The weather forecast for San Diego has been a mix of showers and periodic thunderstorms. According to their latest synopsis, a low-pressure system off the West Coast is actively drawing moisture from Tropical Storm Priscilla, affecting the region through Saturday morning. Conditions are anticipated to cool with an expected return of the marine layer early next week, as reported by the National Weather Service in San Diego.
Today, across the southwestern California region, including San Diego, Orange, Western Riverside, and Southwestern San Bernardino counties, residents experienced light showers. As this band of rain continues to drift northward slowly, the National Weather Service has suggested that precipitation has been relatively light, only "ranging from a trace to about two tenths inch in the last 12 hours." Nevertheless, wet weather will persist, with the chances for thunderstorms and heavier rainfall increasing by late today, especially over the mountains and deserts. Residents should be cautious as localized heavy rainfall cannot be entirely ruled out.
Regarding weekend forecasts, fair and cooler weather is expected to take hold late Saturday through Monday. With the strengthening onshore flow late Saturday into Sunday, gusts could reach up to 50 mph in mountain passes and adjacent desert areas. Early indications for the upcoming work week suggest a chance of showers for Tuesday and Wednesday, with potential for strong westerly winds, as a second low-pressure system moves southward along the West Coast. While unsettled weather may persist, the timing and intensity remain uncertain due to diverging model solutions.
For marine conditions, no hazardous situations are expected to arise today through Tuesday, as per NWS San Diego's marine forecast. However, northwest wind gusts could occasionally exceed 20 knots around San Clemente Island during the afternoons and evenings of both today and Saturday. Therefore, Coastal dwellers and mariners should remain vigilant during these periods.
The National Weather Service is not activating Skywarn, but encourages weather spotters to report significant conditions. Rainfall totals through Saturday are expected to be lighter in the coastal regions. At the same time, the mountains and deserts may see higher totals due to the possibility of heavier showers and thunderstorms. Localized urban flooding is also a concern in the desert areas, where rain rates could be higher.
