Record temperatures felt in parts of San Diego County

The National Weather Service issued an excessive heat warning that will be in effect from 10 a.m. Saturday through 8 p.m. Monday in the deserts.

SAN DIEGO — There has been a lot of hot air over San Diego County this weekend, with record or near-record heat felt in some areas.

Ramona reached 101 degrees at 1 p.m Saturday, which eclipsed the previous record of 100 set in 1983, according to the National Weather Service.

It was 99 degrees in El Cajon and 98 in Escondido at 1 p.m.

The sea breeze moderated temperatures near the coast, where the San Diego Airport temperature reading was 79 degrees.

The mercury will continue to rise in the county's western valleys, mountains and deserts as a result of a heat wave that will keep those areas scorching until Monday, the NWS said.

A strong system of high pressure has been building over Arizona and New Mexico, ushering in sweltering heat in most of Southern California through Monday, forecasters said.

The NWS has issued an excessive heat warning that will be in effect through 8 p.m. Monday in the deserts, while a heat advisory will last through 8 p.m. tonight in the western valleys and the mountains.

NWS officials urged residents to drink plenty of fluids, stay out of the sun and check up on relatives and neighbors. Also, young children, senior and pets should never be left unattended in a vehicle parked during the day, with car interiors able to reach lethal temperatures in minutes.

Sunday's high could reach 120 in some desert communities.

A slight cooling trend will arrive in the deserts Tuesday and continue through Thursday, forecasters said.
