Tropical Storm Rafael Forecast Discussion Number 29

Sun, 11/10/2024 - 9:34am
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.

Tropical Storm Rafael Forecast Discussion Number 28

Sun, 11/10/2024 - 3:30am
Issued at 300 AM CST Sun Nov 10 2024 000 WTNT43 KNHC 100830 TCDAT3 Tropical Storm Rafael Discussion Number 28 NWS National Hurricane Center Miami FL AL182024 300 AM CST Sun Nov 10 2024 Rafael continues to gradually weaken. Satellite images show that the low-level center remains exposed, with an area of shrinking deep convection located well east of the center. The initial intensity is reduced to 35 kt, in accordance with nearby buoy observations and recent satellite intensity estimates. Gradual weakening is expected due to a harsh environment of very dry air aloft and wind shear. The system should lose organized deep convection later today and become a post-tropical cyclone in about 24 hours. Only small changes were made to the previous intensity forecast. The storm is basically drifting to the north-northwest now, and Rafael is forecast to make a small clockwise loop during the next day or so over the central Gulf of Mexico in light steering currents. After that time, the low-level flow should steer the cyclone or its remnants southward and southwestward, and the remnant low should open up into a trough of low pressure in about 3 days. The new forecast is a touch east of the previous one in the near term and also shows dissipation a little sooner based on the latest model solutions. 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. Also, the interaction of distant moisture from Rafael with a slow-moving front will cause heavy rainfall and potentially significant flash flooding across portions of southwestern and central Louisiana through this morning. Key Messages: 1. Swells generated by Rafael are likely to cause life-threatening surf and rip current conditions along the Gulf Coast through the weekend.

Tropical Storm Rafael Forecast Discussion Number 27

Sat, 11/09/2024 - 9:32pm
Issued at 900 PM CST Sat Nov 09 2024 000 WTNT43 KNHC 100232 TCDAT3 Tropical Storm Rafael Discussion Number 27 NWS National Hurricane Center Miami FL AL182024 900 PM CST Sat Nov 09 2024 Rafael remains sheared this evening, with the remaining convection located to the northeast of the exposed low-level center. The circulation center itself is broad and appears to have multiple small vorticity center embedded in it. The initial intensity is decreased to 40 kt based on a blend of the various subjective and objective satellite intensity estimates. These winds are likely occurring in the area of convection northeast of the center and northwest of buoy 42001. The initial motion is now a slow 325/3. during the next 36 h or so, Rafael should make a small clockwise loop over the central Gulf of Mexico. After that time, the low-level flow should steer the cyclone or its remnants southward and southwestward. One change in the track guidance is that that the GFS and HWRF models turn the system move westward after 60 h and wind up to the north of the rest of the guidance. Overall, the new forecast track is little changed from the previous track and lies near the consensus models. Rafael should continue to weaken due to a combination of southwesterly shear and dry air entrainment. Simulated satellite imagery from the GFS and ECMWF continue to indicate that the associated convection will dissipate between 24-36 h, with the circulation becoming elongated. Based on this, the intensity forecast calls for the cyclone to degenerate to a remnant low pressure area by 36 h, with final dissipation by 120 h as suggested by most of the global models. The new intensity forecast has only minor tweaks from the previous forecast. 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. Also, the interaction of distant moisture from Rafael with a slow-moving front will cause heavy rainfall and potentially significant flash flooding across portions of Southwest and Central Louisiana through Sunday morning.

DISCUSSION AND OUTLOOK ---------------------- At 900 PM CST (0300 UTC), the center of Tropical Storm Rafael was located near latitude 25.7 North, longitude 91.7 West. Rafael is moving toward the northwest near 3 mph (6 km/h). The storm is expected to meander over the central Gulf of Mexico through Sunday night, then turn toward the south and south-southwest on Monday and Tuesday. Maximum sustained winds are near 45 mph (75 km/h) with higher gusts. Weakening is expected through early next week, and Rafael is forecast to degenerate to a post-tropical remnant low on Monday. Tropical-storm-force winds extend outward up to 115 miles (185 km) from the center. The estimated minimum central pressure is 1002 mb (29.59 inches). HAZARDS AFFECTING LAND ---------------------- Key messages for Rafael can be found in the Tropical Cyclone Discussion under AWIPS header MIATCDAT3 and WMO header WTNT43 KNHC and on the web at hurricanes.gov/text/MIATCDAT3.shtml SURF: Swells generated by Rafael will continue impacting portions of the northern and western Gulf Coast through the weekend. These swells are likely to cause life-threatening surf and rip current conditions. Please consult products from your local weather office. RAINFALL: Rainfall indirectly associated with the moisture from Rafael is expected to lead to 3 to 6 inches of rain, with local amounts to 10 inches, across portions of Southwest and Central Louisiana through Sunday morning. This rain will lead to potentially significant flash flooding. NEXT ADVISORY ------------- Next complete advisory at 300 AM CST. $$ Forecaster Beven
