Notes from ExtendWeather:

  1. The ExtendWeather forecast is based on the Global Forecast System (GFS) forecast.
  2. Uncertainty will always occur on cyclone tracks as depicted by GFS but is often close to the consensus of an ensemble of track models for tropical depressions in the region. For more details on all the tracking models we encourage you to visit
  3. The GFS forecast movie depicts a three hourly forecast based on hourly model outputs. Its value is not only in tracking but also in its depiction of the speed of a tropical depression or cyclone's forward movement. It is noted that the forward progress of tropical depressions and cyclones do fluctuate considerably and a slowing in forward speed can lead to more intense impacts by increasing local rainfall amounts and damaging winds.
  4. As expressed elsewhere risks posed by tropical depressions and cyclones can be serious and cover a considerable geographic area. Please heed local warnings and evacuation notices.
