Issued at 200 AM PDT TUE JUL 26 2016 000 WTPZ43 KNHC 260845 TCDEP3 HURRICANE GEORGETTE DISCUSSION NUMBER 19 NWS NATIONAL HURRICANE CENTER MIAMI FL EP082016 200 AM PDT TUE JUL 26 2016 Georgette continues to weaken at a fast pace this morning. Central deep convection has been diminishing in areal coverage and intensity, and using a blend of Dvorak T- and Current Intensity-numbers from TAFB and SAB, the current intensity is set at 70 kt. Georgette will be moving over sub-25 deg C waters and through an environment of dry mid-level air, so continued weakening is expected. The cyclone's intensity should drop to tropical storm status today, and below storm strength within 48 hours or sooner. The official intensity forecast is a little above the latest numerical model consensus, IVCN. The slow forward motion continues, and the initial motion estimate is northwestward or 315/4 kt. Georgette is located to the south of a weakness in the subtropical ridge and this has likely contributed to the slow northwestward motion. The ridge is predicted to build somewhat, and as the weakening tropical cyclone responds more to the lower-level flow, a gradual turn to the left with some increase in forward speed is expected during the forecast period. The official forecast is only slightly slower than the previous one albeit along about the same trajectory. This is close to the latest model consensus.
