Up To 89 Degree Temperatures In San Juan Capistrano: Heat Watch

SAN JUAN CAPISTRANO, CA — A heat advisory warning of potential heat-related illnesses was in effect Tuesday throughout Orange County, including San Juan Capistrano. The heat advisory was issued by the National Weather Service and will be in effect from Wednesday morning to Thursday afternoon.

San Juan Capistrano residents can expect unusually high temperatures up to 89 degrees Fahrenheit, the National Weather Service reported. The heat advisory impacts Orange County, San Bernardino and Riverside County valleys and the Inland Empire.

The heat surge is not common for February, weather experts said, and the unseasonable heat will increase the potential for heat-related illnesses for visitors from other parts of the country where it is normally cold.

"Young children and pets should never be left unattended in vehicles under any circumstances," The National Weather Service said in a statement. "This is especially true during warm or hot weather when car interiors can reach lethal temperatures in a matter of minutes."
