  • Expecting 4"-7" in our coastal hills, 3"-5" in the North Bay, 1"-2" for the rest of the Bay Area.
  • Soil is saturated and runoff will occur quickly. Roads, smaller streams and creeks will see flooding.
  • Shallow landslides will likely happen (think mud on roads and not necessarily massive boulders).
  • Currently, none of our rivers have a high chance of flooding.
  • Flood Watch in effect for the entire Bay Area

TIPS: How do you recover from hydroplaning?

So you hit a puddle while driving and now you're hydroplaning. Don't panic -- here's what you need to do:


  • Gusts up to 45 mph possible in the afternoon and evening.
  • In the Santa Cruz Mountains we could see gusts up to 60 mph.
  • Saturated soil is like oatmeal. Trees have no stable surface and will come down easily.
  • Power outages are likely in areas, especially in the Santa Cruz Mountains.
  • Wind advisories and warnings are in effect


  • Winter Storm Watch for the Sierra starting Wednesday morning
  • 1-2 feet of snow above 6,000ft
  • 3 feet of snow on highest peaks
