Issued at 300 PM CST Thu Nov 07 2024 000 WTNT43 KNHC 072035 TCDAT3 Hurricane Rafael Discussion Number 17 NWS National Hurricane Center Miami FL AL182024 300 PM CST Thu Nov 07 2024 Rafael has made a resurgence this afternoon. The hurricane has apparently mixed out some of the dry air from earlier today and become better organized, with a ragged eye that has emerged in satellite imagery and a more cohesive ring of deep convection surrounding its center. On the last pass through the eye earlier this afternoon, the Air Force Hurricane Hunters found that the central pressure had fallen several millibars from earlier passes. They also reported a few observations of 700-mb flight-level winds in excess of 100 kt, with a peak of 107 kt. These data support raising the initial intensity to 90 kt. Another Air Force Hurricane Hunter aircraft will investigate Rafael this evening. The improved structure of the hurricane could make it more resilient to the negative effects of dry air and westerly shear in the near term, so some additional strengthening cannot be ruled out tonight. However, the overall model trends favor weakening through much of the 5-day forecast period as Rafael moves into a drier mid-level environment and encounters stronger shear by this weekend. The updated NHC intensity prediction has been nudged upward through 24 h and downward at later forecast times, but still lies near or above the simple- and corrected-consensus aids. It is possible that the hostile environmental conditions could cause Rafael to weaken even faster and lose organized convection by the end of the 5-day period. Rafael is moving west-northwestward (295/8 kt) around a mid-level ridge over the southwestern Atlantic and the Florida Peninsula. As this ridge builds to its north, the hurricane is expected to move generally westward through Saturday. There is still quite a bit of track forecast uncertainty thereafter, with larger than normal spread among the various track models. Many of the models (including the ECMWF, UKMET, and regional hurricane models) slow Rafael down and turn it southwestward in response to ridging over the western Gulf and northern Mexico. However, the GFS and Canadian models show a slow northward turn between an upper trough over the central U.S. and a ridge to the east. No major changes were made to the NHC track forecast this cycle, which continues to favor the former scenario. However, future larger adjustments to the track forecast could be required. If model solutions like the GFS were to verify, Rafael would encounter a stronger shear environment and likely weaken faster than shown in the official NHC forecast. Key Messages: 1. Swells generated by Rafael are likely to cause life-threatening surf and rip current conditions along the Gulf Coast for the next few days. 2. Rafael is forecast to move slowly over the south-central Gulf of Mexico this weekend and early next week. Interests in the southern and southwestern Gulf of Mexico should monitor the progress of this system.

Issued at 900 AM CST Thu Nov 07 2024 000 WTNT43 KNHC 071453 TCDAT3 Hurricane Rafael Discussion Number 16 NWS National Hurricane Center Miami FL AL182024 900 AM CST Thu Nov 07 2024 The Air Force and NOAA Hurricane Hunters have been investigating Rafael this morning. Tail Doppler Radar data and reports from the flight crews, in addition to earlier passive microwave imagery, indicate the eyewall has opened up to the south and southwest of the center. This is likely due to the negative influences of some drier mid-level air and westerly shear. The Air Force Hurricane Hunters have reported peak 700-mb flight-level winds of 92 kt, and dropsonde data indicate the central pressure has risen slightly to around 971 mb. Given the latest flight-level wind data and some erosion of the eyewall convection, the initial intensity is lowered to 85 kt. The hurricane is expected to move into an even drier airmass over the next few days, with at least weak to moderate westerly shear over the system. So despite 27-28 deg C SSTs over the southern Gulf of Mexico, some additional weakening is forecast through this weekend into early next week. Rafael should remain a hurricane for the next couple of days, but some downward adjustments were made to the NHC intensity forecast to bring it closer to the latest multi-model consensus aids. Even still, the NHC forecast lies on the higher side of the guidance envelope. Recent aircraft fixes indicate Rafael is beginning a leftward turn, and the initial motion estimate is west-northwestward at 295/8 kt. The hurricane should move westward over the next couple of days as a mid-level ridge builds to its north. Then, there is still some spread in the track guidance with a bifurcation in model solutions. Most of the models (including the ECMWF, UKMET, and regional hurricane models) show Rafael turning southwestward in response to a narrow ridge building to its northwest. But, the GFS and Canadian models still suggest a northward turn ahead of a slightly deeper upper trough over the central United States. The NHC prediction continues to favor the southern solutions and is similar to the previous forecast, in agreement with the majority of track models and consensus aids. There remains above average uncertainty in the future track of Rafael, and additional adjustments to subsequent official track forecasts are likely. If the northern model solutions were to verify, Rafael would likely encounter even more hostile environmental conditions and weaken faster than shown in the official NHC forecast. Key Messages: 1. Hurricane Rafael will continue to bring periods of heavy rain to western Cuba today. Flash flooding and mudslides are possible along the higher terrain. 2. Rafael is forecast to move slowly over the south-central Gulf of Mexico this weekend and early next week. Interests in the southern and southwestern Gulf of Mexico should monitor the progress of this system.
