SANTA CLARITA (CBS) — Portions of the 5 Freeway that were shut down due to snow fall at the Grapevine Monday have since reopened, according to the California Highway Patrol.
Interstate 5 was reopened in Castaic shortly after 5:30 p.m. Both directions of the freeway were closed from Lake Hughes Road in Castaic to the Kern County line, according to the CHP.
The closure snarled traffic for hours, and the Grapevine may need to be closed again later tonight, when tempatures in Castaic will drop into the 40s and the summit will feel freezing temperatures.
Los Angeles and Orange counties had winter weather advisories in effect until 11 p.m. Monday.
Snow was expected as low as 2,000 feet, with gusts of 23 to 30 mph, causing visibility problems in the mountain areas.
Riverside County was under a winter storm warning until 3 a.m. Tuesday with an expected snow fall of 3-8 inches.
San Bernardino County was also under a winter storm warning in effect until 10 p.m. Monday.
Rain was expected to increase heavily into Monday evening, according to the National Weather Service.
Hail was reported in the San Fernando Valley and Orange County during the early afternoon.
By 11 a.m., most of the rain was moving to the north of Los Angeles and snow was falling in some mountain communities. Rainfall totals will range from .10 to .66 of an inch.
Snow is expected to start falling at the 4,000-foot level before dropping to about 2,500 feet late Monday. Two to six inches of snow are possible.
Gusts up to 60 mph are possible in Inland Empire and mountain areas.
Temperatures are expected to remain in the mid-50s for most areas through Wednesday, and then climb into the 70s by the weekend.
