Our Emergency Operations Command will continue closely monitoring this storm and additional counties may be included in this declaration as needed."

Original story:

Florida may be about to get its first hurricane in more than a decade. Tropical Storm Hermine was hurtling toward the Gulf Coast Thursday morning, threatening cities like Tallahassee and Tampa as it strengthened in the Atlantic Ocean.

A National Hurricane Center update from 8 a.m. EDT put the storm system about 200 miles south-southwest of Apalachicola, Florida, moving north-northeast with maximum sustained winds of 65 mph. The eye was on track to reach the coast late Thursday.

"Additional strengthening is anticipated, and Hermine is expected to be a hurricane by the time landfall occurs," the center wrote. "Preparations to protect life and property should be rushed to completion."

The system was forecast to drop between 5-10 inches of rain in Florida and Georgia, with some areas getting up to 20 inches and experiencing flash flooding. Tornadoes were possible, as well. Hurricane and tropical storm warnings and watches were in effect for most of Florida's west coast Thursday.

If Hermine hits Florida as a hurricane, it'll be the first one since 2005's Hurricane Wilma, WFTV reported.

Gov. Rick Scott referenced that fact as he declared a state of emergency for 51 counties Wednesday. "Fortunately we haven't had a hurricane in a long time, so people often get complacent. So just think about this: Follow the news, have a battery powered radio in case you lose your power so you can follow," WCJB reported he said at a news conference.

School was canceled in Hillsborough County and at the University of South Florida on Thursday. The Busch Gardens theme park closed its doors, as well.

Weather Channel meteorologist Kevin Roth told NBC News that locals should get ready in case of evacuations. "Residents in Florida need to pay attention to the latest that Hermine is doing," he said. "It could be a very lousy holiday weekend for a large part of the population."
