Lingering showers continued in parts of San Diego County Wednesday morning, but the rain should taper off later Wednesday as a cool storm that led to power outages, roadway flooding and record rainfall moves out of the region.

On Tuesday, the 1.09 inches of rain at Lindbergh Field topped the previous record for the day of .70 of an inch, set in 1850. The precipitation also pushed the locale well over its average rainfall amount of 1.01 inches for all of November. Also on Tuesday, Alpine tallied a record one-fifth of an inch, exceeding the prior Nov. 3 milestone of 0.11 of an inch, according to the National Weather Service.

In a 48-hour period ending at 4 a.m., automated gauges in the mountains collected 1.03 inches in Julian and .94 of an inch in Descanso, .60 of an inch on Palomar Mountain, and .53 of an inch on Mount Laguna, according to preliminary precipitation totals from the NWS.

In the valleys, gauges collected 1.23 inches in Lemon Grove, .85 of an inch in La Mesa, .65 of an inch in Alpine and Potrero, .59 of an inch in Ramona and .55 of an inch in El Cajon. In the coastal areas, 1.41 inches was recorded at Montgomery Field, 1.14 inches in National City, 1.10 inches at Lindbergh Field and .65 of an inch in Chula Vista.

The storm also flooded part of westbound Interstate 8 in Mission Valley, and Federal Boulevard at San Miguel Avenue in Lemon Grove and Quarry Dip Road in Spring Valley, authorities said.

Power outages overnight were also attributed to the severe weather, according to San Diego Gas & Electric. Utility crews were working to restore electricity to homes in businesses in Clairemont, Linda Vista and Mission Valley.

A few scattered showers are expected stick around this morning along the coast, and into this afternoon in the valleys and mountains, forecasters said.

Forecasters said the showers had all but ended for the time being in southwestern San Diego County, but the transition to fairer and drier weather would not be so clean.

“While our big trough of low pressure slowly moves east, a final shortwave will rotate down from Nevada and graze our area today with just enough energy to wring out a few more showers,” according to the weather service.

But another warming trend will begin Thursday and continue into the weekend, according to the NWS.
