Re: New Vortex...big pressure drop...

No..Arlene is not a hurricane as of this vortex message. The flight level winds are 75 kts; not the surface. They try an obtain a surface wind when they can; but most of the time it is extrapolated from winds at flight level; and depending on what FL is, depends on what percentage they lower it. Latest 11/0435Z message shows FL winds of 71 kts and they recorded a sfc wind of 57 kts; but 120NE of the center. I suspect if the center was under the convection they might have upgraded her to a CAT 1 storm; but she continues to be disjointed and convection tops have warmed considerably on past few satellite frames. What appears to be the low level center is well removed from it's upper level circulation.
