Severe Rain Storms Continue To Threaten The Los Angeles Area

WRIGHTWOOD, CA - JANUARY 23: Fresh-fallen snow blankets desert foothills and forested mountains on the north side of the San Gabriel Mountains on the morning after the fourth storm of the week dissipated on January 23, 2010 northwest of Wrightwood, California. Thousands of people were evacuated this week in the Los Angeles-area foothill cities because of fears of possible major mud slides and debris flows from mountains where wildfires occurred in 2008 and 2009. The threat was highest along the south side of the San Gabriel Mountains which were denuded of natural flood-controlling vegetation by the 250-plus square mile Station last year.
