Hermine Strengthens Into A Hurricane As It Approaches Florida

A satellite image shows Tropical Storm Hermine forming in the Gulf of Mexico on Wednesday. The storm is expected to make landfall north of Tampa late Thursday night or early Friday morning, the National Hurricane Center says.

Hermine, in the Gulf of Mexico, is growing stronger as it approaches the Florida coast, and is now packing the force of a hurricane, the National Hurricane Center says.

Citing data from an Air Force Reserve Hurricane Hunter aircraft, the weather center says Hermine's maximum sustained winds increased to near 75 mph (120 km/h) Thursday afternoon — making it the fourth hurricane of 2016 in the Atlantic basin.

The storm, which has been moving very slowly, is forecast to make landfall north of Tampa, likely early Friday. It's then predicted to pass overland toward the coasts of Georgia, South Carolina and North Carolina, weakening as it goes.

It's been nearly 11 years since a hurricane made landfall in Florida: Since Hurricane Wilma hit the state in 2005, not a single hurricane has made landfall along the Florida coastline.

It also becomes the first hurricane to form in the Gulf Coast since 2013, ending the longest streak of hurricane-free days recorded in the last 130 years.

We should note that even storms that are not hurricanes can cause devastating damage. And a recent article in the Bulletin of the American Meteorological Society, addressing the frequency of major hurricanes making landfall in the U.S., called the definition of such a drought "largely arbitrary."

The National Hurricane Center warns of strong winds and a dangerous storm surge along Florida's Gulf Coast and says rain accumulation may cause flash flooding in any of the affected states.

There's also a risk of tornadoes, the center says.

Hermine is expected to strengthen into a hurricane before making landfall north of Tampa, likely early Friday.

Florida Gov. Rick Scott ordered all state offices in 51 counties to close at noon on Thursday, and Georgia Gov. Nathan Deal declared a state of emergency in 56 counties ahead of the storm.

Meanwhile, Hawaii has dodged a direct hit from one of two powerful storms in the Pacific, as Bill Dorman of Hawaii Public Radio reports for our Newscast unit:

"Tropical Storm Madeline did not make a direct hit on the Big Island of Hawaii. The center of the storm passed south of the island, but high winds and heavy rains did barrel ashore, sparking a flood advisory.

"Madeline was downgraded from a hurricane on Wednesday but remained strong enough to cause damage. About 3,600 customers lost electricity during the day; the Hawaii Electric Light Co. reported most had power restored by nightfall.

"Hurricane Lester remains farther off the coast of the island chain and has weakened — but still remains a potential threat for Labor Day weekend."
