A warming trend is heading to San Diego County Tuesday and will set in for the rest of the week and into next weekend, forecasters said.
An excessive heat warning will be in effect until at least 8 p.m. Friday, with dangerously hot conditions and highs between 110 and 118 degrees in the desert, according to the National Weather Service.
A heat advisory is in effect for the San Diego County valleys from 11 a.m. Friday until 11 p.m. Saturday, with temperatures between 90 and 100 expected.
Officials advised people in those areas to drink plenty of fluids, stay in an air-conditioned room, stay out of the sun and check up on relatives and neighbors.
Authorities also reminded the public to never leave pets or children inside vehicles on days that are even a little warmer than normal, as locked cars can turn into death traps in mere minutes.
