The hottest day is expected to be Sunday, with inland temperatures about 12 to 18 degrees above normal.
Highs on Sunday could reach the mid-90s in the inland valleys and low 100s in the lower deserts. However, the marine influence should help coastal
areas stay in the mid-70s, according to the Weather Service.
San Diegans are encouraged to avoid strenuous outdoor activity, during the hottest part of the day, wear light clothing, and drink plenty of non-alcoholic fluids. Drivers are also warned not leave pets in enclosed vehicles - even if it's only for a short time.
