Another round of rain and snow arrived in drought-stricken Southern California Tuesday night and continued through Wednesday afternoon, forcing road closures, bad driving conditions and downed power lines.
SoCal's second wave of precipitation made landfall Wednesday evening. Some NBC4 viewers reported heavy rain and loud thunder in the San Fernando Valley. Thunderstorms could produce gusty winds and hail.
The first round of the much-needed rain showers began about 11 p.m. Monday and continued steadily through the next day.
Strong winds, rain and a possible lightning strike forced power lines to fall in Sunland late Wednesday afternoon, leaving at least 750 LADWP customers without power.
Snow was reported in the San Bernardino mountains, and snow levels were expected to drop to as low as 3,000 feet.
Drivers were advised to travel cautiously, especially along the Golden State (5) Freeway through the Grapevine and other mountain roadways as snow showers were expected above 3,000 feet.
Light snow fell in the Frazier Park area along the Grapevine early Wednesday.

The LA Department of Public Works closed access to Angeles Forest Highway from Aliso Canyon Road to Angeles Crest Highway, as well as Upper Big Tujunga Canyon Road from Angeles Crest Highway to Angeles Forest Highway as of midnight Wednesday.
Local access to the roads will not be permitted until the storm system has passed and roads have been inspected.
Between Monday and Wednesday, the storm was expected to generate between a quarter and three quarters of an inch of rain, with 1 inch possible across southwest-facing mountain slopes and near the sites of any thunderstorms, forecasters said.
Residents in recent burn areas above Glendora and Azusa were advised to monitor the forecasts as heavy downpours could bring the threat of minor mud and debris flows. The storm comes about a month after a larger one spurred evacuation orders for more than 1,000 homes in the cities in northeastern Los Angeles County, and about 2 1/2 months after a wildfire left them stripped of vegetation and made them vulnerable to collapsing hillsides.
The storms come amid long-term drought conditions in California. The first significant storms in months brought rain to California in late February and early March, but persistent dry conditions prevailed since then, reducing the rainfall's benefits for the drought-stricken region.
Since December, 4.47 inches of precipitation have been reported in California. The average for that period is 11.73, according to the National Climatic Data Center. The state has received 7.53 inches of precipitation since June, about 9 inches below the average for that nine-month period.
