Arctic Blast Grips US While Northwest Floods Linger
13 Dec
Summary
- Arctic air moves south from Canada, affecting northern U.S.
- Pacific Northwest braces for mudslides and levee failures from floods.
- Dangerous wind chills reach minus 33 F in Grand Forks, North Dakota.
A significant blast of arctic air is sweeping southward from Canada, bringing frigid conditions to much of the northern United States. This cold snap is causing dangerous wind chill values, with temperatures feeling as low as minus 33 degrees Fahrenheit in Grand Forks, North Dakota.
Simultaneously, the Pacific Northwest is enduring further misery from extensive flooding caused by an atmospheric river. Thousands of residents have been forced to evacuate their homes as rivers have swelled, inundating communities. Authorities are warning of continued dangers from potential levee failures and mudslides as floodwaters are slow to recede.
The severe weather systems pose a dual threat, with the cold air mass expected to expand into southern states by Sunday. In the Pacific Northwest, despite some receding waters, the risk of further damage remains high due to lingering high water levels and the threat of more rain.
