‘Critical fire conditions’ expected across region while much-needed rain raises fear of toxic ash runoff

Parched southern California was forecast to face more dangerous winds on Wednesday but could get some needed rain this weekend, easing fears for another round of deadly wildfires while raising the possibility of challenges like toxic ash runoff.

Los Angeles officials were preparing for that prospect even as some residents were allowed to return to the devastated Pacific Palisades and Altadena areas. Firefighters extinguished small blazes that broke out during gusty weather expected to last through Thursday.
