The National Weather Service (NWS) San Francisco has issued a Major Extreme Cold Warning effective from 3:06 AM PST on February 21, 2026, until 9:00 AM PST, targeting Eastern Santa Clara Hills; Southern Salinas Valley/Arroyo Seco and Lake San Antonio; Santa Lucia Mountains and Los Padres National Forest; and Mountains of San Benito County and Interior Monterey County.

What It Means For You: - Immediate Safety: Avoid outdoor activities; if outside, cover all exposed skin, limit time to under 30 minutes, and watch for hypothermia signs like shivering, confusion, or numbness—seek warm shelter immediately. - Travel Disruptions: Expect hazardous road conditions on routes like CA-152, US-101 mountain passes, and forest access roads; check Caltrans QuickMap for closures and delay non-essential travel until after 9 AM PST. - Daily Life Impacts: Power outages possible in remote areas due to wind; prepare with backup heat sources, fully charged devices, and non-perishable food—schools and businesses in affected counties may close. - Economic Notes: Short-term hits to agriculture in Salinas Valley (lettuce/veggie hub) and forestry ops in Los Padres; monitor commodity prices if you're in agribusiness. - Resources: NOAA Weather.gov for live updates; call 211 for local assistance; Red Cross app for hypothermia kits; follow @NWSBayArea on X.
