California – Authorities issued severe weather warnings across Northern and Central California on Tuesday as a powerful atmospheric river unleashed heavy rain, damaging winds, and mountain snow. This is the first in a series of storms expected to impact the Pacific Northwest later this week, according to AccuWeather senior meteorologist Heather Zehr.
The National Weather Service (NWS) cautioned residents that the storm could bring moderate to heavy rainfall, flooding, gusty to high winds, and mountain snow through Wednesday.
Understanding Atmospheric Rivers
Atmospheric rivers are described by the National Oceanic and Atmospheric Administration (NOAA) as “long, narrow regions in the atmosphere—like rivers in the sky—that transport most of the water vapor outside of the tropics.” These storms are most common on the West Coast, particularly during the winter months, and can produce both beneficial snow for reservoirs and hazardous conditions.
Storms brought by atmospheric rivers are capable of triggering deadly flooding, mudslides, and widespread power outages, making them a major concern for residents in affected areas.
California’s Wet Season and Current Impacts
California’s wet season typically begins in October, and the state has already seen multiple storms as cooler weather sets in. This current system has caused high wind warnings, with gusts of up to 65 mph reported, capable of knocking down trees and power lines.
As of Tuesday, more than 8,000 people are without power in Northern California, according to poweroutage.us. The NWS San Francisco office emphasized that widespread power outages are possible and warned that travel could be extremely difficult and hazardous, particularly for high-profile vehicles.
Mountain Snow and Flooding Threats
The storm is also expected to bring mountain snow to parts of the region, which could accumulate rapidly in higher elevations. Combined with heavy rainfall, this increases the risk of flooding and mudslides, particularly in areas already saturated from previous storms.
Officials are urging residents to follow local weather advisories and remain vigilant as the storm progresses. Weather alerts are expected to remain in place through Wednesday, with emergency crews prepared for power outages, downed trees, and road hazards.
Safety Tips for Residents
Residents in the affected areas are encouraged to:
- Avoid unnecessary travel during high wind and heavy rain conditions.
- Secure outdoor items that could be blown away.
- Stay updated with local weather reports and advisories.
- Prepare for power outages by charging devices and keeping emergency supplies on hand.
The atmospheric river highlights the double-edged nature of California’s storms, providing much-needed water for reservoirs while also posing significant dangers to life and property.
