A powerful mid-latitude cyclone is set to impact the West Coast of the United States this week, bringing a substantial atmospheric river to Oregon and California. This storm system is undergoing bombogenesis, characterized by a significant and rapid drop in atmospheric pressure, and is projected to experience a remarkable decrease of 50-60 millibars in less than 24 hours.
This impending storm, expected to hit between Tuesday and Thursday, will deliver substantial rainfall, strong winds, and large ocean swells, with the Northwest and northern California likely facing the brunt of the effects. The Weather Prediction Center has issued a HIGH RISK alert for excessive rainfall in parts of Northern California, with forecasts suggesting that some areas could receive over a foot of rain. This could result in severe flooding, including river and flash floods.
Residents in flood-prone areas are advised to be prepared for potential evacuations if flash flood warnings are issued. Coastal regions may also experience strong winds capable of uprooting trees and downing power lines, particularly from Tuesday into Wednesday. The storm’s severity is highlighted by its extreme categorization on the Atmospheric River (AR) scale, indicating potentially hazardous conditions. However, in certain areas, this rain could be beneficial.
Additionally, Winter Storm Warnings are in effect for the higher elevations of Northern California, anticipating heavy snowfall through Wednesday.
Stay informed with regular updates from WeatherNation both on air and online regarding this significant weather event.
Summary: An intense cyclone is forecasted to bring heavy rain and strong winds to the West Coast, particularly affecting Oregon and California. With advisory warnings in place for floods and severe weather, residents in vulnerable areas must remain vigilant. However, the system might also produce beneficial rainfall in certain locations.
This serves as a reminder of nature’s power, and with proper preparedness, communities can mitigate potential risks.
