A line of storm cells moved over the Los Angeles Basin on late afternoon and early evening Monday, dumping rain during rush hour and prompting a flood advisory.
Moderate-to-heavy rain fell in isolated showers along the coast and the South Bay, the San Fernando and San Gabriel valleys and downtown Los Angeles, the National Weather Service said.
Earlier, an urban and small stream flood advisory was issued for southern Los Angeles County through 7:30 p.m. Minor flooding was expected in downtown L.A., Pasadena, Griffith Park, Long Beach and several other areas.
Locally heavy showers occurred in a line extending from north of Torrance up to Glendale, the weather service stated on Twitter.
By 4:40 p.m., close to an inch of rain had fallen in areas northeast of downtown L.A.
The intersection of South Bernal Avenue and East Sixth Street in Boyle Heights appeared to be flooded, aerial video from Sky5 showed about 5:15 p.m.
The Los Angeles Fire Department confirmed it was responding to flooding nearby, saying it was reportedly due to clogged drains.
Ponding water could affect commuting drivers, the weather service warned.
