High Wind Warning

The National Weather Service has issued a High Wind Warning for the San Gabriel Valley. This warning will be in effect from 3:00pm this afternoon until noon tomorrow. Damaging winds are expected mainly in and near the foothills. Potential impacts: With the soil loosened by recent heavy rains, trees will be more easily uprooted by the strong winds. The very strong winds will be capable of producing downed power lines and causing power outages.

Stay clear of all downed lines and report any hazards to the Sierra Madre Police Department.

Sierra Madre Police Department: 626-355-1414 (911 for emergencies).


Updates will be issued on SMTV3 (Time Warner-channel 3), Sierra Madre Community Radio (AM 1630), and the City’s Emergency Blog (http://sierramadrepio.blogspot.com).
