SAN DIEGO, CA — More record high temperatures were reported Thursday in parts of San Diego County.

It was 105 degrees Thursday in Campo, breaking the record of 103 degrees set in 1980, according to the National Weather Service. It was the third consecutive day a record high was reported in Campo, where it was 105 degrees on Tuesday and 102 degrees on Wednesday.

It was also the third day in a row a record high was reported in Palomar Mountain. It was 90 degrees Thursday in Palomar Mountain, breaking the record of 86 degrees set in 1964. It was 93 degrees Tuesday and 92 degrees Wednesday in Palomar Mountain.

An excessive heat warning was extended until 8 p.m. Monday for the county's deserts and inland valleys, according to the NWS.

Dangerously hot conditions are expected with high temperatures from 106 to 112 degrees in the deserts, forecasters said. High temperatures are expected in the mid 90s to 103 degrees in the inland valleys.

"Hot conditions are expected for inland areas through Monday. Influence from the marine layer will help moderate temperatures closer to the coast," NWS San Diego forecasters wrote Friday. "The marine layer will become shallower over the weekend, becoming more confined to coastal areas. A gradual cooling trend is expected for much of next week, with temperatures returning to near or slightly above average by Thursday."

Extreme heat will significantly increase the potential for heat-related illness, according to the NWS. People should drink plenty of fluids, stay in air-conditioned rooms, stay out of the sun, and check on relatives and neighbors. Young children and pets should never be left unattended in vehicles under any circumstances.
