Lake Tahoe weather: Heavy rain, mudslides, 150 mph winds, 1-3 feet of snow all possible
February 9, 2017
TRUCKEE, Calif. — February's wet and wild start will continue Thursday and into the weekend, with flood warnings and winter storm warnings both on tap.
According to the National Weather Service in Reno, a flood warning is in effect from 6:45 a.m. Thursday through 9:15 a.m. Saturday for lower elevation areas in Placer, Nevada, Washoe and El Dorado counties, as well as other counties.
"Two-day rainfall totals between 5 and 9 inches have been measured in the northern Sierra, bringing river and stream rises across the area," according to the NWS-Reno warning posted Thursday morning. "High river and stream flows in the Sierra, such as the upper portions of the Feather River system, are already occurring and will continue through Saturday."
According to the weather service, while minor flooding is likely to continue at certain parts across the Tahoe-Truckee region, the larger threats for flooding are in the Sierra Foothills and Washoe and Carson valleys, among other lower-elevation areas.
"Widespread moderate to heavy rain will return to northern California today through this evening, tapering to mountain snow showers tonight through Friday," according to NWS. "Despite precipitation ending, high river and stream flows will continue through early Saturday."
Aside from flooding, mudslides are also possible, especially for mountain roads and burn scars.
