Officials said houses in warning areas considered to be high risk will get a visit from LAPD today to issue specific evacuation orders. A flyer will be left at the door if you aren't home.

Road Closures:

Caltrans announced that it will be closing a portion of Pacific Coast Highway because of the upcoming storms. Starting on Wednesday at 12 p.m., the highway will only be open to emergency vehicles and the U.S. Army Corps of Engineers contractors. 

Officials hope to reopen the road by Friday at 6 a.m., though it could come sooner.

What we know:

The atmospheric river will begin slamming the region beginning Wednesday evening. 

"We’re definitely tapping into all of that moisture that’s coming in from the South and Southwest. We’ve got very cold unstable air mass getting ready to move over us and that’s going to translate to some really stormy weather as we get into the remainder of today, particularly as we get into tonight and during the overnight hours," explained FOX 11 Meteorologist Maria Quiban.

In addition, the powerful storm could trigger some rare weather events in the region.  

"We could get some thunderstorms and with those thunderstorms, there’s a potential for some weak tornadoes, some small hail and very strong, gusty winds," Quiban added. 

How much rain/snow is expected?

By the numbers:

The amount of rain expected varies.

"Fullerton could get an inch and a half or a little bit more than that by Thursday morning, one inch, maybe a little bit more than that for downtown LA through early tomorrow morning and then six-tenths of an inch in Riverside." 

In terms of snow, up to two feet of snow is expected at higher elevations. 

What they're saying:

"While we prepare for another storm headed towards L.A., I want to urge Angelenos to stay vigilant, especially in burn scar areas" said Mayor Karen Bass. "My number one job is to keep Angelenos safe, so please heed all evacuation warnings, stay vigilant and stay informed."

How to request support

What you can do:

In the event of a life-threatening emergency, call 911.

For impacts like roadway flooding, tree limbs blocking roads, or mudslides, LA residents should request service through MyLA311 or by calling 3-1-1, which will operate overnight Wednesday and into the early morning hours on Thursday. You can also download the MyLA311 app.

In the event of power outages or water main breaks, Los Angeles Department of Water and Power customers can call 1-800-DIAL-DWP. If you see a downed wire, always assume it is live. Never approach or touch any wire that is down or dangling and immediately report it by calling 9-1-1.

What's next:

Conditions are expected to clear out in time for the weekend, before another opportunity of rain emerges Monday.
