The National Weather Service has issued a Heat Advisory for the Mother Lode and the Sierra Nevada through 8 PM Thursday.
An Excessive Heat Warning has been issued for the Norther San Joaquin Valley through 8 PM Thursday.
High temperatures in the Central Valley will range from 105 to 110 degrees today. The highs will range between 102 to 110 degrees on Tuesday, Wednesday and Thursday.
Overnight low temperatures in the Central Valley will be mostly in the upper sixties to upper seventies Tuesday, Wednesday and Thursday morning.
High temperatures in the Mother Lode will be well into the 90’s to 105 degrees through Thursday.
Thermal belt areas in the Mother Lode will only be cooling into the mid 70s to lower 80s for nighttime lows.
This extended heat event will increase heat related illnesses for those who are exposed to prolonged heat, especially the elderly, children and other sensitive groups without air conditioning.
There will be heat stress to livestock with limited relief from the heat during the overnight hours.
The Sierra Nevada waterways are running very cold and fast, increasing the risk for hypothermia and the probability for water rescues.
The heat will gradually subside over the weekend, but triple digit heat expected through Saturday.
A Heat Advisory means that a period of hot temperatures is expected. Very hot temperatures can create a situation in which heat illnesses are possible. Drink plenty of fluids, stay in an air-conditioned room, stay out of the sun, and check up on relatives and neighbors. Take extra precautions if you work or spend time outside. When possible, reschedule strenuous activities to the early morning or evening. Know the signs and symptoms of heat exhaustion and heat stroke. Wear light weight and loose fitting clothing when possible and drink plenty of water. 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.
