The flash flood watch from the National Weather Service is scheduled to take effect at 11 a.m. and extend until Tuesday afternoon. Although the San Diego coast was not included in the watch, FOX 5 weathercaster Chrissy Russo said showers, thunderstorms and humidity are likely there as well. Temperatures along the coast will likely push into the low 80s, with inland temperatures hitting the high 80s, Russo said.
Different forecast models are predicting very different outcomes, Russo said. Once scenario shows no rain falling on San Diego County Monday, but another predicts up to 0.75 inches falling along the coast and up to 1.5 inches in the mountains, she said. The heaviest rain is likely to fall Monday afternoon, she said.
Forecasters with the NWS predicted rainfall in excess of an inch in the deserts and the inland valleys, and more than two inches in the mountains. The heaviest rain was likely to fall between Monday evening and Tuesday morning, according to the NWS.
Forecasters said drier conditions would prevail later this week as high pressure builds over the southwest.
