Storm Floaters | Atlantic Imagery
|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.||
Subjective position estimates of tropical disturbances and cyclones across the globe using a variety of microwave sensors.
|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 24 hours in 1 by 1 degree latitude/longitude areas from 45S to 45N and 0 to 360E.|
