Fire Danger for the Holiday Week

Cold Water Safety

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 holiday week, this weekend, and into next week. Please keep in mind to stay hydrated and cool.

An Excessive Heat Warning for the San Joaquin Valley, West Side Hills, Sierra Foothills, Yosemite Valley, Kern River Valley, Tehachapi Mountains, and Kern County Desert has been extended through 8 AM PDT Wednesday, July 10, 2024. Please keep in mind to stay hydrated and cool.

Elevated fire danger will be present across California this week due to widespread afternoon temperatures near 110 degrees, minimum relative humidity less than 20%, and dry fuel loads throughout the central valley. Take appropriate measures to mitigate the initiation and spread of grass fires, including foregoing the use of fireworks for the Fourth of July.

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.
