SAN DIEGO -- Lingering showers are expected in parts of San Diego County today but should taper off later in the day as a cool storm that led to power outages, roadway flooding and record rainfall moves out of the region.
In a 48-hour period ending at 10 p.m. Tuesday, automated gauges in the mountains collected 1.39 inches of rain in Pine Hills, 1.21 inches at Lake Cuyamaca, 1.01 inches in Julian and .91 of an inch in Descanso, according to the National Weather Service. One location, Alpine, tallied a record one-fifth of an inch, exceeding the prior Nov. 3 milestone of 0.11 of an inch, the NWS reported.
In the valleys, gauges collected 1.11 inches in San Miguel, 1.07 inches in Lemon Grove, .74 of an inch in La Mesa and .58 of an inch in Ramona. In the coastal areas, 1.30 inches was recorded at Montgomery Field, 1.01 inches in University Heights, .89 of an inch at Fashion Valley and .87 of an inch at Lindbergh Field.
The storm also flooded part of westbound Interstate 8 in Mission Valley, and Federal Boulevard at San Miguel Avenue in Lemon Grove, according to the California Highway Patrol.
Power outages overnight were also blamed on the severe weather, according to San Diego Gas & Electric. Utility crews were working to restore electricity to homes in businesses in Clairemont, Kearny Mesa, Linda Vista and Mission Valley.
A few scattered showers are expected along the coast this morning and in the valleys and mountain this afternoon, forecasters said.
Forecasters said the showers had all but ended 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.
