SAN DIEGO – An excessive heat warning for the mountains and deserts will go into effect Sunday and last through Wednesday, weather experts said.

According to the National Weather Service in San Diego, strong area of high pressure will create very hot weather inland this weekend through at least early next week.

High temperatures up to 20 degrees above normal are expected by Sunday with areas of the Coachella Valley and lower desert approaching the 120 degree mark by Monday.

High temperatures will gradually lower by the middle of next week west of the mountains with the lower mountain slopes and deserts likely to remain hot.

High temperatures of 108 to 113 degrees are expected in the high desert, 110 to 120 degrees in the Coachella Valley and San Diego County deserts, 100 to 105 along the lower mountain slopes and 90 to 96 at resort levels in the mountains.

County residents can seek relief at "cool zones" located throughout the county, places such as the El Cajon Library or Parkway Plaza.
