Reno, Nev. – Heavy thunderstorms could trigger flash flooding across northern Nevada and the Sierra Tuesday afternoon, raising concerns for burn scar areas and mountain communities already soaked from days of rain.
According to the National Weather Service in Reno, a Flood Watch is in effect from noon until 9 p.m. Tuesday for the Lake Tahoe Basin, Reno-Carson City-Minden area, Mono County, and portions of Lassen, Plumas, and Sierra counties. Forecasters warned that saturated soils combined with slow-moving thunderstorms could cause creeks and streams to rise quickly, especially in the Tamarack, Mill, and Dixie burn scars.
Residents in South Lake Tahoe, Incline Village, Truckee, and Susanville may encounter road ponding, mudslides near steep terrain, and urban flooding in poor drainage areas. Emergency managers urged drivers to avoid water-covered roads, as even shallow flooding can wash out pavement or conceal debris.
Communities in Smith Valley, Yerington, and Gardnerville are also under threat of flash flooding through this evening, with low-lying areas at greatest risk. The NWS advised residents to stay alert for Flash Flood Warnings that could be issued with little notice.
The Flood Watch expires Tuesday night, but additional storms are possible later in the week.
