| Extratropical |
A term used in advisories and tropical summaries to indicate that a cyclone has lost its "tropical" characteristics. The term implies both poleward displacement of the cyclone and the conversion of the cyclone's primary energy source from the release of latent heat of condensation to baroclinic (the temperature contrast between warm and cold air masses) processes. It is important to note that cyclones can become extratropical and still retain winds of hurricane or tropical storm force. |
Hurricane season in the Atlantic lasts from June 1st to November 30th.
Tropical storms are given male and female names because this makes them easier to track. Before 1979 though, they only had female names.

Hurricanes are grouped into 5 categories according to their strength. Category 5 hurricanes are the strongest.
The “eye” is the centre of the hurricane and is the calmest part.
