Debby’s Slow March Through Gulf Drenches Florida

Tropical Storm Debby whipped Florida with bands of drenching rain Monday while its center was nearly stationary in the Gulf of Mexico. Its slow progress meant the most pressing threat from the storm was flooding, not wind.

Tropical storm warnings were in effect for parts of Florida as the storm parked offshore. A tropical storm warning for the coast of Alabama was discontinued early Monday. Yet even with the storm’s center far from land, it lashed Florida with heavy rains and spawned isolated tornadoes that killed at least one person. Another person was missing in rough surf off Alabama.

Residents in several counties near the crook of Florida’s elbow were urged to leave low-lying neighborhoods because of the threat of flooding. High winds forced the closure of an interstate bridge that spans Tampa Bay and links St. Petersburg with areas to the southeast. In several locations, homes and businesses were damaged by high winds authorities believe were from tornadoes.

Authorities in the Tampa Bay area were asking residents and tourists to stay away from flooded streets. Some streets were still under water early Monday, while others were blocked with debris.

“Gulf coast residents and visitors should take Tropical Storm Debby seriously,” said FEMA Administrator Craig Fugate. “Tropical Storm Allison in 2001 illustrates the immense amount of rain a slow-moving tropical system can produce. Flooding with Tropical Storm Debby is a very big concern for the Florida panhandle and portions of the southeast.”

Debby’s center was essentially stationary about 90 miles (145 kilometers) south-southwest of Apalachicola, Fla., early Monday. Debby’s top sustained winds decreased to near 50 mph (85 kph). The forecast map indicated the storm could inch forward through the week, eventually coming ashore over the Panhandle. However, a storm’s path is difficult to discern days in advance.

Underscoring the unpredictable nature of tropical storms, forecasters discontinued a tropical storm warning Sunday afternoon for Louisiana after forecast models indicated Debby wasn’t likely to turn west. At one point, forecasters expected the storm to come ashore in that state.

“There are always going to be errors in making predictions. There is never going to be a perfect forecast,” said Chris Landsea, a meteorologist at the National Hurricane Center.

A major concern will be flooding from heavy rainfall. The storm is moving slowly, allowing its clouds more time to unload rain. A public advisory said parts of northern Florida could get 10 to 15 inches of rain, with some areas getting as much as 25 inches.

The Highlands County Sheriff’s Office said in a news release that several tornadoes moved through the area southeast of Tampa, damaging homes.

Sheriff’s Office spokeswoman Nell Hays said a woman was found dead in a house in Venus that was destroyed in the storm. A child found in the same house was taken to the hospital. No further information was available on the child’s condition or either person’s age.

Authorities urged residents to leave low-lying neighborhoods in Franklin, Taylor and Wakulla counties because of flooding. Shelters were open in the area.

Wind tore the roof off a marina in St. Pete Beach, and a pier was heavily damaged, said Tom Iovino, a Pinellas County government spokesman. He said no injuries were reported.

In Orange Beach, Ala., a 32-year-old man disappeared Sunday in rough surf kicked up by the storm, said Coast Guard Lt. j.g. Torry James. Further information wasn’t immediately available.

As of Sunday, 23 percent of oil and gas production in the region had been suspended, according to a government hurricane response team. Employees have been evacuated from 13 drilling rigs and 61 production platforms in the Gulf of Mexico.

The storm was not expected to result in higher oil and gas prices.

“It’s largely a non-event for oil,” said Tom Kloza, chief oil analyst at the Oil Price Information Service.

The Federal Emergency Management Agency (FEMA) and its federal partners said they continue to monitor and work closely with states potentially affected by Tropical Storm Debby, including Florida, Georgia, Mississippi, Alabama and South Carolina.
