Temperatures are expected to reach dangerous levels across the San Joaquin Valley, West Side Hills, Sierra Foothills, Yosemite Valley, Kern River Valley and Kern County Deserts through the week. Please keep in mind to stay hydrated and cool.
The Excessive Heat Warning will remain for Yosemite Valley locations through this week, ending Sunday morning. A Heat Advisory is in effect for the highest elevations of Yosemite National Park since temperatures are well above normal and many of these locations do not have air conditioning.
20-30% Probability of thunderstorms and dry lightning, from Saturday through Sunday night. Less than a 20% Probability of a wetting rain. Highest Probability today and Sunday. Erratic wind gusts 40 to 50 mph in thunderstorm outflow which allows rapid fire spread. Minimum daytime humidity levels 15% or less. Outdoor burning is not recommended.
Warm air temperatures do not mean warm water temperatures. Cold water can very quickly remove heat from the body and lead to a loss of movement in the limbs. When heading into rivers and streams, always take precautions such as wearing a life vest, bringing a life preserver with you, and following all river/stream closures.
