Tropical depression floods N. Fla., S. Ga. JACKSONVILLE, Fla., June 27 (UPI) -- A tropical depression lashed northern Florida and southern Georgia with torrential rainfall, causing flash flooding, as it moved east Wednesday. The storm -- known as Tropical Storm Debby when its maximum sustained surface winds were 39 mph and greater -- had maximum sustained winds of 35 mph with higher gusts Wednesday morning, as it flooded homes and business districts and closed multiple roads. At 5 a.m. EDT, it was about 25 miles southeast of St. Augustine, moving east-northeast at about 10 mph and was forecast to be over the Atlantic Ocean Wednesday afternoon, the National Hurricane Center in Miami said. Four to 8 inches of rain was expected to fall, with isolated rain totals topping 25 inches, throughout some northern Florida areas, particularly north of Interstate 10, a major interstate highway that crosses the northern part of the state to Jacksonville, which received more than a foot of rain. Jacksonville's flash flooding led to numerous water rescues and reports of water entering homes Tuesday evening, the Weather Channel reported. Many coastal areas reported storm-surge flooding and gusty winds. One to 2 feet of rain flooded parts of northern and central Florida as Debby drenched much of the state for four straight days. Wakulla County -- a mostly rural Florida Panhandle area on the Gulf of Mexico, 30 miles south of Tallahassee -- reported more than 26 inches of rain Tuesday, after Debby sat nearly motionless offshore for four days. County officials rescued residents by boat and helped people evacuate livestock trapped by the rising waters. Live Oak, 80 miles east of Tallahassee, had waist-deep water, the Weather Channel said. Live Oak is surrounded on three sides by the Suwannee River, made famous by 19th century songwriter Stephen Foster. The storm spawned nearly two dozen tornadoes, which downed power lines, damaged homes and businesses and flipped tractor-trailer trucks. A 32-year-old mother of three was killed Sunday in a tornado in Venus, 80 miles east of Sarasota Springs. Heather Town was found about 200 feet from her home clutching her 3-year-old daughter, who survived, the Highlands County Sheriff's office reported. The woman's two other daughters were not home when the tornado struck. Debby was the earliest-ever fourth-named Atlantic storm, beating Hurricane Dennis, named July 5, 2005. In an average year, the fourth-named storm occurs by Aug. 23, the Weather Channel said.
