SAN DIEGO, Calif. – A calm, foggy start across the coast hides what’s coming. The Pacific is brewing a powerful late-fall system that’s set to end San Diego’s recent dry streak with a surge of heavy rain, thunderstorms, and gusty winds by Thursday night.
Clouds will thicken throughout Thursday before the first showers reach the coast by evening. The National Weather Service expects rainfall to intensify after sunset, with embedded thunderstorms possible across coastal and inland valleys. Some of these storms could deliver brief downpours and lightning, especially between 10 p.m. Thursday and mid-afternoon Friday. Rainfall totals could reach 1 to 2 inches in coastal areas, with higher amounts possible in the foothills.
Friday will stay wet, with steady rain and gusty winds reducing visibility on I-5, I-15, and Route 163, likely slowing the morning commute. By Friday night, storms may briefly turn strong, capable of producing localized flooding in low-lying or poor-drainage areas. The National Weather Service warns drivers to avoid flooded roads and secure outdoor items that could blow around in gusty conditions.
The system lingers into Saturday, bringing scattered showers and possible thunder before tapering later in the day. Sunshine and mild temperatures are expected to return Sunday, giving San Diegans a break for outdoor plans or early Thanksgiving travel preparations.
While this isn’t a “winter storm” by definition, it’s an early November reminder that the region’s rainy season has arrived. Forecasters say additional Pacific waves could follow next week, signaling a shift toward a more active, wetter pattern just as the holiday season approaches.
