The National Weather Service has issued an excessive heat watch for the area through Friday.
Dangerous heat is predicted, with afternoon highs between 99 and 108 for the Valley, 95 to 102 for the Foothills and mostly 90s for the Delta. Overnight lows will drop down only into the 60s to 70s.
The warning is in effect for the Sacramento Valley and surrounding foothills, the northern San Joaquin Valley and portions of the Delta.
Heat related illnesses such as heat exhaustion and heat stroke can occur due to prolonged exposure to hot temperatures, including those in the general population. People most vulnerable include those who are spending lots of time outdoors, those without air conditioning, young children, the elderly and those with chronic ailments.
For those that hope to get some relief from the heat in the water, officials have also issued a reminder that local rivers and streams are running fast and cold. Cold water safety should be practiced when on and near the water.
Residents are advised to monitor the latest forecasts and warnings for updates on the 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.
