When is cyclone season in American Samoa?
Cyclone season in American Samoa runs from 1 November to 30 April, according to the Fiji Meteorological Service.
A cyclone starts as a cluster of thunderstorms over warm ocean water. Warm, moist air rises from the sea surface. The air pressure near the surface drops, and more air flows in. The rotation of the Earth makes this air spin, clockwise in the Southern Hemisphere. Weak winds high in the atmosphere let the system organise. A system with a closed circulation is called a tropical depression. It becomes a tropical storm when its winds strengthen, and the Fiji Meteorological Service gives it a name. It becomes a cyclone when its winds reach cyclone strength.
Sea temperatures around American Samoa are highest in the southern summer. This is the time of the most storm activity. Cyclones often form over the warm water of the South Pacific Ocean, north and north-east of Fiji and Vanuatu. Cyclones usually reach American Samoa from the north or north-west, across the South Pacific Ocean. Pago Pago Harbor is a deep natural harbour on Tutuila.

What does the forecast cone show on the American Samoa map?

The cone does not show how far wind, rain, or storm surge reach from the centre, so areas outside the cone can still have storm effects. The cone is part of the Storm Tracks layer, together with the current position, the past path, and the forecast path.
