The heat wave will continue in the San Diego County mountains and deserts on Saturday, but cooler conditions will prevail along the coast, according to the National Weather Service.

“Hot and dry conditions will continue from the foothills, across the mountains and into the deserts this weekend, while the coastal basin is moderated by the marine layer and sea breezes,” forecasters said.

Highs Saturday are expected to be 71 to 76 near the coast, 78 to 83 inland, 81 to 86 in the western valleys, 90 to 95 near the foothills, 92 to 102 in the mountains and 116 to 121 in the deserts.

The heat in Borrego Springs reached a record 116 on Friday, but no other records were set in San Diego County that day.

An excessive-heat warning remains in effect through 9 p.m. Saturday in the western valleys, 9 p.m. Sunday in the mountains and 9 p.m. Sunday in the deserts.
