Are you ready for the biggest storm of 2021?

Updated: Mar 31

The National Weather Service has announced an atmospheric river that will bring light to heavy rainfall to the Bay Area from today until Thursday. Rainfall is projected to come in two parts. There will be light to moderate showers from now until Tuesday, and a 2.5-11 inch downpour in the following two days.

Location is everything for determining how this rain event will affect the area. Urban locations are predicted to receive 2.5-4.5 inches of rain, where higher elevations could see 4-7 inches. Mountainous regions could receive as much as 9-11 inches of rainfall.

This much rainfall is great for our dry state, yet has the potential to cause mudslides and erosion, particularly in areas that were scorched by the recent fires of fall 2020. Minor flooding is another potential side effect of such a large storm.

Construction sites in this region are prone to the above setbacks. To prevent that from happening, we recommend to protect all disturbed soil areas with proper erosion control measures. Consult with your site QSP to make sure all necessary BMPs are in place.

Button up your sites and rain coats alike; it's gonna be a big one.
