Sample MTCSWA Graphic 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. Sample TCFP Graphic 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.
