Finally the much needed rain is coming to the Oroville and Northern California areas but at the fire affected areas it could cause ash and debris flow, clogging culverts, and leading to localized flooding. Monitor your surroundings this weekend if you live near burned areas.
An early season Pacific storm system will be moving through northern California this weekend. The main cold front will be moving through Friday evening through Saturday. This will be the period of heaviest precipitation. The strongest wind with this system is expected Friday afternoon and evening. Per US NWSSacramento
