Fresno, California – A searing wave of heat will grip the Central Valley Sunday as temperatures soar to 105°F in cities like Fresno, Visalia, and Merced. A Summer Weather Alert remains in place for the San Joaquin Valley, Kern River Valley, and nearby Sierra foothills through 11 p.m. Tuesday, bringing a multi-day risk of heat-related illness.
According to the National Weather Service in Hanford, the heat advisory spans a broad stretch of Central California — including Bakersfield, Los Banos, and Oakhurst — with inland temperatures rising steadily through Sunday and peaking early next week. Cooling centers, shaded parks, and indoor activity are highly encouraged, especially for seniors and outdoor workers. Strenuous activity should be limited to early morning or evening hours.
Roadways like Highway 99 and I-5 may pose danger to stranded drivers with minimal shade and heat radiating from asphalt. Authorities recommend keeping extra water in vehicles and checking tire pressure before travel.
Sunday’s forecast features widespread highs of 102–105°F across valley floors, with slightly cooler conditions in higher elevations like Yosemite Valley and Bass Lake. Overnight lows will stay warm, offering little relief.
