A Heat Advisory will come into effect Saturday and Sunday across the Sonoma Coastal Range, North Bay interior mountains, the San Francisco Bay Shoreline, the East Bay and South Bay, the Santa Cruz Mountains, the Santa Lucia range, the southern Salinas Valley, and the interior mountains of Monterey and San Benito Counties. Inland highs in the middle 90s to near 103 can cause heat-related illnesses if outdoors for long periods, especially with physical exertion, and mild overnight lows from the upper 60s to middle 70s in the higher elevations will limit overnight recoveries. Drink plenty of water or sports drinks, shift outdoor activities to cooler times of the day, take frequent breaks in air conditioned spaces or the shade, and never leave people or pets in unattended vehicles!
🌊 COASTAL FLOOD ADVISORY EXTENDED THROUGH 6 PM FRIDAY 🌊The Coastal Flood Advisory for low-lying bayshore areas along San Francisco Bay, San Pablo Bay, and Monterey Bay has been extended through 6 PM PDT Friday. What: Up to 0.9 feet of minor inundation above ground level in low-lying shoreline areas and tidal waterways. Tide Peaks: Peak high tides around San Francisco are expected near 3:58 PM Friday (0.9 ft above normal), enhanced by up to 0.7 ft of storm surge. Peak tide times vary up to 90 minutes earlier or later across the region. Impacts: Minor flooding of lots, parks, coastal trails, and low-lying roads, along with isolated road closures. High tides may block access to some beaches and push waves further up shore than usual.
