The National Weather Service office in San Diego issued a heat advisory for the county’s inland valleys as temperatures were forecast to reach the mid 90s to near 100.

The advisory for much of the center of the county is in effect from 10 a.m. Tuesday to 8 p.m. on Wednesday.

The weather service said weak Santa Ana winds will contribute to fire weather conditions on Tuesday.

“Lowest daytime humidity for the mountains, deserts, and inland valleys will fall to around 10% today,” the weather service warned, with wind gusts of up to 30 mph in the afternoon.

Highs on Tuesday were forecast to be 74 to 79 near the coast, 83 to 88 inland, 87 to 92 in the western valleys, 93 to 98 near the foothills, 85 to 92 in the mountains and 99 to 104 in the deserts.
