The National Weather Service issued a hazardous weather outlook Monday and warned that rain, wind and possibly hail could hit the region Tuesday as a cold stormfront moves in.
The inclement weather is expected to last through Wednesday and NWS predicts that scattered thunderstorms could produce small hail in addition to the 80 percent chance of rain forecast for Tuesday.
The Los Angeles County Public Works Department said Sunday that it may close Angeles Forest Highway from Aliso Canyon Road to Angeles Crest Highway, effective Tuesday, said Sgt. Burton Brink of the Crescenta Valley sheriff's station.
Additional closures include Big Tujunga Canyon Road from Angeles Forest Highway to Vogel Flats and Upper Big Tujunga Canyon Road from Angeles Forest Highway to Angeles Crest Highway.
"Local access will not be permitted until the road closures are lifted,'' Brink said. "The closures will remain in effect until the storm system has passed and the roads have been inspected."
