Record breaking rainfall soaks San Diego County

The now post-tropical storm impacted the county with most of the rain seen in local mountains and deserts. Chances of rain will continue throughout the weekend.

SAN DIEGO COUNTY, Calif. — Tropical Storm Kay has abruptly shifted San Diego's weather out of an oppressive heat wave and into a period of rain, high winds and fears of flooding.

More than a half-inch of rain had already fallen at the airport as of Friday, while more than three-quarters of an inch had fallen in other areas.

A flood watch will be in place through Saturday evening in San Diego County mountains, deserts and valleys.

"Warm, windy and humid conditions will continue through this evening with occasional heavy rain bands and embedded thunderstorms moving across Southern California due to Tropical Storm Kay located about a hundred miles southwest of San Diego," according to the NWS. "Areas of heavy rain could cause flooding problems through Saturday, as deep tropical moisture lingers across our area. Scattered thunderstorms will be possible again each day Sunday through Tuesday, as well, as Kay slowly dissipates, but stalls out, southwest of San Diego, through Tuesday. Although it will remain more humid than normal through next week, temperatures will be much more seasonal."

Forecasters said mountain and desert areas could get 2 to 4 inches of rain, with some mountain slopes getting as much as 8 inches. Valley areas could get as much as 1 to 3 inches.

Kay had been categorized as a hurricane, but it weakened as it made landfall Thursday night, then began shifting to the northwest over the ocean. But Kay was still packing a punch, promising to bring widespread rain across the region.

Record rainfall and gusty winds impacted roads across San Diego County on Friday.  

Wind gusts created a hazard for drivers. In other parts of the county, high winds knocked over trees and downed powerlines.

The heavy rain in the South Bay and Tijuana is creating concerns about beaches in the area. Beachgoers are warned to stay out of the water in Imperial Beach due to alarmingly high bacteria levels.

The wet weather created a tough commute for drivers as rain from Tropical Storm Kay soaked the roads.

Showers impacted most of San Diego County with most of the rainfall seen in local mountains and deserts. Chances of rain will continue throughout the weekend.

As they have in the past, the County and Cal Fire  provided free bags and/or sand at numerous fire stations for people who live in the unincorporated areas.

Rain can cause flooding and erosion, particularly in areas that are not covered by plants, landscaping, grass and trees. Rain runoff can sweep topsoil, mud, plant material and debris off land and downstream where it can damage homes, clog culverts and storm drains, and flood and damage roadways.

Sand and bags, or bags alone, will be available for unincorporated residents at the fire stations located below.
