As summer grips the region, San Diego expects scattered thunderstorms and heavy rains in the mountains and deserts. According to the National Weather Service San Diego, monsoonal moisture would lead to these thunderstorms on Monday, with a continuation of more isolated showers and thunderstorms over the mountains on Tuesday. Forecasters predict that temperatures will hover near or slightly above seasonal norms early this week, with hotter weather likely returning in the second half of the week. Coastal areas will see low clouds at night and in the morning through most of this week.
Commuters in coastal areas wake up to blankets of low clouds spreading inland, expected to retreat to the coast later this morning. The National Weather Service detailed the possibility of a few sprinkles resulting from a thin plume of elevated instability, although no significant rainfall or lightning has been observed. Meanwhile, another about of thunderstorms is anticipated across the mountains starting this afternoon, potentially leading to localized minor flooding in those regions.
Aviation interests should be wary, as scattered thunderstorms might cause erratic winds and strong up/downdrafts where they develop. The National Weather Service's aviation section forecasts thunderstorms from 19Z Monday to 02Z Tuesday in the mountains, and, although less likely, the deserts might also see some action between 20Z Monday and 00Z Tuesday. These conditions could affect KPSP and KTRM with strong outflow gusts and lightning from nearby storms.
On the water, beachgoers and mariners can sigh relief as no hazardous marine conditions are expected through Friday. Yet, beach hazards are afoot with a Beach Hazards Statement in effect from Tuesday morning through Thursday evening for Orange County Coastal Areas and San Diego County Coastal Areas, as National Weather Service reports specified. A long SSW swell period will significantly elevate surf conditions, leading to potential sets reaching 7 feet and a high risk of dangerous rip currents. Although the surf is predicted to decrease gradually over the weekend, caution among beach visitors and water enthusiasts remains highly advised.
