Last season we had two severe tropical storms (Noel in October; Olga in December) and one hurricane (Dean in August) which ended up only causing minor damage.
Storms and hurricanes rarely affect tourist areas and when they do the disruption tends to be limited to heavy rain keeping people indoors, and the effects only last a few days.
The main victims are people in poor-quality dwellings who live in vulnerable areas - riverbanks and flood plains - worlds away from the tourist sector.
