Strong Santa Ana Winds Coming

3/11/2014, 5:15:14 AM

Weather parameters are coming together for a period of strong Santa Ana winds in Southern California Tuesday night into Wednesday.

This is looking like one of the higher end Santa Ana events of this winter with regards to wind speed. A developing closed 500 mb low over west-central and southern Nevada and easternmost California Tuesday night and Wednesday along with a surface high pressure building south are the two major contributors.

The CANSAC 2 km WRF is one of the better models to look at for these events. Here are to snapshots of what it is predicting for the 12Z Monday run.

Tuesday 4 p.m.:

Wednesday 4 a.m.:

These two maps show how the winds increase Tuesday night. The strongest winds will be late Tuesday night into Wednesday morning with widespread north-northeast winds of 25 to 50 mph with gusts to 60 mph in the areas favored by these type of winds. Winds will subside some midday and afternoon Wednesday. The wind and a dry air mass will bring a high fire danger across these areas.
