|The eTRaP is a simple ensemble that allows for the generation of probabilistic forecasts of rainfall in addition to deterministic rainfall totals.|
|Dvorak Classifications||Microwave Positions|
Subjective position and intensity estimates of tropical disturbances and cyclones across the globe using the internationally recognized Dvorak technique.
ATCF Info|ATCF Format Description
Subjective position estimates of tropical disturbances and cyclones across the globe using a variety of microwave sensors.
|Text bulletins disseminated by 0400Z, 1000Z, 1600Z, and 2200Z describing the position and intensity estimates for tropical disturbances and tropical cyclones in the Eastern and Southern Hemispheres.||MTCSWA combines information from several data sources to create a mid-level wind analysis which is then adjusted to the surface. Eight products are displayed, most notably an inner core scale surface wind analysis.|
|The Tropical Cyclone Formation Probability Product provides an estimate of the probability of tropical cyclone formation within the next 24to 48 hours in 1 by 1 degree latitude/longitude areas from 45S to 45N and 0 to 360E.||The ADT provides an automated, objectively-derived estimate of the tropical cyclone location and intensity using the latest official forecast bulletins from the Join Typhoon Warning Center (JTWC) and from Regional Specialized Meteorological Centers (RSMC), such as the National Hurricane Center (NHC) and the Central Pacific Hurricane Center (CPHC).|
