Southern California was cleaning up Monday morning after a heavy storm that produced record rain totals in parts of the region.

Numerous roads remained closed Monday morning, including Interstate 5 through the Grapevine, due to snow, and Pacific Coast Highway at Point Mugu. A separate stretch of PCH in Malibu was reopened.

[Updated, 9:13 a.m.: All lanes along the Grapevine were reopened, and cars were being escorted by the California Highway Patrol.]

Topanga Canyon Road also was closed, as was Angeles Forest Highway (see full list of road closures in Los Angeles County here).

Some areas of L.A. County were hammered by the storm, including Van Nuys and Newhall, which recorded more than 6 inches of rain. Canoga Park recorded 4.7 inches; Beverly Hills, 4.1; and UCLA, 3.2.

Though the main rainstorm has moved on through the area, the National Weather Service said scattered showers were expected Monday, with another storm arriving Wednesday.

Strong winds at Bob Hope Airport in Burbank caused Southwest Airlines to cancel 16 flights Sunday and divert at least eight flights, and other airlines experienced long delays, an airport spokesman said.

Snow accumulated on the Grapevine and in the Ventura County mountains, with as much as 27 inches at the Pine Mountain Club in Kern County and 19 1/2 inches in Lockwood Valley, according to Stuart Seto, a weather specialist with the National Weather Service in Oxnard.

Residents from 12 homes in Woodland Hills were evacuated Sunday night as a flow of debris and mud threatened a retaining wall in the area, according to the Los Angeles Fire Department.
