Latest recon in the last few minutes supports 70mph in the northeast part of the system. This is an odd hybrid subtropical storm and very dry, relative to others. I can't really recall anything like it I've seen recently.

Is there such a thing as a "dry" hurricane??

Almost what it looks like...

Recon's found a little lower pressure with 991mb, and the storm actually moved a bit southwest (doing a cyclonic loop?) 28.2N 85.85W

Not sure if flight-level winds are efficiently mixing down to the surface, except in what could be more or less microbursts due to dry air, in which case I would expect surface winds in the mean to be running closer to 40-50, but gusting much higher (70, perhaps even higher). Alberto sure looks like what we typically see of a tropical cyclone undergoing extratropical transition, more so than the other way around. But I think a compelling case could be made to start calling him more tropical, than not.

Very latest pass through now showing a SW jog, and further lowering of central pressure.

Agreed that this is an odd one. Just a little breeze and mostly dry near Legoland.

I'm starting to think that the beginning of and end of seasons are going to becoming the frontiers of hurricane research.
