 HURRICANE GASTON DISCUSSION NUMBER  40
 NWS NATIONAL HURRICANE CENTER MIAMI FL       AL072016
 1100 AM AST THU SEP 01 2016
 
 Despite a degraded satellite presentation, a 1302 UTC ASCAT-B pass
 over Gaston showed a large area of hurricane force winds southeast
 of the center and peak winds of 75 kt, and that will serve as the
 initial intensity for this advisory.  Weakening is forecast as
 Gaston moves across the 26C SST isotherm later today and the
 vertical shear is expected to increase to 20-30 kt by 48 hours.
 Gaston should fall below hurricane strength tonight and gradually
 lose tropical characteristics by 48 hours.  The low is forecast to
 dissipate by 72 hours, as shown in the global models.  The NHC
 intensity forecast is close to the new IVCN intensity consensus aid.
 
 The hurricane is moving quickly east-northeastward, 070/21.  Gaston
 will continue moving generally east-northeastward within the mid-
 latitude westerlies through dissipation.  The new NHC forecast is
 near the middle of the guidance envelope and the multi-model
 consensus TVCN.
 
 Based on the current forecast, the Azores Meteorological Service has
 issued a Tropical Storm Warning for the islands of Faial, Pico,
 Graciosa, Sao Jorge, and Terceira in the central Azores.
