The effects of a severe winter storm that brought blizzards and below-freezing temperatures to much of the US are still being felt.
On the second day of the storm, there are now more than 800,000 customers without electricity across five states, including 680,000 in Michigan.
According to data from FlightAware, more than 700 US flights have been canceled as of Thursday morning.
Other US regions prepare for temperature records in the meantime.
On Thursday, Washington, DC, is predicted to experience 80°F (26°C), the warmest February day since 1874.
Texas' McAllen recorded a scorching 95F on Wednesday. High temperatures in Nashville, Tennessee, and Lexington, Kentucky, also broke records that had been in place for more than a century.
However, severe winter weather is affecting other parts of the US.
Blizzards in the northern states have caused businesses, state legislatures, and even schools to close. Tim Walz, the governor of Minnesota, requested the National Guard's assistance for drivers stuck on the icy roads.
According to the New York Times, a volunteer firefighter in Michigan died as a result of the storm. Although the cause of death was not disclosed, local news sources claimed that a downed powerline was to blame.
Millions of people were warned to prepare for unusually cold temperatures, scalding winds, and snow in southern California, which is known for its year-round warmth and sunshine.
Local media reported that high winds in some parts of the US caused a large redwood tree to be uprooted and "spear" into the living room of a house in the Bay Area of California. A one-year-old child was there, according to fire officials, in critical condition.
According to the Bay Area fire department, the wind had caused a flood of calls about downed trees, trees blocking homes, and power lines clogging roads.
After portions of southern Ontario were covered in snow during Wednesday's evening rush hour, ice pellets and freezing rain were predicted for Canada overnight.
