Heavy Rain Headed for SoCal

15 Feb 2017, 3:58 am

It’s been a difficult week for flooding in California, and another storm system is barreling down on the west coast. Mandatory evacuations have been lifted for the Oroville Dam, but preparations are underway to reinforce the infrastructure to handle more rain and snow that is on the way.

Officials in southern California are also bracing for the threat of heavy precipitation.

Here’s how it shakes out:

A potent mid-level trough will dig south into the end of the work week. This will provide large scale lift and energy.

Rain and snow will creep south by Thursday night. Initial activity will be light.

Winds will begin increasing into Friday morning as a front edges in from the Pacific. Precipitation will only get heavier and more widespread as the front comes on shore into Friday night.

Once the front passes, the intensity of the storms will diminish. However, the forecast will stay cloudy and rainy through Saturday. Things will finally dry out a bit on Sunday, but another wave is possible by early/middle next week.

Between the heavy rain and strong winds, multiple threats will impact Southern California:

  • Flash flooding, river flooding, debris flows and mudslides
  • Damaging winds could cause downed trees and power lines
  • Travel delays due to limited visibilities and slick roadways
  • Large, dangerous surf; rip currents
  • Snowfall levels could drop as low as 6000 feet by Friday night
