Wondering why it is so windy today, well the surface pressure gradient has steadily been dropping between SFO and SBA this morning, and is currently -15.8 mb. #CAwx 

@KonaTheFighter  Pressure gradient is the difference in pressure between two stations (in this case, San Francisco and Santa Barbara). Greater absolute values in pressure gradient means wind speeds are higher.

Looks like winds will start diminishing around 4 PM.

While the rain has largely ended wind is going to be a BIG concern this afternoon. Given saturated soil falling trees and power outages are *likely*. Please remain vigilant and avoid unnecessary travel. Stay safe! #cawx

As we prepare for the incoming weather lets take a moment to pause and look at the visible imagery and marvel at what Mother Nature is sending our way.

Highway 101 has turned into a moving river this afternoon. Do not drive into these flood waters, putting yourself and everyone around you at risk. #TurnAroundDontDrown  #CAwx  #CAflood 

🛰Marvel at the satellite imagery this morning. Those asking, "Where's the Storm"? It's still coming. The rain this morning is not the main event so to speak. Heavier rain is expected later today. Blue dots are lightning flashes. #cawx 

Tomorrow, Jan 3, is your last day to do storm prep before heavy rain & strong winds arrive Wed-Thu. Here's a list of things to think about. Visit for more info. #cawx  #BayArea
