Western Washington braces for more sizzling temperatures, another high of 90 possible

Seattle and surrounding areas prepare for another scorching day as temperatures are expected to hit the high 80s to low 90s on Sunday. The National Weather Service has issued an extreme heat warning and heat advisory, particularly impacting residents without air conditioning. Saturday evening marked the fifth occurrence this year that Sea-Tac reached 90 degrees or more, with records broken in nearby cities. A red flag warning remains in place for the eastern Olympic Mountains and western Cascades due to high fire danger caused by dry conditions. Monday is projected to maintain similar temperatures, although a slight onshore push may provide some relief.

Residents are advised to stay hydrated and limit outdoor activities to cooler morning or evening hours. As humidity rises mid-week, the potential for showers and thunderstorms increases. The community is reminded to protect vulnerable populations and pets during the heat wave.
