TALLAHASSEE, Fla. – Weather warnings forced some school districts in Florida’s northern counties to close just as students were set to return after a winter break. A massive front is bringing some of the coldest temperatures in years to parts of Florida. In central Florida, the state’s largest theme parks announced that water attractions such as Disney’s Typhoon Lagoon, Universal Orlando’s Volcano Bay and SeaWorld’s Aquatica were closed Wednesday because of the cold snap. The mayor of Jacksonville closed city offices to all but essential personnel on Wednesday, advising people to stay off the roads. In Tallahassee, school officials announced that classes would remain closed Wednesday. Copyright 2018 The Associated Press. All rights reserved.
