LOS ANGELES (CBSLA.com) — A lingering high-pressure system is expected to bring above-average temperatures to the Southland through Tuesday.
The National Weather Service (NWS) says the heat is expected to build this weekend.
Meteorologist Kaj Goldberg, reporting for CBS2 and KCAL9, says triple-digit temperatures are possible through Tuesday.
A fire weather watch for the mountains of Los Angeles and Ventura counties is expected to go into effect at 6 a.m. Monday through 6 p.m. Tuesday, according to the NWS.
Those planning on going outside are urged to drink plenty of water and avoid strenuous outdoor activity.
The NWS also urged drivers to not leave pets, children or the elderly unattended in a vehicle even with the windows down as temperatures can climb to life-threatening levels within minutes.
