Tropical Storm Rafael Forecast Discussion Number 29
Issued at 900 AM CST Sun Nov 10 2024 000 WTNT43 KNHC 101434 TCDAT3 Tropical Storm Rafael Discussion Number 29 NWS National Hurricane Center Miami FL AL182024 900 AM CST Sun Nov 10 2024 Convection has continued to weaken this morning and move farther away to the east of the low-level center. Rafael’s remaining convection is all located more than 75 miles east-northeast of the center. A recent observation of a 33-kt 1-min wind from buoy 42001 indicates that Rafael still likely has tropical-storm-force winds. Gradual weakening is expected to continue because Rafael is located within a very dry environment, which is forecast to become even drier over the next 24 to 36 h. The NHC intensity forecast is similar to the previous one and follows the intensity guidance. Simulated satellite imagery from the ECMWF model suggests that Rafael should lose its convection and become a remnant low within the next 12 to 24 h. Rafael is expected to become a remnant low either tonight or on Monday. Rafael has been drifting toward the north-northwest, or 345/3 kt. Rafael will remain over the Gulf of Mexico as it spins down over the next couple of days, performing a small clockwise loop over the central Gulf of Mexico through Monday in weak steering currents, before being pushed southward and southwestward by the low-level flow on Tuesday. The latest NHC track forecast lies close to the consensus models, and only minor tweaks were made to the previous NHC track forecast. The NHC forecast calls for the remnant low of Rafael to open up into a trough and dissipate by mid-week, and this solution is also shown by the latest GFS and ECMWF models. Rafael poses no direct threat to land, but swells from the storm are still contributing to an elevated rip current risk along the northern and western Gulf Coast, and this will likely continue into Monday before subsiding on Tuesday. Key Messages: 1. Swells generated by Rafael are likely to cause life-threatening surf and rip current conditions along portions of the Gulf Coast through the weekend.
