<span-size:10.5pt;font-family:"Courier New";color:black">500 AM AST Thu Sep 13 2018

<span-size:10.5pt;font-family:"Courier New";color:black"> 

<span-size:10.5pt;font-family:"Courier New";color:black">Data from a NOAA P-3 Hurricane Hunter aircraft that departed the

<span-size:10.5pt;font-family:"Courier New";color:black">storm shortly before 0600 UTC indicated that the tropical storm has

<span-size:10.5pt;font-family:"Courier New";color:black">weakened a little more.  Maximum flight-level winds were around 51

<span-size:10.5pt;font-family:"Courier New";color:black">kt, while maximum SFMR winds were only 41 kt.  Both of these

<span-size:10.5pt;font-family:"Courier New";color:black">support an initial intensity of 40 kt.  Wind measurements from the

<span-size:10.5pt;font-family:"Courier New";color:black">plane also suggested that Isaac is close to opening up into a

<span-size:10.5pt;font-family:"Courier New";color:black">tropical wave and its circulation is likely barely closed at the

<span-size:10.5pt;font-family:"Courier New";color:black">surface.  Another P-3 mission is scheduled for this morning.

<span-size:10.5pt;font-family:"Courier New";color:black"> 

<span-size:10.5pt;font-family:"Courier New";color:black">Isaac is nearly completely devoid of deep convection at the moment,

<span-size:10.5pt;font-family:"Courier New";color:black">and is not trackable in radar data from Guadeloupe and Martinique.

<span-size:10.5pt;font-family:"Courier New";color:black">Given the lack of deep convection to sustain the cyclone, continued

<span-size:10.5pt;font-family:"Courier New";color:black">gradual weakening is expected.  However, given the extent of

<span-size:10.5pt;font-family:"Courier New";color:black">40 mph winds observed by the NOAA plane, Isaac is still likely to

<span-size:10.5pt;font-family:"Courier New";color:black">bring gusty conditions to many of the Leeward Islands through

<span-size:10.5pt;font-family:"Courier New";color:black">this afternoon.  The dynamical guidance is now in fairly good

<span-size:10.5pt;font-family:"Courier New";color:black">agreement on the intensity of Isaac for the next few days, and

<span-size:10.5pt;font-family:"Courier New";color:black">nearly all of the models depict Isaac opening into a trough between

<span-size:10.5pt;font-family:"Courier New";color:black">48 and 96 h.  The NHC forecast conservatively maintains Isaac

<span-size:10.5pt;font-family:"Courier New";color:black">through day 4 in an attempt to maintain some continuity, but it

<span-size:10.5pt;font-family:"Courier New";color:black">is very possible that Isaac will open into a trough sooner than

<span-size:10.5pt;font-family:"Courier New";color:black">indicated.  Some of the dynamical models suggest that regeneration

<span-size:10.5pt;font-family:"Courier New";color:black">could occur in the western Caribbean, however the predictability of

<span-size:10.5pt;font-family:"Courier New";color:black">such an event is too low to explicitly show in the forecast at this

<span-size:10.5pt;font-family:"Courier New";color:black">point.

<span-size:10.5pt;font-family:"Courier New";color:black"> 

<span-size:10.5pt;font-family:"Courier New";color:black">Isaac is still moving quickly westward, with an initial motion of

<span-size:10.5pt;font-family:"Courier New";color:black">275/15 kt.  Confidence in the track forecast remains high, and the

<span-size:10.5pt;font-family:"Courier New";color:black">track guidance is tightly clustered through the forecast period.

<span-size:10.5pt;font-family:"Courier New";color:black">Very little change was made to the track forecast, which continues

<span-size:10.5pt;font-family:"Courier New";color:black">to closely follow the HCCA model.  As long as Isaac remains a

<span-size:10.5pt;font-family:"Courier New";color:black">shallow cyclone, it should continue to be steered westward by the

<span-size:10.5pt;font-family:"Courier New";color:black">low-level tradewind flow, even if, or when, it opens up into a

<span-size:10.5pt;font-family:"Courier New";color:black">trough.
