SAN DIEGO -- High temperatures are expected to peak Monday as the heat wave in San Diego County persists, and the hot weather combined with low humidity and breezy winds will increase the risk of wildfires in some areas.
A National Weather Service heat advisory for areas other than the immediate coast is set to expire at 6 p.m. Meanwhile, a Red Flag warning for the mountains and deserts was issued Monday afternoon and will remain in effect from through Wednesday evening.
High temperatures today are predicted to be 80 to 85 degrees along the coast, 84 to 89 degrees inland, 92 to 97 degrees in the western valleys, 97 to 102 degrees near the foothills, 93 to 99 degrees in the mountains and 109 to 114 degrees in the deserts, according to the National Weather Service.
"A strong high pressure ridge will result in more hot weather for inland locations. A sea breeze will keep coastal areas cooler," according to the weather service. "Gradual cooling is expected for the remainder of the week, although temperatures will still be above normal in some areas through Wednesday."
Forecasters said hot weather combined with low humidity and gusty winds would likely cause any fires that develop to spread rapidly. Outdoor burning was discouraged.
Residents were advised to guard against potentially serious heat-related ailments, stay hydrated, avoid unnecessary outdoor labor and check on neighbors and relatives, especially the elderly. Authorities also warned against leaving people or pets in parked cars, which can quickly become death traps in high heat.
