DISCUSSION: In light of the recent passing of tropical cyclone Fantala, there has been a lot of initial work done with respect to studying the evolution and behavior of this intense tropical cyclone which rapidly strengthened off the coast of Madagascar (relatively close to the Eastern Africa). Here is a fascinating view of this historic tropical cyclone by way of a satellite-derived 72-hour precipitation accumulation graphic! Note the incredibly intense rainfall associated with this particular tropical cyclone! Fortunately, it's land-based impacts were fairly minimal overall.

DISCUSSION: Over the past few days, a weak tropical low-pressure moving in a southwesterly direction across the Western Indian Ocean has rapidly strengthened into the most powerful tropical cyclone on-record across the Indian Ocean basin. At its peak intensity, Tropical Cyclone Fantala had maximum sustained winds of 173 MPH with higher gusts! Note the eyewall replacement cycles which occurred during the course of Fantala's period of maximum intensity. This is relatively common with tropical cyclones near the time of maximum intensity as various ambient atmospheric parameters induce slight fluctuations in storm intensity and satellite imagery appearance due to the expansion or contraction of the central dense overcast (the cirrus cloud shield which results from intense thunderstorms which wrap around the center of the tropical cyclone) as well as the aforementioned eyewall replacement cycles which often take place near the time of maximum intensity.
