According to flight tracking website FlightAware, a total of 1,243 flights in the US were canceled and 514 were delayed as of 7:14 a.m. local time.

United Airlines led the list of cancellations with 238 flights, followed by 215 by Southwest Airlines, Reuters reported.

"We expect some operational challenges due to weather in the Midwest today, and possibly tomorrow due to winter weather in the region," Delta Air Lines said.

The decision to delay and cancel some flights came after the Federal Aviation Administration warned that rain, snow and wind could delay operations at some airports.

Severe weather warnings have also been issued across the United States by the National Weather Service, according to CNN. The severe storms hitting the eastern part of the country are just part of the current active weather pattern.

Another powerful storm in the northwest is bringing snow and wind to the region. Weather experts warn that temperatures could change in some states as a severe cold front begins to move from Canada into the northern United States.

Even Hawaii is facing the impact of stormy weather as a cold front sweeps across the islands.
