Tropical Storm Hermine picked up strength and was expected to be a hurricane when it reaches Florida’s north Gulf Coast, bringing heavy rains and high winds that forecasters warned could cause catastrophic flooding.
With as much as 20” (51cm) of rain expected, schools in several Florida coastal counties were closed yesterday and some low-lying areas already have seen floods from Hermine.
After battering the coast, the storm is expected to move across the northern part of the state and then barrel toward southern US coastal regions on the Atlantic.
“Take this storm seriously,” said Bryan Koon, director of the Florida Division of Emergency Management.
Governor Rick Scott has declared a state of emergency to free up state resources to battle the storm, with 49 of Florida’s 67 counties covered by the declaration.
As of 8am EDT (1200 GMT), the storm was about 195 miles off the Florida coast and packing maximum sustained winds of 65mph (100kph).
In addition to heavy rains, it was expected to cause isolated tornadoes and bring storm surges of up to 6’ (1.8m), the National Hurricane Centre in Miami said.
“There is a danger of life-threatening inundation within the next 36 hours along the Gulf coast of Florida,” it said.
Large parts of Florida’s panhandle coast were under a hurricane warning, while flash flood watches stretched from Florida into South Carolina.
On its current path, the storm also could dump as much as 10” (25cm) of rain on coastal areas of Georgia, which was under a tropical storm watch, and the Carolinas.
Yesterday Georgia Governor Nathan Deal signed an executive order declaring a state of emergency for 56 counties that extends through midnight tomorrow.
A tropical storm warning also was issued for the US East Coast from Marineland, Florida, to South Santee River, South Carolina, the National Hurricane Centre said.
US oil and gas producers removed workers from 10 offshore platforms in the eastern part of the Gulf of Mexico, moved drilling rigs and shut some output because of the storm.
As of yesterday morning, the storm had not caused any major disruption to US air travel, according to tracking service FlightAware.com.
The hurricane centre also said in an advisory that another storm, Hurricane Gaston, will move near the Azores today.
In the Pacific, Hurricane Madeline weakened to a tropical storm as it passed south of Hawaii’s Big Island, where officials had opened shelters and shuttered offices and schools on Wednesday.
Before the tropical storm moves westward out of reach of Hawaii, it is expected to dump as much as 15” (40cm) of rain on parts of the Big Island, the National Weather Service said.
Hurricane Lester, currently a major Category 4 storm, could affect Hawaii during the weekend.
Hawaii Governor David Ige has already signed an emergency proclamation freeing up state resources which runs through September 9.
Hurricane specialist Eric Blake works at the National Hurricane Centre to track the path of Tropical Storm Hermine, which strengthened yesterday and is expected to make landfall along Florida’s Gulf Coast.
