Rain was moving through San Diego Sunday morning, with gusty west winds adding a rough edge to the unsettled start. Showers, coastal flooding and dangerous surf are expected to keep conditions unsettled through the afternoon.

The city is forecast to reach about 70 degrees, with rain showers continuing and southwest winds of 10 to 15 mph, including gusts up to 30 mph. In the most likely scenario, rainfall totals could reach 0.75 to 1.5 inches west of the mountains in San Diego County. Rain is expected through the morning, with showers becoming increasingly scattered in the lowlands during the afternoon.

Flood And Coastal Alerts Remain In Effect

A Flood Watch remains in effect across San Diego County through Sunday evening as runoff could swell creeks, rivers and other flood-prone areas, according to the National Weather Service. Drivers should avoid flooded roads and never cross water of unknown depth.

Along the coast, a Coastal Flood Warning remains in effect until 3 p.m., with minor coastal flooding possible into Tuesday. Surf is expected to run 5 to 7 feet, with sets up to 9 feet, creating strong rip currents, beach erosion and potentially dangerous conditions near low-lying roads and boardwalks.

Rain Lingers Into Monday Before Skies Clear

Isolated showers are possible, and winds may ease later. Monday should remain mostly cloudy with more rain showers, a high in the 60s and a 60% chance of precipitation.

Showers may linger into Monday night before the pattern dries out Tuesday. Tuesday is expected to be mostly sunny with a high near 70, followed by sunny skies and a high near 73 on Wednesday.

Late-Week Heat Builds Quickly

The forecast calls for a warming trend, with highs in the 80s Thursday and possibly the 90s near the coast Friday and Saturday. Drier conditions are expected from Tuesday onward, making the weekend forecast look very different from Sunday's stormy setup.
