About those advisories

Winter storm warning

High winds
Several portions of SoCal are under high wind warnings and wind advisories. Let's break it down.

Meteorologist Andrew Rorke with the National Weather Service said high wind warnings have been issued for the L.A. and Ventura county mountains until noon.

"Warning level winds in the mountains and Santa Clarita valley from 60 to 70 mph will be common for a four to five hour period," he added. "Below the mountains and in most of the valleys and coasts... advisory level winds of 35 to 45 miles per hour will also be common."

Riverside County mountains will see strong wind gusts between 30 to 40 mph, and up to 70 mph through the morning.

The San Bernardino County mountains are experiencing similar wind gusts.

Coastal Flooding and High Surf
L.A. and Orange county beaches are seeing high surf that could result in minor coastal flooding, though not as severe as just before New Year’s.

Minor coastal flooding could occur during morning high tide where local sets up to 11 feet are expected for Orange County beaches, whereas over in L.A. County beaches, large breaking waves up to 10 feet are expected — mainly for west facing beaches.

Take precautions at the beach and avoiding swimming as the strong rip currents can be hazardous.

This day in history

On this day in 2005, the Pineapple Connection, an atmospheric river, brought heavy downpour to Riverside, San Bernardino, Orange County and San Diego. A total of 31.75 inches of rain fell in Lake Arrowhead.
