Re: Another Pre-Season Storm?

Quote:

Most of the models I'm looking at bring it off the coastal carolinas, then retrograde it into the Fl/Ga area as a very weak system. Maybe Ed or Daniel can answer this, When a system retrogrades, one would think it would naturally get weaker due to the cooler water caused by it's own CDO. Is this normally the case with early season storms? Or I might just be over thinking things, it is still the Preseason.




A CDO (Central Dense Overcast) in and of itself is not at all enough to cool the waters along the path of a tropical cyclone. What is really required to cool SSTs in your hypothetical, is a vigorous cyclone either moving slowly, or looping about over the same general area, such that the cool waters from below begin upwelling to the surface enough to cool down the SSTs.
