Hurricane Pablo Forecast Discussion Number 8

Issued at 1100 AM AST Sun Oct 27 2019 000 WTNT43 KNHC 271450 TCDAT3 Hurricane Pablo Discussion Number 8 NWS National Hurricane Center Miami FL AL182019 1100 AM AST Sun Oct 27 2019 Satellite imagery shows that Pablo has continued to maintain a small eye, and that the eyewall cloud tops have recently cooled. In addition, early morning microwave satellite intensity estimates, as well as the CIMSS satellite consensus, indicate that Pablo has become a hurricane. The initial intensity is increased to 65 kt as a blend between the subjective estimate from TAFB and the higher SATCON estimate, and it is possible this is a little conservative. The intensification has occurred while Pablo is over sea surface temperatures of 19-20C, and it is likely that cold mid- to upper-level air temperatures have allowed the cyclone to maintain deep convection and strengthen over water temperatures where tropical cyclones normally weaken. The initial motion is now 030/28. The cyclone is expected to turn northward and slow its forward motion as it approaches a frontal system to the north during the next 12-24 h, and this will be followed by a turn toward the northwest as a large mid-latitude low over the north central Atlantic becomes the main steering mechanism. The track guidance has again shifted a little to the east, and the new forecast track is also nudged a little to the east of the previous track. Like the previous forecast, it lies close to the various consensus models. Pablo should encounter even colder water along the forecast track, and global model guidance suggests it should merge with the frontal system between 12-24 h. This combination should cause Pablo to weaken and become an extratropical cyclone. Thereafter, the system should be absorbed by the much larger low to its west between 48-72 h.
