Storm Heading for San Diego Bringing Rain, Wind and Snow – NBC 7 San Diego
A much-needed winter storm will move from northern California to San Diego County overnight, bringing rain, high winds, mountain snow, and possibly even thunderstorms to the area.
While the county will face an occasional speckle on Monday as the system moves in, much of the storm’s activity is forecast to occur from Tuesday afternoon through evening. NBC-7 meteorologist Sheena Parveen said the public should be prepared for constant showers.
“We expect heavy rain and some of that rain can generate rainfall rates of about three quarters of an inch an hour,” Parveen said in her forecast. “That is heavy rain.”

Due to the expected rainfall, the National Weather Service has issued a flood watch that will be in effect from Tuesday morning through evening. The agency warns that “excessive runoff can lead to flooding of rivers, streams, creeks and other low-lying and flood-prone locations.”
In addition to the wet weather, the winds will gradually increase from Monday night to Tuesday. For this reason, a wind warning applies from Tuesday 1 p.m. to Wednesday 1 a.m.
Coastal winds can reach speeds of up to 45 miles per hour, while isolated mountain and desert gusts can be harmful, reaching over 60 miles per hour.
Rain, snow and wind. Oh my! 🌧️❄️
The forecast remains on course for the storm at the end of Mon to the beginning of Wed. Tue will be the day with the heaviest rain and snow.

Maneuvering a vehicle in bad weather can be difficult, and it can be annoying when you start out on the seaplane. NBC 7’s Ashley Matthews explains what to look for in this case.
“I wouldn’t be surprised if we had storm-related blackouts at all tomorrow because we can see gusts of wind close to 120 km / h,” said Parveen. She added that the upcoming system has the potential to bring thunderstorms to the area.
The highest mountains in San Diego County could also get some snow from the storm. For the forecast on Tuesday, up to 10 cm of snow is forecast.
Due to the bad weather, Cal Fire is offering free sandbags to residents of the county to help ward off rain runoff. Click here for more information on how to claim the freebie.
