It dont take much to call a storm subtropical...all it needs its 35kt winds at the surface close to the center (near the storms) and a warm core center. ... This does have a marginal warm core center but its in a shear enviroment. Water temps are in the low 80s. I dont think its fully tropical though..nonetheless if they find this a closed center(as it is) then they will issues tropical storm warnings at 5pm. Bouys well east and near Cuba have exceeded 52mph. Models still say that this hybrid type system will have winds near 50mph by morning..Affects on the land will only be 25-40mph near and east of the strengthening hybrid system. It should be extratropical or more baroclinic after it makes landfall in florida from Sarasota-Citrus County. Overall this will bring rainfall amounts around 2-4 inches over most locations east of the center...isolated amounts up to 6inches. To the north of the center..expect less then a inch as drier air will be pulled in from the west. Isolated tornados will accompany in isloted stronger cells over florida..especially on Saturday when the system approaces land.

bottom line..tropical or not...its strengthing and will all the way till it passes the carolinas...the winds will continue to pick up and expand up the coast from Florida-NC by Sunday.
