Megastorm Threatens 200 Million in the U.S.: Could Become a Bomb Cyclone With Blizzards and Severe Storms

Megastorm 2026 threatens the United States

Risk of bomb cyclone

200 million people under threat

A powerful storm system is expected to intensify rapidly between Sunday and Monday as it moves across the central United States.

The system could become one of the most impactful weather events of the year due to its size and severity.

As the storm evolves, strong winds, rain, thunderstorms, snow, and cold air are expected to affect large parts of the country.

Nearly 200 million people in the central and eastern United States could feel its direct or indirect effects as the 2026 U.S. megastorm develops.

Potential Bomb Cyclone and Explosive Intensification in the United States

Meteorologists warn that the storm has conditions favorable to develop into a Bomb cyclone.

This phenomenon occurs when a storm’s central pressure drops dramatically within 24 hours.

According to meteorologist Bernie Rayno from AccuWeather, the rapid intensification could produce a large and powerful wind field.

“That rapid strengthening would generate an extensive and intense wind field,” Rayno explained.

Such explosive development would expand the impact zone and increase the strength of wind gusts across multiple regions.

Pacific and Gulf Moisture Will Fuel the Storm

The system will initially draw a significant amount of moisture from the Pacific Ocean.

Later, it will absorb additional moisture from the Gulf of Mexico and the Atlantic Ocean as it moves northeast.

Meteorologist Matt Benz said this combination will strengthen heavy rainfall and thunderstorms across several areas.

The interaction between warm and cold air masses is expected to increase atmospheric instability.

Blizzards and Extreme Cold in the North

In the Upper Midwest and the Great Lakes region, forecasters expect blizzard conditions.

The combination of heavy snow and strong wind gusts could create near-zero visibility on roads.

“Travel is likely to be especially dangerous on Monday,” Rayno warned.

Temperatures may not rise above 10°F in large areas of the northern United States.

Significant Snowfall Accumulations

A wide band of snow is forecast from parts of the North Dakota and South Dakota to northern Michigan.

Severe winter conditions could occur in areas of Wisconsin, Iowa and Northern Illinois.

Between Minneapolis, Green Bay, and the Upper Peninsula of Michigan, snowfall totals could reach 30 to 90 centimeters (12 to 35 inches).

In areas near Chicago and southern Michigan, rain could change to snow as the cold front advances.

Thunderstorms and Heavy Rain in the South and East

While the northern regions face snow and extreme winds, the southern United States will likely experience intense thunderstorms.

Torrential rainfall could affect areas from the Mississippi River Valley to the Atlantic coast.

Ahead of the cold front, southerly winds will push unusually warm temperatures northward, creating a sharp temperature contrast.

This contrast will help trigger showers, thunderstorms, and unstable weather conditions.

Flight Delays in the United States and Impact on Transportation and Power

Major airports across the country could face thousands of delays and cancellations between Sunday and Monday. Key aviation hubs expected to be affected include Denver, Chicago, Atlanta and New York City.

According to AccuWeather, power outages could impact hundreds of thousands or even millions of people. In some parts of the Midwest, officials are already considering school closures due to the threat of extreme conditions.

The storm follows a previous weather system and several recent cold waves. Authorities are urging residents to monitor forecasts and prepare for potential widespread disruptions as the 2026 U.S. megastorm approaches.

Meanwhile, the Southwest United States is expected to continue experiencing record-breaking temperatures despite the winter storm affecting other regions.
