The 5 Freeway in Castaic was re-opened in both directions Thursday afternoon after a full closure due to snow in the Grapevine, while flooding and numerous road closures were reported in Santa Clarita throughout the day during a rainstorm.

UPDATE 3:15 p.m. – The 5 Freeway is now open in both directions after a six-hour closure, according to CHP.

UPDATE: 2:15 p.m. – The 5 Freeway has been re-opened on the southbound side, according to CHP Fort Tejon officials. Motorists are encouraged to drive carefully, as the roads are still wet.

The northbound I-5 remains closed to traffic through the Grapevine starting at Parker Road in Castaic, according to Caltrans.

UPDATE: 11:40 a.m. – CHP Newhall has issued a possible “Operation Snowflake” closure warning for the Escondido Summit on State Route 14 and other low elevation mountain passes and portions of the Antelope Valley as well as Acton/Agua Dulce areas, respectively, due to snow accumulations and icy road conditions.

On very rare occasions the snow level has dropped low enough to require the closure of SR-14 in Acton/Agua Dulce areas.  Motorists who plan on traveling through the area should familiarize themselves with potential alternate routes.  Generally, alternate routes for travelers are SR-126 to US-101 to SR-166 to I-5, or SR-14 to SR-58 to SR-99. At this time, this is a closure warning ONLY.

Residents of the Santa Clarita Valley and Castaic, specifically, should prepare for additional vehicular traffic on surface streets as traffic may be channeled off the freeways.  In the event Operation Snowflake is implemented, CHP highly recommends staying home if you don’t have to use the roads.

UPDATE: 11:20 a.m. – California Highway Patrol is in the process of shutting down all canyon roads connecting the Antelope Valley to Santa Clarita due to weather, including: San Francisquito Canyon, Bouquet Canyon, Lake Hughes Road and Highway 138.

UPDATE: 11:07 a.m. – Sierra Highway has just reopened after flooding which caused evacuations in Canyon Country.
