Temperatures will continue to soar well into the triple digits in the deserts this week and into next weekend, with more moderate temperatures in the coastal and valley areas, the National Weather Service said Sunday.

Sunday’s high in Borrego Springs was 107 degrees, and temperatures were expected to climb steadily throughout the week, reaching 110 on Wednesday and 117 by next Sunday.

The NWS issued an excessive heat warning from 10 a.m. Tuesday to 8 p.m. Sunday for the county’s desert and mountain areas.

Officials from Cleveland National Forest announced that San Diego River Gorge, Cedar Creek Falls, Three Sisters Falls and Eagle Peak trails will be closed starting Monday due to excessive heat.

The NWS advises people to drink plenty of fluids, stay out of the midday sun, and check up on relatives and neighbors during extreme heart events.

“Young children and pets should never be left unattended in vehicles under any circumstances,” the agency cautioned.

Highs will climb into the 90s in the mountain and valley areas this week, but will remain comfortable nearer the coast.

Monday will bring patchy fog before 11 a.m., then sunny skies and a high near 73, forecasters said. Highs in the downtown area will creep up to 78 on Wednesday and Thursday and stay in the mid-70s through the weekend.
