Got the following from the LA County Dept. of Public works:

The Los Angeles County Department of Public Works has announced that based on the forecast of heavy rain, it will close public access to all County roads within the Station Fire burn area at 11:59 PM Saturday, March 19, 2011. 

As a result, the following roads will be closed to all traffic with the exception of emergency vehicles, including Public Works personnel: 
• Angeles Forest Hwy from Aliso Canyon Road to SR-2 (Angeles Crest Hwy) 
• Big Tujunga Canyon Road from the City of LA/County boundary to Angeles Forest Hwy and 
• Upper Big Tujunga Canyon Road 

Local access will not be permitted until the road closures are lifted. 

The closure will be in effect until we can make the roads safe for passage. 
Residents can also visit the CARE website at www.dpwcare.org for further updates on road conditions or sign up through Public Works’ eNotify system to receive instant notifications. 

Residents, business owners and persons with access or functional needs may also call 2-1-1 for LA County information and referral services regarding post disaster resources that are available to those affected by the floods and debris and mud flow.
