An upper level ridge of high pressure and weak offshore flow will bring very hot and dry weather from Sunday through Wednesday, elevating the risk of wildfire in the region, forecasters said.
Monday and Tuesday will be the hottest and driest days, according to the National Weather Service, which forecast highs in the 90s even at some beaches, and triple digits in the valleys and deserts.
“A cooling trend will take place Thursday and Friday of next week as the upper ridge weakens and onshore flow returns,” according to a weather service advisory.
While San Diego temperatures are expected to hit the 90s and East County to top out in the triple digits, Coronado will not be immune.
Highs in town are expected to reach the high 70s starting Sunday, and rise to 87 by Tuesday.
