INTERNATIONAL: About 1,400 U.S. flights were canceled early on Sunday,January 30, after the northeastern part of the country was walloped by a fierce winter storm a day earlier.

Several U.S. states had declared emergencies in response to the storm, which formed in the Atlantic Ocean off the Carolinas and was forecast has continue depositing snow until Sunday morning as it moved north to Maine.

The total number of flight cancellations within, into, or out of the United States was about 1,400 as of 10:30 a.m., according to flight-tracking website FlightAware.com. Another 647 U.S.-related flights were delayed, the data showed.

The LaGuardia Airport and the John F. Kennedy International Airport in New York City and the Boston Logan International Airport each had over 200 flight cancellations as of early Sunday.

Falling Iguanas from Trees, Immobilised but not Dead

The National Weather Service Miami-South Florida has warned the public on Sunday,January 30, that immobilized iguanas could fall from trees due to cold temperatures across the region.

"Iguanas are cold-blooded. They slow down or become immobile when temps drop into the 40s. They may fall from trees, but they are not dead," the service said on their social media.

Zoologist Stacey Cohen, a reptile expert at Palm Beach Zoo in Florida, has explained the phenomenon to ABC affiliate WPBF.

Cohen says Iguanas’ bodies basically start to shut down where they lose their functions and so they are up in the trees on the branches sleeping and then because it gets so cold, they lose that ability to hang on and then they do fall out of trees a lot.

Although most of the reptiles will likely survive this period of immobilization, Cohen has also added freezing temperatures were a threat to their survival and pointed to a cold snap in 2010 that wiped out a large number of the population.

Cold is very life-threatening thing for the iguanas because they are from parts of Central and South America close to the equator where it always stays very warm.

According to the National Weather Service, temperatures in South Florida reached a low of 25 degrees Fahrenheit , that’s minus 4 Celsius on Sunday morning, and high temperatures on Sunday were expected to remain in the upper 50s to low 60s , about 10-15 Celsius.
