Back-to-back powerful Pacific storm systems to impact the Pacific Northwest and northern California through the end of this week with heavy rain, flooding, strong winds, and higher elevation mountain snow. A strong, long-duration atmospheric river will accompany the Pacific storms, bringing excessive rainfall and flash flooding to southwest Oregon and northwest California through the week. Read More >

Early Season Storm Brought Historic Heavy Rains and Strong Winds to the Bay Area
|
The 2020/2021 Water year ended unceremoniously in the Summer of 2021 with a "status quo" report with little rain during the rainy season leaving dry fuels around the state keeping the region on edge during Fire Season. As the 2021/2022 water season began, the pattern shifted bringing a series of upper level troughs through mid-October toward the Pacific Northwest. As these systems moved toward the California Coastline, it brought light rain in the form of cold fronts along with atypical above average accumulations to the North Bay. By October 18th, long-range models were indicating yet another low that would approach the Pacific Northwest bringing a chance for rain to the Bay Area. However, these model runs depicted a longer stream of moisture that was tapped into the sub-tropics. By the 20th, models were hinting at the chance for a high to moderate "atmospheric river", or AR, event with precipitable water values several standard deviations above the norm. There was reason to doubt initial model runs given that this type of an event is unusually early for the region. But as the event grew closer, it became more and more apparent that the Bay Area was to prepare for a substantial rain event. As the parent low pressure system moved toward Seattle and its central pressure rapidly intensified, undergoing bomb-cyclogenesis. Light showers already were showing up in the North Bay late on the evening of October 23rd. As the sun rose on the 24th, the water content increased exponentially bringing moderate to heavy rainfall around the Bay Area. Winds out of the southwest increased causing a Wind Advisory to be issued for the entire Bay Area. At higher elevations, winds were observed between 50 to 60 mph with peak gusts between 70 to 80 mph, with gusts at KSFO measured up to 50 mph. Flood Warnings and Flood Advisories were issued throughout the day from the North Bay, down the San Mateo coastline for flood risks in urban locations and small streams. A Flash Flood Warning was issued for the Glass Fire burn scar due to a period of intense rainfall rates. Storm reports that were submitted included flooding, downed trees, power outages, and some minor mud slides. By day's end, October 24th, 2021 will go down as the wettest day for many cities around the Bay Area, setting records along the way. For more information on record rainfall, see the 'Heavy Rain' tab below. The deep low pressure system driving the atmospheric river also generated historically large and powerful waves along the west coast from Washington to California. Buoys situated along the coast reported significant wave set heights of around 30 feet along and in the wake of the storm, with peak individual wave heights of 50 to 60 feet, making this wave event the 2nd largest in the 23 year history of the Point Reyes (46029) CDIP buoy (Dec 2015 was larger). An early season high surf warning was in effect as these energetic, large waves crashed into our coastline and overran many of our west to northwest facing beaches on Monday the 25th. In addition, excessive runoff from the previous 24 hours of stormy weather led to an overly brown hue to the waves. Forecasters past and present made similar observations of this wave event: while the breaking waves were indeed very large, they were not the absolute largest waves they had observed around the region. Instead, the amount of big wave energy running up the coast/beaches struck forecasters as most impressive. For example, at Carmel Beach, water overran the majority of the beach Monday morning and rhythmically splashed against the sea wall well at the opposite end of the beach. Similar scenes played out elsewhere as many beaches were still transitioning out of their less resilient summer configurations (ie, not as steep, lacking significant sand bars) when this very large, very early season event arrived. The atmospheric river gradually moved southward toward Los Angeles on the 25th.

Atmospheric River October 24-25, 2021
Rain started late on Saturday the 23rd, but the main event was forecast for Sunday the 24th, before slowly diminishing as the system moved toward Southern California. Higher elevations of the North Bay received over a foot of rainfall, with most lower level areas receiving 5" to 10" increases, helping to quell the risk of fire season. Flood Warnings and Flood Advisories for urban and small stream flooding as well as a Flash Flood Warning for the Glass Fire burn scar were.

Gusty Southerly Winds
Strong south-southwesterly winds were along the leading edge of the atmospheric river. Winds aloft were at their strongest, causing wind gusts at higher peaks and ridges from 70 to 80 mph max. As wind gusts increased at the surface, it prompted the issuance of an Airport Weather Warning at KSFO due to wind gusts between 45 to 50 mph for several hours. Widespread reports of downed trees and powerlines came as a result of the high winds.

Debris/Mud Flows and Flooding
The heavy rains lasted for over 24 hours in some areas. The rains saturated the earth and loosened leaves, twigs and low lying debris. Strong winds resulted in some areas receiving power outages. Flooding brought hazardous conditions to roadways, blocking some lanes forcing drivers to find alternate routes. In other cases, the rain moved the earth enough to create minor mud flows leaving organic debris in their wake.

Large Swell Arrived with the Storm
Buoys situated along the coast reported significant wave set heights of around 30 feet along and in the wake of the storm, with peak individual wave heights of 50 to 60 feet. An early season high surf warning was in effect as these energetic, large waves crashed into our coastline and overran many of our west to northwest facing beaches.
