LOS ANGELES (CBSLA.com) — A storm system slowly moving out of the Southland on Monday dumped heavy rain in the San Gabriel Valley, flooding some streets in Temple City. 

Rain began falling by mid-afternoon in areas of Pasadena, Arcadia and San Gabriel. Some streets were flooded in Temple City thanks to a sudden heavy downpour.

Standing water could be seen from Sky9 just outside of numerous Temple City residences on Roseglen Street as a heavy stream of storm water drained into a wash.

Residents later told KCAL9’s Rachel Kim that the water receded after a resident removed a trash can that was blocking a drain.

“We had a cloudburst,” local resident David Ponder said. “Normally when we get a cloudburst we’ll get water curb to curb. But because the drain was plugged partially with a trash barrel, the water came up.”

Thunderstorm activity was also reported in the far western reaches of the county.

There were also heavy downpours in parts of Riverside County on Monday. By mid-afternoon, Corona, Eastvale, Norco, Moreno Valley and Riverside were all under overcast conditions, with a line of rain cells tracking northeast. There were no reports of significant flooding.

Showers were expected to taper off Monday night, with a return of sunshine Tuesday and the onset of a slight warming trend for the balance of the week, forecasters said.

The weather will be changing throughout the Southland, with sunny skies and higher temperatures expected for the next six days, according to an NWS forecast.

For example, the high in downtown L.A — 75 degrees Fahrenheit today — is expected to rise to 79 Tuesday, 84 Wednesday, 86 Thursday, 92 Friday, and 97 on Saturday and Sunday. The San Fernando Valley is forecast to have a high of 76 today, 81 Tuesday, 89 Wednesday, 91 Thursday, 99 Friday and 103 on Saturday and Sunday.

Today’s precipitation was the result of a low-pressure system expected to be replaced midweek by high pressure — not from around Texas, as usual, but from the west, the National Weather service said. Starting in the middle of the week, forecasters expect Southland temperatures to rise to above-normal levels.
