Which 1980 Atlantic hurricane reached Category 5 strength on three separate occasions?

Hurricane Allen was the 1980 Atlantic hurricane that reached Category 5 strength on three separate occasions.

Allen formed on August 1, 1980, from a tropical wave moving westward across the Atlantic. It strengthened unusually rapidly and crossed the Caribbean Sea, passing near the northern Caribbean islands before reaching the Gulf of Mexico. Favorable ocean temperatures and atmospheric conditions repeatedly allowed it to regain extreme intensity after weakening.

Allen ultimately reached maximum sustained winds of 190 mph and a minimum pressure of 899 millibars. At the time, those winds were the highest reliably recorded in the Atlantic basin. Its three Category 5 episodes are the key identifying fact; the storm was not continuously Category 5 for its entire journey.

The hurricane caused severe damage in Haiti, Jamaica, the Cayman Islands, Mexico, and South Texas, killing at least 281 people. Its name was retired after the season and replaced with Andrew, a name later used for another catastrophic Atlantic hurricane.
