Gusty winds, low humidity prompt Red Flag warning for Lake Tahoe and Sierra

A Red Flag warning has been issued by the National Weather Service in Reno until 10 p.m. Thursday night for the Lake Tahoe Basin, Eastern Sierra and Western Nevada. Low pressure associated with a jet stream will pass over the Sierra today producing low humidity and gusty winds to 40 mph across Northeast California, the Lake Tahoe Basin and the Eastern Sierra. The combination of law humidity and wind will create critical fire conditions, according to the weather service.
A Lake Wind Advisory has also been issued for Lake Tahoe, with wave heights increasing 2-3 feet from mid lake to downwind shores from Incline Village to Zephyr Cove.
Periods of gusty winds are possible Friday through Sunday as an area of low pressure remains off the Northern California Coast.
