As the remnants of Hurricane Priscilla edge closer to Southern California, San Diegans should prepare for a shift in weather conditions this week. According to the National Weather Service San Diego, weak offshore flow today will give way to chances of showers and thunderstorms from Thursday into Friday night due to tropical moisture entering the region. The mountain areas could particularly feel the brunt of this change with gusty easterly winds reaching up to 25 mph this morning. NWS San Diego predicts high temperatures for inland areas will drop significantly below average by Monday.

The approaching moisture, a byproduct of what was once Hurricane Priscilla, poses uncertainty for the exact timing and intensity of the expected rainfall. Weather models indicate the potential for downpours and storms as early as Thursday, calling for a tentative eye on the sky for San Diego County mountains since chances for measurable rainfall are pegged between 55 and 65 percent. Despite this, the county may see a brief respite with gradual drying anticipated over the weekend. By early next week, the cooling period is expected to usher in high temperatures for inland areas ranging from around 70 near the coast to mid-80s for the lower deserts, as per the National Weather Service.

Marine conditions, however, will likely remain less affected. The only expected marine advisories are a slight chance of thunderstorms between Thursday and Friday and potentially gusty winds near San Clemente Island on Friday afternoon and evening. This forecast comes amidst a relatively calm week for coastal goers, with no hazardous marine conditions projected through at least Saturday. "Otherwise, no hazardous marine conditions are expected through Saturday," as the NWS San Diego noted.
