Los Angeles officials say action is being taken to stem the flow of toxins into California's water supply ahead of rain forecast for the weekend.

While areas of Los Angeles County are still under mandatory evacuation orders, Southern California gets a "much-needed" reprieve from fire weather conditions. But, the break will likely be short-lived as "dangerous fire weather conditions" are forecasted to pick back up again the following week, according to the National Weather Service, NWS.
