Junior Cycle Geography CYCLONE Case Study: Hurricane Dorian 2019


Hurricane Dorian is the most powerful Category 5 Hurricane to hit the Bahamas since records began. On 23 August 2019, a low-pressure system formed in the Atlantic Ocean. By 24 August, it had become a tropical storm. Four days later, it was classified as a hurricane as it had reached wind speeds of 350 km/hr and higher.


The islands of Abaco and Grand Bahama were the worst affected. At least 65 people were confirmed to have died on just these two islands, with many more missing. It was estimated that 13,000 homes were severely damaged or destroyed.
