LOS ANGELES (FOX 11) - An early morning storm drenched parts of Los Angeles County, but is expected to clear by this afternoon.
The storm reached the county shortly after midnight and could produce between a half-inch and an inch of rain, National Weather Service Meteorologist Andrew Rorke said.
No serious flooding, debris flows or mudslides are expected as a result of the system -- but they are not totally inconceivable.
The Woolsey fire zone in Ventura and Los Angeles counties will be the area of greatest concern, Rorke said, and the threat will increase if thunderstorms develop.
The greater risk could come next week, beginning Sunday, when a series of storms slide in "one after the other" through Thursday, possibly producing 2 to 4 inches of rain, Rorke said, indicating three weather systems may be involved.
"We're expecting 12 to 18 hours of dangerously heavy rain," he said. But with various models in conflict, it's not possible to say when or where that dangerous period will take place, Rorke said.
Los Angeles County officials are cautioning residents of recent burn areas such as the Woolsey, Creek and La Tuna fires to monitor local news outlets, avoid driving through moving or ponded water and report storm-related emergencies to (800) 675-HELP (4357).
County officials encouraged some residents to consider evacuating the area in advance of the storm.
"Peak rainfall rates may result in significant mud and debris flow, and we encourage Woolsey Fire survivors to be ready to evacuate at a moment's notice," county Fire Chief Daryl Osby said, referring to the wildfire that ripped through the Malibu area. "Elderly residents, individuals who have medical conditions and residents who own large animals should make plans now to leave their homes as a precaution."
