| #873170 (Received by flhurricane at: 10:38 AM 28.Aug.2016) TCDAT2 HURRICANE GASTON DISCUSSION NUMBER 24 NWS NATIONAL HURRICANE CENTER MIAMI FL AL072016 1100 AM AST SUN AUG 28 2016 The eye was fairly distinct a few hours ago, but recently it has become slightly cloud-filled and the inner-core convection has become less symmetrical. The current intensity is set at 90 kt, in agreement with a Dvorak estimate from TAFB and objective ADT values from UW-CIMSS. Assuming the slight degradation of the inner core structure to be temporary, a little more strengthening is expected within the next 12 to 24 hours. Gaston should remain in a low to moderate vertical wind shear environment for the next couple of days, which would allow the hurricane to more or less maintain its intensity through 36-48 hours. By 72 hours and beyond, increasing westerly shear should induce weakening. The official intensity forecast is close to the multi-model consensus IVCN. Steering currents are weak, and the initial motion is a northwestward drift or 320/4 kt. Gaston's motion is being partially blocked by a narrow subtropical ridge, and this scenario should continue for the next day or so. The hurricane is expected to gradually work its way through the ridge and, in 24 to 48 hours, begin to move northeastward and east-northeastward as it enters the mid-latitude westerlies. The official forecast is close to a consensus of the ECMWF and GFS solutions.
