SAN DIEGO – Thunderstorms could bring dry lightning to the San Diego area Monday, according to the National Weather Service.
Forecasters said mid-level atmospheric moisture flowing up from Mexico could meet a small low pressure system blowing in from the northwest. The resulting atmospheric instability could trigger thunderstorms in coastal San Diego and the mountains of East County.
“The lower layers of the atmosphere will remain very dry Monday and will contribute to a threat of dry lightning,” the NWS said in a statement. “Due to the strength of the low pressure system, there could be frequent lightning from the mountains westward to the coast.”
Windy conditions were also expected in the mountains of San Diego County, including the Palomar Mountain and Descanso ranger districts in the Cleveland National Forest. Most wind speeds were forecast to be about 20 mph or less, with gusts up to 35 mph.
