The duration of this heat wave, which began on Sunday, and the high overnight temperatures are creating problems across the region.
Temperatures will remain above average through Thursday, with excessive heat warnings lasting through Wednesday.
The dangerous heat wave will continue as a strong ridge of high pressure remains in place, with most of the region under heat-related advisories and warnings. High temperatures will be in the 90s around Puget Sound. Overnight lows will remain warm.

These temperatures, combined with the duration of heat that is expected to continue through this week, will increasingly pose a heightened health risk, especially for those without adequate air conditioning.
KIRO 7 meteorologist Nick Allard said temperatures in the 90s and high 80s will continue through Thursday. Much cooler on Friday and through the weekend, with highs in the 70s. Sunny skies will continue.
