NAPA, CA — A series of storms is set to hit Northern California, signaling a continuation of a wet March for the region, according to weather officials. After a brief break in winter weather, the Bay Area and Central Coast are bracing for another round of rain, gusty winds, and chilly temperatures.
The National Weather Service (NWS) described the calm conditions of Monday as “the proverbial calm before the storm,” with mild temperatures and mostly sunny skies offering a brief respite before the incoming system.
The second storm, categorized as an atmospheric river, will bring moderate to heavy rainfall to Northern California. Although weaker than some of the systems that have impacted the state earlier this season, forecasters warned that this system will still bring significant weather impacts. The arrival of the storm is expected late Tuesday night, with its intensity increasing by Wednesday.
The first wave of rain will coincide with morning commute hours, potentially causing hazardous travel conditions. Forecasters predict 1 to 2 inches of rain in lower elevations, with the North Bay and coastal mountains receiving up to 3 inches. Thunderstorms, gusty winds, and light hail are also possible, and some areas could experience localized flooding due to heavy rainfall.
In addition to the rain, temperatures are expected to drop significantly by Wednesday. San Francisco will see a low of 46°F, while areas like Sonoma could experience temperatures dipping as low as 39°F. The NWS emphasized that a cold front will arrive early Wednesday, bringing frigid conditions and the potential for snow at higher elevations.
Wind is another major concern with the approaching storms. The NWS has issued warnings for strong south to southwest winds, with gusts reaching up to 50 mph in higher terrain. Winds in lower elevations are expected to range from 30 to 40 mph, potentially causing power outages and travel disruptions, especially in wind-prone areas.
Coastal residents are being urged to exercise caution as dangerous surf conditions are expected along the coastline. Wave heights could reach 20 feet or more by midweek, increasing the risk of strong rip currents and sneaker waves. Beachgoers are advised to stay clear of jetties, rocks, and steep beaches where large waves could strike unexpectedly.
The storm system is not expected to be the last of the rain for Northern California. The National Weather Service predicts that multiple rounds of rainfall will continue through Friday and into the weekend. As the weather pattern becomes wetter, rainfall totals could be similar to those seen in previous storms, though some uncertainty remains regarding the exact amounts.
Meteorologist Matt Mehle of the NWS Bay Area office noted that the trend has been toward wetter conditions, with more rain expected in the coming days.
As the storms move through the region, residents are advised to prepare for challenging weather conditions, including heavy rain, gusty winds, and hazardous surf. Travelers should anticipate delays, and those in coastal areas should take extra precautions as the storm system moves through.
