SOUTH LAKE TAHOE, Calif. – The National Weather Service has issued a flash flood warning for the greater Lake Tahoe area beginning at 1 p.m. and lasting through 8 p.m. today.
According to the NWS abundant moisture and strong instability over the area will allow showers and thunderstorms to produce heavy rain today. The stronger storms may produce rainfall rates of at least one inch per hour and bring the potential for flash flooding.
The greatest risk for flash flooding are locations near small creeks and streams, canyons, steep terrain and urban areas.
Heavy rain may quickly flood dry creeks, wash out roads and create rock slides.
