A severe weather system is sweeping across the United States, putting millions of Americans on high alert for blizzard conditions, tornadoes, and extreme heat.
The storms have already caused major disruptions, including flight cancellations, road closures, and wildfire risks, as communities across the country prepare for life-threatening conditions.
Blizzard Conditions Hit Northern Plains and Upper Great Lakes
A rapidly intensifying storm has triggered blizzard conditions from eastern South Dakota through Wisconsin and into Michigan’s Upper Peninsula.
As of Sunday afternoon, some areas in southeastern Minnesota and western Wisconsin had seen over 20 inches of snow, and snow-covered roadways and low visibility have made travel extremely dangerous.
- Minnesota, Michigan, and Wisconsin have issued hazardous travel warnings and no-travel advisories in some areas.
- Minneapolis-Saint Paul International Airport reported over 600 flight cancellations, and dozens more flights were canceled in Detroit.
- Snowplow drivers in Wisconsin described the conditions as some of the worst they have seen in years, with visibility near zero in many areas.
Blizzard conditions are expected to last into Monday, with additional lake-effect snow continuing to impact regions near the Great Lakes.
Severe Weather Threat Expands Across the Eastern U.S.
The same storm system is causing severe thunderstorms and tornadoes across the Midwest and South, particularly as it moves eastward.
A developing squall line is expected to bring damaging winds, hail, and flash flooding to the Lower Great Lakes, Ohio Valley, and Tennessee Valley through Sunday evening.
- On Monday, a moderate risk of severe weather stretches across the Mid-Atlantic, with particularly strong winds expected in South Carolina, Virginia, and the Washington, D.C. area.
- The weather service has issued warnings for tornadoes and damaging winds in Raleigh, North Carolina, Richmond, Virginia, and the nation’s capital, with flash flooding likely to worsen as the storm progresses.
Early Heat Wave and Increased Wildfire Risk in the West
As the eastern U.S. braces for storms, the western U.S. faces an unusually early heat wave. Temperatures are expected to climb into the 90s and 100s in parts of Southern California, the Desert Southwest, and the Great Basin. California and the interior West could experience highs in the 70s and 80s.
- The warm, dry, and windy conditions are also raising the wildfire risk in the High Plains and Western U.S..
- In Nebraska, over 30 National Guard members were deployed to combat wildfires that have already consumed more than 900 square miles. One fatality has been reported, and Governor Jim Pillen urged residents to follow evacuation orders as winds are expected to remain high.
Flash Flooding and Landslides in Hawaii
In Hawaii, flash flooding has caused significant damage, particularly on Maui, Molokai, and the Big Island. Heavy rainfall, with up to 2 inches per hour, has led to widespread flooding and landslides.
- Maui County received 20 inches of rain in 24 hours, causing sinkholes, debris, and downed power lines across the island.
- Over 30,000 customers lost power, and National Guard and fire department workers have performed multiple rescues from floodwaters.
The United States is facing a historic weather event, with blizzards in the north, tornadoes and severe thunderstorms in the east, extreme heat in the west, and flash floods in Hawaii.
Millions of Americans are under alert, and authorities are urging everyone to stay informed and take precautions as these life-threatening conditions continue to develop.
