SEATTLE – The National Weather Service issued an Excessive Heat Warning that will be in effect for the Puget Sound area and much of Western Washington Friday and Saturday.
The warning means temperatures are forecast to rise into the upper 80's to mid 90's, and those who are sensitive to the heat should use caution when outdoors. Authorities suggest people check on older relatives and neighbors as the heat persists.
A Red Flag Warning is also in effect for parts of the state through Saturday evening. Low humidity, high temperatures and occasionally gusty winds are combining to create a critical fire hazard where fires may start and spread easily. A statewide burn ban is in effect.
A strong ridge will develop over the Northwest region, increasing temperatures to near record levels. Air flowing down the west slopes of the Cascades will intensify the heat today, especially west of Snoqualmie Pass. The warmest temperatures will be felt near the foothills and over southwest Washington.
The high heat will even make it out along the coast. Below is a shot of temperatures at 5 p.m. Thursday. A high resolution Futurecast model from the University of Washington shows highs in the low to mid 90's Friday and Saturday. A shift to onshore winds will begin late Saturday and will cool the daytime temperatures by 10-15 degrees over Puget Sound on Sunday and even more along the coast.
Overall, it should make for a great weekend to hit the water! See current lake buoy temperatures.
The City of Seattle is providing information and public spaces that may be used by residents to stay cool in the high temperatures.
