Next Round of Rain on the Way

The rain that doused the Southland over the past  week is gone, but more could arrive Tuesday night and Wednesday, according to the National Weather Service.

A fast-moving Pacific storm system is expected to pass through the  region on Wednesday, with showers developing from the northwest Tuesday  evening.

With the ground already soggy, and some roads still closed because of  flooding and debris flows, the additional rain could cause more problems,  especially in the burn areas. Preliminary rainfall estimates are a half-inch to an inch along the  coast and in the valleys, with up to two inches in the mountains.

Four to 8 inches of snow could fall at the higher elevations.

Snow levels will "plummet'' Wednesday night and early Thursday, as very  strong northerly winds will bring some of the coldest temperatures of the  season to the region, according to the Weather Service.

Temperatures on Thursday and Friday will be 5 to 15 degrees below  normal, with some mountain and desert locations dipping to 20 degrees below  normal.

Wind, Snow in Tejon Pass

The storm is forecast to bring winds and snow in the Tejon Pass and other north-facing mountain areas  Wednesday and Thursday. Gusting winds up to 70 miles per hour are possible overnight Wednesday  into Thursday in the mountains of Los Angeles County, Rorke said.

The conditions could make for an unpleasant couple of days in the  mountains, especially for motorists on the "High 5" sections of the Golden  State Freeway in northwest LA County, Rorke said.
