The major storm system in the United States that has been developing over recent days has turned into a multi-hazard and cross-country weather phenomenon.

The storm has already caused widespread, chaotic travel disruption and life-threatening risks in multiple states across the country.

Plowing through Central US, the large-scale storm continues to head towards the Eastern US-bringing multiple severe weather phenomena, including torrential rain, flooding, heavy snow, and strong winds.

Thousands of flights have been canceled and road traffic disruptions have been reported in major routes.

The US weather authorities have issued multiple severe weather warnings for flash floods, thunderstorms, and tornadoes in different areas.

So far, there were no immediate reports of casualties amid the storm, which is expected to continue at least in the coming hours or days.

US meteorologists are considering it as a record-breaking storm due to its effect in some areas across the US that have not been seen in decades, including the thick accumulation of snowfall and the current damage it has brought.

More than 1,000 domestic and international flights across the US have been canceled and over 4,000 flights have been delayed due to the raging storm, as per the FlightAware tracker website.

Based on the latest weather forecasts, further cancellations or delays are expected.

The most affected airports are the Chicago O'Hare International Airport (ORD) in Chicago, Illinois; and the Detroit Metropolitan Wayne County Airport (DTW) in Romulus, Michigan.

Due to the persisting storm, flight disruptions are likely to affect other airports across the US.
