Pacific Northwest Braces for Continued Flooding as Atmospheric River Impacts Region
A powerful atmospheric river continues to unleash torrential rainfall across the Pacific Northwest, triggering widespread evacuations and disrupting travel in both the United States and Canada. Residents are facing rising floodwaters and officials are urging caution as the region prepares for another potential storm this weekend.
Current Situation: Evacuations and Closures
Evacuation orders are currently in affect for several communities. In Washington state, Sultan is actively conducting evacuation efforts, as seen in images of first responders assisting residents. Across the border in British Columbia, Canada, the communities of Tulameen and Eastgate are under evacuation orders, alongside several other affected areas.
Specifically, the City of Abbotsford issued urgent evacuation notices late Wednesday for 371 properties, anticipating overflow from the Nooksack River. While officials don’t expect flooding to reach the severity of the 2021 event – which tragically resulted in five deaths and meaningful damage – they are taking proactive measures.
Travel throughout the Lower Mainland has been severely impacted. All major highways are currently closed, and the US-Canada Sumas Border crossing is shut down in both directions. You can find the latest travel updates on Drive BC‘s website.
Understanding Atmospheric Rivers
What exactly is an atmospheric river? essentially, thes are concentrated bands of moisture in the atmosphere.They form when water evaporates and is carried by the wind, creating long, flowing currents in the sky – much like rivers on land. These rivers can deliver significant amounts of precipitation when they make landfall.
What to Expect in the Coming Days
The heaviest rainfall is expected to diminish by Thursday afternoon. However, rivers will continue to swell as runoff from the storm makes its way downstream. This means the risk of flooding will remain elevated for several days.
Unfortunately, this isn’t a one-time event. Another storm system is forecast to arrive on Sunday, potentially bringing further rainfall and exacerbating the situation.
Staying Safe and Informed
If you live in an affected area, it’s crucial to stay informed and heed the advice of local authorities. Here are some key steps you can take:
* Monitor local news and weather reports: Stay updated on the latest forecasts and evacuation orders.
* Prepare an emergency kit: Include essentials like food, water, medication, and a first-aid kit.
* Know your evacuation route: Familiarize yourself with designated evacuation routes in your community.
* Secure your property: Move valuables to higher ground and take steps to protect your home from flood damage.
* Never drive thru floodwaters: Even a small amount of moving water can be dangerous.
