings remain in place through Wednesday, and residents should prepare for one more day of extreme heat before relief arrives.
