Rumblings are expected Thursday in the mountain and deserts areas of San Diego County as summer thunderstorms threaten the region, but the storm clouds also brought a cooling to desert areas.
“Increasing moisture and instability will generate thunderstorms over the mountains and deserts during the day today,” according to the National Weather Service. “Deep layer moisture will be sufficient for locally heavy rain, leading to the potential for excessive runoff in normally dry creeks and streams.”
A flash flood watch for local mountain and desert areas was scheduled from 11 a.m. through Thursday evening.
“Excessive cloud cover and rainfall today and tonight will lower the threat of excessive heat occurring over the desert regions,” an agency advisory read.
In the same advisory, the weather service issued a wind warning for valley and mountains areas until 2 p.m. During the wind warning period, those areas will be subject to east wind gusting 35 to 50 miles per hour, according to the weather service.
“Wind this strong can make driving difficult, especially for high-profile vehicles,” the agency advised. “Use extra caution.”
