Isolated thunderstorms will pop up near the Sierra crest during the afternoon hours each day through Tuesday. In addition to dangerous cloud to ground lightning, a few thunderstorms may bring small hail, briefly heavy rain and strong, gusty winds. Hikers in the high country of the Sierra should keep a watchful eye on the sky each afternoon and be prepared to seek shelter if they hear thunder.
As inviting as rivers look on a hot Summer day, they carry hidden dangers. The currents in them are swift and can carry a swimmer quickly downstream into rocks and vegetation within the river channel. Water temperatures are cold enough to lower body temperatures to unsafe levels and can render a swimmer unconscious. Don’t let a river claim you as Its next drowning victim!
