Wary Gulf Coast Closely Watching Debby's Movement Parts of three states were under a tropical storm warning Sunday as Debby churned off the Gulf Coast, leaving wary residents to closely watch a storm whose path has so far been difficult to forecast. Low-lying coastal areas in Louisiana were under a tropical storm warning, and the governor declared a state of emergency to free up resources ahead of a possible landfall. Warnings also were issued for coastal Alabama and parts of Florida, including the Panhandle. Debby already had dumped heavy rain on parts of Florida and spawned some isolated tornadoes, causing some damage to homes and knocking down power lines. It was not completely clear when or where Debby would make landfall, though current models showed it reaching hurricane strength by the time it hit the Louisiana coastline. The National Hurricane Center in Miami said Sunday morning that Debby was about 200 miles (325 km) east-southeast of the mouth of the Mississippi River. Debby's top sustained winds were at about 60 mph (95 kph). The storm was moving toward the northeast at 5 mph (7 kph). Another was reported Sunday in Venice, damaging some homes. However, despite warnings in the Panhandle, Debby hadn't totally dampened vacations. Thousands of people were on the beach at Pensacola Beach, Fla., on Sunday morning. Many used their phones to take photos of huge waves crashing into the concrete supports of a fishing pier. There wasn't any rain yet; just gusty winds and dark, fast-moving clouds. Few people were in the water. Red flags warned tourists to stay out of the surf, and lifeguards cruised the sand on all-terrain vehicles, blowing whistles at anyone who got near the waves. Workers with rental companies used pickup trucks to gather chairs and umbrellas as a precaution against an unusually high tide. Forecasters said Debby could reach hurricane strength sometime over the next few days. Meanwhile, up to 10 inches of rain were possible along the coast, with isolated amounts possibly reaching 15 inches.
