More winter weather leads to heavy snow, canceled flights and, in Florida, falling iguanas

A huge swath of the U.S. from the Gulf Coast into New England is mired in extra-cold temperatures after a bomb cyclone brought heavy snow. There were hundreds of flight cancellations to North Carolina, snow flurries and falling iguanas in Florida, and more misery for thousands who are still without power from last weekend’s ice storm in the South. About 150 million people are under cold weather advisories and extreme cold warnings in the eastern portion of the U.S. Wind chills have been near zero to single digits in the South, with Florida experiencing its coldest air mass since December 1989.
