There are no watches, warnings, or advisories at this time.

The threat of isolated afternoon and early evening thunderstorms will continue each day through Wednesday over the higher elevations of the Sierra Nevada. The thunderstorm threat will expand into the Sierra Foothills and the Kern County Mountains today and Tuesday. In addition to cloud to ground lightning, thunderstorms can bring strong, gusty winds and locally heavy downpours. Hikers and campers should keep a watchful eye on the sky the next several afternoons and be prepared to move to a place of safety when you hear thunder.
A weak area of Low Pressure will move through the region this weekend. While it will mean a nice cool down for the people living in the San Joaquin valley and foothills, it could mean a dusting to a couple inches of snow in the Sierra Nevada. The main concern will be along Highway 120 through Yosemite above 7000 feet. This road tends to get busy as soon as it opens for the season, especially during a Holiday weekend. Motorists are advised to prepare for winter-like conditions, slower than normal traffic and possible road closures. Check with Caltrans for current road conditions at (800) 427-ROAD and continue to monitor our webpage at for updates to the forecast.
