There is a slight (15-20 percent) chance of afternoon and evening thunderstorms from Yosemite NP to Sequoia NP, mainly in the higher elevations of the Sierra Nevada. Frequent dangerous lightning, brief heavy rain, small hail, and gusty, erratic winds are all possible with any thunderstorm that develops. When thunder roars, go indoors!
Rivers and streams continue to flow cold and fast! Here are some safety tips if venturing outdoors, especially near cold water.
Heat Related Deaths are Preventable! Look before you lock! The temperature inside a vehicle can quickly become dangerous. With an outside temperature of only 80 degrees, the inside of a vehicle can rise well above 100 degrees within 20 minutes and above 120 degrees within an hour!
