St Lucia is divided into two zones: North & South. The North Zone includes Gros Islet, Castries, Anse la Raye, Canaries and Dennery and the South Zone includes Soufriere, Choiseul, Laborie, Micoud and Vieux Fort.

Payout is based on the weather index (excess rainfall and high wind speed) measured and reported in the two zones.
Each Zone has pre-defined thresholds, called trigger values, corresponding to different trigger levels and amount of payout (see tables below).

Once a trigger value is reached, the payout will be "triggered" automatically and be transferred to the client's bank account.
