Overview
- The warning runs from 1 to 9 a.m. PST Friday for interior Monterey and San Benito counties and the eastern Santa Clara Hills after an upgrade from a watch using newly adopted NWS cold-impact alerts.
- Forecast lows of 25–32°F will bring freezing conditions and frost, posing hypothermia risks for unsheltered people and threats to livestock and sensitive crops.
- A Cold Weather Advisory covers adjacent areas including the East Bay hills and valleys, Santa Cruz Mountains, Santa Clara Valley, North Bay interior valleys, and coastal zones from Monterey Bay to Big Sur, with lows in the low to mid-30s and widespread frost.
- Officials urge residents to dress in layers, use heaters safely, avoid indoor use of generators or grills, check local warming centers, and protect pets, livestock, and plants.
- Hazardous beach conditions with large surf will continue to produce dangerous rip currents, sneaker waves, and minor high-tide flooding, with the coldest mornings expected Friday on the Central Coast and Saturday in the Bay Area before a gradual warmup next week into the upper 60s to low 70s.
