'Significant storm event' brings heavy rain, wind to LA

Los Angeles is experiencing its first "significant storm event" in three months.

According to the National Weather Service, this Pacific storm system is bringing an atmospheric river moisture source with it, resulting in significant rainfall in our area late Sunday into Monday. 


Flooding was reported Monday morning on some roadways, and officials reminded the public to drive with their headlights on, slow down, and avoid slamming on the brakes in the event their vehicle is hydroplaning.

Here's what you need to know.

When is the storm coming?

According to latest rain estimates for the upcoming storm system, rain is expected to start in San Luis Obispo Sunday afternoon and continue to travel south and reach Los Angeles by Sunday night. 

Showers and maybe even some thunderstorms are expected to continue into Monday, so early morning commuters are advised to leave early as traffic delays are expected due to the wet commute.

How much rain will we get?

"Most areas will get a soaking, which is needed," the National Weather Service said. 

Officials said most coastal and valley areas will see somewhere between -.50-1.5", while the foothills and mountains will see 1-3" between Sunday and Monday night.

What about snow?

Snow will only be an issue at higher elevations with Monday's storm, the National Weather Service said. 

Snow levels are likely to be above 7,000 feet dropping late Monday, the agency said, while elevations above 6000 feet may get 6-10".

At this time snow is not expected to impact I-5 or I-15 due to the initial high snow level.

Local street flooding is possible.
