A powerful storm system known as the ‘Pineapple Express’ is about to drench the western U.S. with heavy rain and dump feet of snow on mountain ranges. Expect dangerous flooding, mudslides, road closures, and potential power outages. Residents in California and surrounding states are being urged to stay alert and prepare for disruptions.
What Is the ‘Pineapple Express’ and Why Is It a Threat?
The ‘Pineapple Express’ is an atmospheric river—a stream of warm, moisture-packed air that flows from the tropical Pacific near Hawaii and slams into the West Coast. This current of moisture is notorious for bringing excessive rainfall, and that’s exactly what’s in store for much of the region this week.
Northern California will see the heaviest rain, with 2 to 6 inches expected over several days. Some spots could see even higher totals. With soils already saturated from previous storms, flood risks are high. Rivers could overflow, and mudslides are possible in areas with steep terrain and burn scars. The Sierra Nevada is bracing for feet of snow, making travel difficult. Whiteout conditions, avalanches, and road closures are likely in higher elevations.
How Bad Could It Get?
Flood watches are in effect across large areas of northern California. The National Weather Service warns that flash floods, river flooding, and mudslides are all real threats. Major highways and mountain passes could experience closures due to ice, snow, and debris flows. Strong winds could knock down trees and cause power outages.
What You Can Do to Stay Safe
Check local weather forecasts regularly. Avoid unnecessary travel, especially in flood-prone areas. Have an emergency kit with supplies in case of power outages or evacuation orders. Be aware of evacuation routes if you live near steep hillsides or recent burn areas.
This storm system is expected to be a high-impact event, and preparation will be key to staying safe.
