<snip>
Although slower forward movement was anticipated,[5] Allen kept at generally the same westward pace between 17 and 23 mph (27 and 37 km/h).[2] By August 3, the National Hurricane Center retracted predictions of less favorable conditions from the cold-low north of Puerto Rico, since that weather system was weakening and moving westward.[6]
By August 5, Allen intensified into a Category 5 hurricane during while south of Puerto Rico. This made Allen the earliest Category 5 hurricane in the Atlantic on record,[2] but was later surpassed by Hurricane Emily which reached that intensity on July 16, 2005. During this time, Allen attained a central pressure of 911 mbar (911 hPa; 26.9 inHg), the lowest pressure on record in the eastern Caribbean sea. Hence, the barometric pressure dropped by 35 mbar (35 hPa; 1.0 inHg) less than 10 hours after the National Hurricane Center stated that the pressure would not decrease significantly within 24 hours.
The eye passed between Hispaniola and Jamaica as a Category 4 hurricane. After weakening due to friction with the mountains of Haiti and Jamaica, Allen intensified back to a Category 5 hurricane, retaining this intensity for over a day. The storm moved between Cuba and the Yucatán Peninsula, reaching its minimum pressure of 899 mbar (899 hPa; 26.5 inHg) while crossing the Yucatán Channel. During Allen's trek through the Caribbean Sea and the Gulf of Mexico, its center of circulation never crossed over land despite its close passage to various islands in and around the Caribbean sea.[1]
Allen again weakened to a Category 4 storm due to friction with Mexico, but restrengthened into a Category 5 hurricane for a third time as it moved over the open waters of the Gulf of Mexico, keeping this intensity for nearly a full day and with a pressure drop to 909 mbar (909 hPa; 26.8 inHg), the lowest pressure ever recorded in the western Gulf of Mexico. Shortly before landfall, a dry air mass in the western Gulf of Mexico caused the storm to weaken substantially. Allen made landfall north of Brownsville, Texas as a Category 3 storm with maximum sustained winds of 115 mph (185 km/h). Allen became extratropical on August 11.[1]

That one came off the African coast on July 30 and formed on July 31. We still remember our luck with that one.
Dorian is weakening and moving West - just like Allen.
He may disappear but he may strengthen again although I think Florida will not be in his sights if he survives.
