 HURRICANE NICOLE DISCUSSION NUMBER  35
 NWS NATIONAL HURRICANE CENTER MIAMI FL       AL152016
 500 PM AST WED OCT 12 2016
 
 Nicole has a very impressive satellite presentation this afternoon.
 The eye has warmed and become more distinct since this morning, and
 the convective cloud tops surrounding the eye have cooled. As a
 result, subjective Dvorak intensity estimates have increased to
 T5.5/102 kt from TAFB and SAB. Since earlier satellite estimates
 were slightly higher than the intensity supported by this morning's
 reconnaissance data, the initial intensity has been raised to 95 kt,
 which is slightly lower than current Dvorak estimates. Another Air
 Force Reserve Hurricane Hunter aircraft is scheduled to investigate
 Nicole this evening and should provide a better assessment of the
 hurricane's intensity.
 
 Low vertical wind shear and warm waters along the path of the
 hurricane through tonight could allow for some additional
 strengthening, and Nicole is forecast to reach major hurricane
 strength before it passes Bermuda. After that time, increasing
 southwesterly shear and cooler waters should cause some weakening.
 Strong westerly shear in a couple of days is expected to cause
 Nicole to become post-tropical, but baroclinic forcing is expected
 to keep the cyclone very strong through the entire forecast period.
 There is a large amount of uncertainty in the global models as to
 how much in the way of tropical characteristics Nicole will have
 late in the period, and the status of the cyclone is of low
 confidence at that time.
 
 Nicole is moving just east of due north or 010/9 kt. The hurricane
 will be moving into the mid-latitude southwesterly flow, which will
 cause Nicole to accelerate north-northeastward and then
 northeastward during the next 24 hours. This motion will bring the
 core of the hurricane near or over Bermuda on Thursday. In about 72
 hours a shortwave trough is forecast to bypass the cyclone, which
 should cause Nicole to slow down and meander over the North Atlantic
 at days 4 and 5.
