San Diego's weather forecast: Goodbye sun, hello rain

FORECAST | RADAR


Meteorologists are expecting San Diego County to see heavy rainfall this week—warning residents of possible flash floods in some areas.

A weak trough of low pressure will bring gusty winds and a small chance of light precipitation over and west of the mountains late today into early Thursday, according to the National Weather Service. By early Friday, a second and much stronger storm is expected to bear down on the entire region.

"A large strong low pressure system over the Eastern Pacific will move slowly inland through California for Friday through the weekend, bringing periods of heavy precipitation and strong gusty winds," according to the weather service, which forecast widespread rain and winds Friday morning into Friday afternoon, and intermittent showers and winds from Friday night to Sunday.

Rainfall totals from the second storm are expected to range from 1 to 2 inches along the coast to 3 to 5 inches on coastal mountain slopes, though local amounts could exceed 7 inches on south-facing mountain slopes.

Sandbags

In anticipation of the heavy rain, the San Diego Fire-Rescue Department will give out sandbags to those who live in areas that are prone to flooding (follow the link for a list of locations). The limit is 10 bags per household.

Folks who live in La Mesa can stop by the Public Works Operations Center at 8152 Commercial Street to pick up free sandbags. They will be available on a first-come, first-served basis. The limit is 10 bags per household.

Work Postponed

Caltrans had planned some closures along I-805 to do some work for new carpool lanes that will open up for traffic next month, but decided on Tuesday that the forecast was a little too rainy to do what they had planned.

On Wednesday, the North County Transit District, which had been planning some rail work, announced that they, too, would be postponing their plans. The work would have suspended Amtrak and Metrolink service in San Diego County this weekend. Instead, all rail service will operate on normal schedules.

Historical Numbers

Despite the estimated rainfall—San Diego has seen wetter days in its history.

The National Weather Service released data about the wettest 48 hours in San Diego history. The data shows the region would need almost three inches of rain just to make it to the "Top 25."
