Please select your preferred storm risk level for TSR to start issuing you with email warnings. Alert/risk levels are defined by colour and determined by the forecast wind strength at landfall and its chance of happening. Please select one option only:

Green Alert (Low)* Yellow Alert (Elevated)* Red Alert (Severe)
Tropical storm strength TS winds (39mph 1-min sustained) forecast to strike land to between 31% and 50% probability. TS winds forecast to strike land to above 50% probability, or CAT 1** or above winds forecast to strike land to between 10% and 30% probability. CAT 1** (74mph 1-min sustained) or above winds forecast to strike land to above 30% probability.
Selection of the 'green' or 'yellow' alert levels means you will also receive warnings for storms threatening landfall in the higher alert category(s).
CAT 1 includes hurricane, typhoon, tropical cyclone and severe cyclonic storm strength (74mph, 119 km/h or 64 knots 1-min sustained).

Please select how often you wish to receive email alerts (when a storm is triggering and there is a change in forecast wind probability from the previous alert):

Every 6 hours or after each advisory update Every 12 hours Once a day

You will receive email confirmation of successful registration.
