Salinas, CA — A sharp drop in temperatures is prompting new safety advisories for residents, growers, and outdoor workers across inland parts of San Benito and southern Monterey Counties tonight.
Cold Air Mass Brings Unseasonably Low Overnight Temperatures
The National Weather Service in San Francisco has issued a Cold Weather Advisory for the Southern Salinas Valley, Arroyo Seco, Lake San Antonio, and communities near Pinnacles National Park. The advisory will remain in effect from midnight through 8 a.m. Thursday, warning that temperatures may approach levels that pose risks to crops, pets, livestock, and vulnerable residents.
Forecasters say overnight lows are expected to dip to around “34°F”, noting that even slight variations could push some rural pockets down to freezing or below. According to the NWS, “prolonged exposure could result in hypothermia for people and animals”, especially in the coldest interior valleys.
Areas Most Affected by the Advisory
The coldest conditions are expected to settle across inland regions where clearer skies and lighter winds will allow rapid nighttime cooling. Agricultural areas within the Southern Salinas Valley and communities bordering the Gabilan and Santa Lucia mountain foothills are among the most exposed.
Emergency officials emphasize that this cold comes at a time when many may not be fully prepared for winter-like conditions. The NWS notes that sensitive vegetation, uncovered crops, and outdoor water sources could be affected if temperatures fall more quickly than expected.
Threats to Crops, Livestock, and Outdoor Residents
Local agriculture experts warn that temperatures near freezing can stress certain produce varieties, particularly early winter vegetables and orchard crops. Livestock owners are also urged to take precautions as animals exposed to extended cold may experience health issues.
Officials stress that “residents should dress in layers, use heaters safely, and avoid using grills or generators indoors due to the risk of carbon monoxide poisoning.” Additionally, vulnerable populations—including the unhoused and elderly residents—may face increased health risks if adequate shelter or heating is unavailable.
Safety Measures Recommended for Tonight
Authorities and forecasters recommend taking several steps before temperatures drop:
- Cover outdoor plants or bring potted vegetation inside
- Provide warm shelter and fresh water for pets and livestock
- Ensure space heaters are used on stable surfaces and never near flammable objects
- Avoid bringing charcoal grills, fuel-powered heaters, or generators indoors
- Check on neighbors who may lack adequate heating
Local emergency officials also encourage residents to monitor updated forecasts, as conditions may shift depending on cloud cover and wind direction through the night.
Temperatures Will Rebound By Morning
The cold spell is expected to be short in duration. As clear morning skies allow sunlight to warm the surface, temperatures should rise steadily after sunrise. By late morning Thursday, inland valleys are forecast to return to more typical early-December levels.
Conclusion
San Benito and Monterey Counties are preparing for a brief but potentially impactful cold event as temperatures approach freezing overnight. With risks to agriculture, pets, livestock, and those without reliable shelter, residents are encouraged to take precautions and stay alert to updated advisories.
