LAKE COUNTY, Calif. — Another heat wave arriving this weekend has prompted the National Weather Service to issue an excessive heat warning for Lake and numerous other counties across the state.

The warning is in effect from 2 p.m. Saturday to 9 p.m. Tuesday due to dangerously hot conditions that could reach 110 degrees in Northern California.

The National Weather Service’s forecast said an “exceptionally strong dome of high pressure” that’s persisting over much of the Western United States through next week is bringing the very hot temperatures.

The Lake County forecast anticipates daytime temperatures across the county of 103 degrees on Saturday, 102 on Sunday, 100 on Monday, 102 on Tuesday, 103 on Wednesday and 97 degrees on Thursday.

It will be warm at night, with temperatures forecast to hover in the high 50s and low 60s.

The National Weather Service urges people to take special precautions during this coming heat wave, noting that heat is the leading cause of weather-related fatalities over a 30-year average from 1991 to 2020.

Stay hydrated, don’t stay outdoors for long periods of time and remain in air-conditioned rooms.
