Effective Wednesday, November 20, 2019, Sonoma County is issuing a cold weather advisory in response to the National Weather Service’s prediction for temperatures in the 30's overnight in parts of the county that might also be without power. Strong winds may increase the danger from cold temperatures (wind chill). Infants, the elderly, those without shelter or heat, and people using alcohol or other drugs are at higher risk from health problems caused by cold.
