September 1, 2020 – Triple digit heat is possible this Labor Day weekend into early next week for the Central Valley, foothills, and Delta due to strong high pressure over Northern California. There is the potential for moderate to very high heat risk during this time, which could impact the general population, especially those spending an extended time outdoors. Any localized dense smoke may impact these temperatures.


WHAT: Dangerously hot conditions with afternoon highs 100 to 110 for the Valley, and 95 to 105 for the foothills. Overnight lows in the mid to upper 60s to around 80.

WHERE: Central Valley, Delta, foothills, and mountains southwestern of Shasta County to western Colusa County.

WHEN: From Saturday morning through Tuesday afternoon.

IMPACTS: Heat related illnesses such as heat exhaustion and heat stroke can occur due to prolonged exposure to hot temperatures, even to the general population. People most vulnerable include those who spend lots of time outdoors, those without air conditioning, young children, the elderly and those with chronic illness.

Monitor the latest forecasts and warnings for updates on this situation. Be prepared to drink plenty of fluids, stay in an air- conditioned room, stay out of the sun, and check up on relatives and neighbors.

Young children and pets should never be left unattended in vehicles under any circumstances. This is especially true during warm or hot weather when car interiors can reach lethal temperatures in a matter of minutes.
