In 2019, Storm Dorian destroyed the Abacos and Grand Bahama before skirting up the eastern seaboard making landfall on the eastern tip of Canada. Please see our “Bahamas after Dorian” page for current status of chartering and sailing in the Bahamas.
How did Dorian form?
Dorian was formed on the 24th of August by a tropical wave. A tropical wave is a low pressure, orientated from North to South which moves eastwards. This then combined with the high air pressure which lies in the doldrums or Intertropical Convergence Zone (ITCZ), located close to the termal equator.
Tropical waves explained
Tropical waves in the Atlantic develop from disruptions, which develop as far east as Sudan. They then drift across the continent into the Atlantic. These waves are either formed or enhanced by African Easterly Jet (The African easterly jet is a region of the lowest layer of the earth atmosphere, over West Africa where the seasonal mean wind speed is at a maximum and the wind is easterly).
The clockwise circulation of the large transoceanic high-pressure cell or anticyclone centered near the Azores islands, labeled the Azores high above image produces easterly waves away from the coastal areas of Africa towards North America.
When was Dorian at her peak intensity?
Dorian intensified while moving toward the Abacos and close by islands, before becoming a hurricane on August 28th. The rapid intensification of Dorian meant that on August 31st, she was placed into Category 4 – a major hurricane. Less than 24 hours later, Dorian reached Category 5 intensity, peaking with winds of 185 mph and gusts of much more. A minimum central pressure of 910 millibars, the ‘normal’ atmosphere is 1013.13 mbar a huge decrease of pressure meant that she would become to be one of the most devastating hurricanes to hit the Bahamas.
Why was Dorian moving so slowly?
This question is not to be confused with her wind and gust level. This is in relation to her track. Dorian stalled over the Bahamas for roughly 24 hours, 24 hours of heavy rain and gusts which lead to a 24ft storm surge.
Data has shown that she was traveling as little as 1 mph. This is due to a rare natural phenomenon called the Bermuda high. As the name states, this is a high-pressure atmospheric system. Until the Bermuda high relinquished its ‘hold’ over Dorian, a low-pressure system moved across releasing Dorian, thus allowing her to move in a northerly direction
