At 2:16 pm today (Friday, Feb. 24) the National Weather Service in Oxnard issued a flash flood warning for large swaths of Santa Barbara, Ventura and Los Angeles counties.

The loud, impossible to ignore alert was distributed to cell phones all across the region (and outside areas of concern) via the Wireless Emergency Alert System.

"Think of it as flooding but you turn up the dial. It's a bit more dangerous," said Lisa Phillips, meteorologist with the NWS who issued the alert.

What to know about these warnings

Here's an excerpt from our guide to understanding flood warnings:

  • Flood advisories are how the NWS begins to raise the alarm. The goal is to give people enough time to take action.
  • Flood watches are your indicators to get prepared to move.
  • A flood warning is issued when a hazardous weather event is imminent or already happening. When one is issued for your area, you need to get to higher ground immediately.
  • A flash flood warning is issued when a flash flood is coming or in progress. Flash floods are sudden and violent floods that can start within minutes.

"If you can't see the ground beneath you, when you're driving, don't drive through that area."

From our guide: What You Should Do If You End Up Driving In A Flooded Area

According to the National Weather Service, just 12 inches of rushing water can carry away most cars, and two feet can carry away SUVs and trucks.

Flooded roads can cause a vehicle to stall and severely damage it. Water can flood the engine, warp the brake rotors, make you lose power steering and even short out the electrical components.
