Temps in teens threaten citrus crops

(CNN) - Knee-knocking cold plagued the Deep South early Monday, threatening Florida citrus crops and sending much of the Southeast into the teens.

State capital Tallahassee had plunged to 16 degrees by 5:25 a.m. ET, while temperatures in the 30s or below could be found well south of Orlando.

The cold made Florida cities like Winter Haven anything but.

The National Weather Service issued a hard freeze warning that extended as far south as Lake Okeechobee.

Normally immune to the cold of winter, temperatures in Miami barely got into the 40s on Sunday; normally, they'd be in the 70s.

But the biggest news about the big chill is coming from the northern part of Florida, where a hard freeze watch is in effect, CNN's meteorologist Bonnie Schneider said. That could be bad news for citrus trees that rarely survive when temperatures remain in the mid-20s or below for four hours or longer, according to Kristen Gunter, a spokeswoman for the association of companies that pick and process the oranges.

Some groves in the northern part of the growing area had already sustained substantial damage Saturday night and Sunday morning, when temperatures dipped to 28 degrees or lower for at least six hours, said Andrew Meadows, spokesman for Florida Citrus Mutual, a group representing about 8,000 citrus growers in the state. It will take about five weeks to quantify the losses, he said.

Florida citrus is a $9.3 billion industry. The state produces three-quarters of the United States' orange crop and 40 percent of the world's orange juice supply.

"[Sunday night] will be the night to watch, because if things don't go well, the entire economy will be affected, jobs could be lost if fruit on the ground cannot be harvested, workers will go elsewhere in the U.S., and Florida will lose," Gunter said.

The citrus harvest is at its peak right now, she said, and workers are already grinding away seven days a week as it is. "I'm not sure we can work any faster," Gunter said.

Cold, of course, is relative. In Aberdeen, South Dakota, the thermometer registered a low of 31 below zero Sunday. Connecticut officials opened shelters in anticipation of bitter cold. Following a rare snowfall last week in Atlanta, Georgia, temperatures hovered in the teens and drivers lacking snow savvy skidded around very small patches of ice.

University of Florida wildlife biologist Dr. Frank Mazzotti was also working feverishly on Sunday. As part of an ongoing project, he and other scientists are working to euthanize iguanas, a non-native species that can disrupt the ecosystem. Cold weather makes his job easier: When temperatures drop, the iguanas, many up to 6 feet long, go into a stunned, catatonic state, stiffen and fall to the ground from tree branches and other perches.

The freeze is also going to be a test for the area's most unwelcome beast -- the Burmese python. The snakes have no natural predators and have been threatening the Everglades, the general ecosystem and even people since they were introduced to Florida through the illegal exotic animal trade, Mazzotti said.

The problem was graphically driven home in October 2005 in Everglades National Park, when wildlife researchers photographed a dead, headless python.

It had apparently exploded while trying to swallow a 6-foot-long alligator.

Lighter nibbles for pythons include native birds and other crucial members of the ecosystem.

"If pythons survive this cold, then that's going to tell us what a challenge it will be to get rid of them," Mazzotti said, adding that his team inserted transmitters on 10 of the snakes and will be monitoring them tonight.

More popular creatures at the Miami Metrozoo huddled under extra blankets. Ron Magill, zoo spokesman, said staffers removed chimps, gorillas and other primates from their cages Saturday and placed them in little beds with blankets.

The cold had customers of Florida Power & Light using electricity at a record rate to heat their homes and businesses. Customers were drawing more than 23,500 megawatts of power Sunday morning, breaking the old record of 22,300 megawatt hours set in August 2005, the utility said.
