A multi-day flood threat will return to the already soaked California starting Wednesday, and could last through the weekend and potentially into next week. Unfortunately, rain will impact many New Year’s Eve outdoor festivities, so plan to bring the rain gear with you. Rain will become more widespread Wednesday night into Thursday. Locally heavy rain and scattered thunderstorms will be possible in and around the LA basin early Thursday morning. Can’t rule out an isolated tornado across Southern California, so please stay weather aware if planning to go to the Rose Parade in Pasadena.
