 Jeanne formed from a tropical wave, becoming a tropical depression on September 13 near the Leeward Islands, and strengthening to a tropical storm the next day. Moving west-northwestward, Jeanne struck Puerto Rico on the 15th with 70 m.p.h. winds and then strengthened to a hurricane just before making landfall in the Dominican Republic. Jeanne spent nearly 36 hours over the rough terrain of Hispaniola, generating torrential rainfall before emerging into the Atlantic north of the island. Steering currents in the western Atlantic were weak, and Jeanne moved slowly through and north of the southeastern Bahamas over the next five days while it gradually regained the strength it had lost over Hispaniola. By the 23rd , high pressure had built in over the northeastern United States and western Atlantic, causing Jeanne to turn westward. Jeanne strengthened and became a major hurricane on the 25th while the center moved over Abaco and then Grand Bahama Island. Early on the 26th , the center of Jeanne’s 60-mile-wide eye crossed the Florida coast near Stuart, at virtually the identical spot that Frances had come ashore three weeks earlier. Maximum winds at the time of landfall are estimated to be near 120 m.p.h. Jeanne weakened as it moved across central Florida, becoming a tropical storm during the afternoon of the 26th near Tampa, and then weakening to a depression a day later over central Georgia. The depression was still accompanied by heavy rain when it moved over the Carolinas, Virginia, and the Delmarva Peninsula on the 28th and 29th before becoming extratropical. Jeanne produced extreme rain accumulations in Puerto Rico and Hispaniola, with nearly 24 inches reported in Vieques. Rains from the cyclone resulted in historic floods in Puerto Rico, and deadly flash-floods and mudslides in Haiti, where over 3000 people lost their lives and roughly 200,000 were left homeless. Three deaths occurred in Florida, and one each in Puerto Rico, South Carolina, and Virginia. In the United States, damage is estimated to be near $6.9 billion. |
A well-organized but slow moving tropical wave that exited the African coastline on September 1st developed into Tropical Storm Isabel on the morning of September 6th. Isabel became a hurricane on September 7th and rapidly intensified to Category 4 hurricane strength on the evening of the 8th while the eye was located more than 1100 miles to the east of the Leeward Islands. This impressive hurricane reached Category 5 strength on September 11th, making Isabel the strongest hurricane in the Atlantic basin since Mitch in October 1998. The cyclone turned northwestward around the western periphery of the Atlantic ridge beginning on the 15th. Isabel began to weaken on the 15th as conditions aloft became more hostile, and it fell below major hurricane strength for the first time in eight days on the 16th.  Although weakening, Isabel’s wind field continued to expand as hurricane warnings were issued for most of the North Carolina and Virginia coastline, including the Chesapeake Bay. Isabel’s large eye pushed ashore just after the noon hour on September 18th near Drum Inlet along North Carolina’s Outer Banks. Isabel was the worst hurricane to affect the Chesapeake Bay region since 1933. Storm surge values of more than 8 feet flooded rivers that flowed into the Bay across Virginia, Maryland, Delaware, and Washington, D.C. Isabel brought tropical storm force gusts as far north as New York State as it moved inland. The most intense hurricane of the 2003 season directly resulted in 17 deaths and more than 3 billion dollars* in damages. The large wind field toppled trees and cut power to more than four million customers. |
