Initial reports from the Bahamas suggest that the islands of Great Abaco and Grand Bahama have been left devastated from Major Hurricane Dorian, evoking memories of the destruction on the eastern Caribbean island of Barbuda in the immediate aftermath of Hurricane Irma just two years ago.
A Record-Breaking Hurricane for the Bahamas and the Atlantic
Dorian underwent an unprecedented period of rapid intensification between August 31 and September 1, that took its maximum sustained wind speed from 150 miles per hour to 185 miles per hour. No other Atlantic hurricane on record has intensified as rapidly as this from such a high initial wind speed. Dorian joins an exclusive group of Atlantic hurricanes to attain wind speeds of 185 miles per hour or greater: Allen (1980), Wilma (2005), Gilbert (1988), and the Labor Day Hurricane (1935).
Dorian maintained this intensity on September 1, and then made a series of landfalls – first across Great Abaco island, and on September 2 across Grand Bahama. In doing so, Dorian became the strongest hurricane in modern records to strike the northwestern Bahamas. As the Category 5 hurricane traversed the islands, its forward speed slowed and it became near stationary over Grand Bahama for roughly 36 hours before gradually moving northwest. Dorian’s eyewall subjected some areas of these islands to destructive wind gusts of up to 220 miles per hour (354 kilometers per hour) and catastrophic storm surge in excess of 20 feet (6 meters).Continue reading
