Strong to potentially severe thunderstorms are possible through 9:00p.m. this evening across the eastern Sierra, northeast California and western Nevada.
Strong thunderstorms will produce hail, winds in excess of 40 mph, heavy rain, and a rapid decrease in temperatures. Accumulating hail may occur in the Sierra.
Localized areas of blowing dust will accompany strong outflow winds across the eastern Sierra and western Nevada.
Heavy rainfall may lead to ponding of water on roadways. In areas of steep terrain and near recently burned areas, rock slides and debris flows are possible.
Now is the time to think about a Plan B for all outdoor activities the rest of today. Be aware of thunderstorm activity in your vicinity. Lightning may strike up to 10 miles away from the core of a thunderstorm.
During a thunderstorm, seek shelter inside a sturdy structure and stay away from windows. If on or near a lake, get out of the water and move indoors or inside a vehicle.
Don’t be caught on the water in a thunderstorm. Gusty winds will cause a rapid increase in wave heights which may capsize small boats.
