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

The Tampa-St. Petersburg area in Florida saw snow flurries and temperatures in the 20s in the Panhandle and 30s in South Florida on Sunday morning, Mullinax said. That left cold-stunned iguanas lying prostrate and motionless on the ground. Iguanas in South Florida go dormant in the cold and though they usually wake when temperatures warm, the reptiles can die after more than a day of extreme cold.

The cold also left ice on strawberries and oranges in the state. Farmers in Florida sometimes spray water on fruit trees and berry plants to protect them from the cold.

Meanwhile, the bomb cyclone, known to meteorologists as an intense, rapidly strengthening weather system, contributed to nearly a foot (30 centimeters) of snow in and around Charlotte, North Carolina's largest city. The snowfall represented a top-five snow event all time there, Mullinax said.

Flight cancellations exceeded 2,800 in the U.S. on Saturday, with another 1,500 on Sunday, according to FlightAware, a flight tracking and data company. About 800 of those Sunday cancellations were for flights departing or arriving Charlotte Douglas International Airport.

The storm caused an hours-long mess on Interstate 85 northeast of the city, after a crash left dozens of semitractors and other vehicles backed up into the evening, according to the State Highway Patrol. More than 1,000 traffic collisions and two road deaths were reported, North Carolina Gov. Josh Stein said Sunday.

“It’s an impressive cold shot, for sure, and there are daily records that are being seen down in the South," Mullinax said.

Snow blanketed the neighborhood of Lee Harrison, an insurance agent in a town outside of Greenville, North Carolina, and he planned to take his three daughters sledding in the backyard.

“We’re not gonna drive anywhere,” Harrison said. “It’s thick enough that I would not feel comfortable driving with our family.”

More than 110 deaths connected to the wintry weather and storms have been reported around the U.S. since late January. In Tennessee and Mississippi, two states struck last weekend by a storm carrying snow and ice, more than 97,000 customers were still without electricity on Sunday, according to the outage tracking website poweroutage.us. Another 29,000 didn't have power on Sunday in Florida.

Nashville Electric Service said it expects 90% of its customers to have power restored Tuesday, with 99% getting electricity back by next Sunday, two weeks after the ice and snow storm hit.

Gov. Bill Lee said he shared “strong concerns” with leadership of the utility, which has defended its response and said the storm was unprecedented.

Mississippi officials said it was the state’s worst winter storm since 1994. About 80 warming centers were opened and National Guard troops delivered supplies by truck and helicopter.

Mullinax said parts of the Carolinas are going to be “digging out” for several days as they contend with gusty winds and bitterly cold wind chills. Heading into Tuesday and Wednesday, light snow could fall in the Ohio Valley and the mid-Atlantic, from Washington D.C. and possibly into New York City, he said.
