The fictional hurricane is named Irma. In September 2017 filming was stopped owing to a real hurricane Irma passing near to Guadeloupe.
The real Hurricane Irma that struck the Caribbean and US in 2017 was so destructive and caused so much loss of life that the name was retired by the World Meteorological Organization in 2018.
The title is sometimes given as "A Stormy Occurrence"
Alternate title "Hurricane on Saint-Marie"
