Tropical Storm Rafael Forecast Discussion Number 26
2024-11-09 21:58:03| National Hurricane Center (Atlantic)
Issued at 300 PM CST Sat Nov 09 2024 000 WTNT43 KNHC 092057 TCDAT3 Tropical Storm Rafael Discussion Number 26 NWS National Hurricane Center Miami FL AL182024 300 PM CST Sat Nov 09 2024 The center of Rafael has become exposed to the southwest of its associated convective mass in visible satellite images. The low-level circulation is becoming broader and less defined, and the cold overcast from the sheared convection has contracted and warmed this afternoon. Overall, the storm appears less organized as it contends with westerly shear and a dry mid-level environment. A partial ASCAT pass showed 35-40 kt winds in the northeast quadrant, but may not have sampled the area of strongest winds. The initial intensity is held at 45 kt, which is consistent with a blend of the latest subjective and objective satellite intensity estimates. The storm should continue weakening tonight due to the negative effects of increasing westerly shear and continued intrusions of dry mid-level air. In fact, the latest simulated satellite imagery from the GFS and ECMWF models suggest Rafael could become devoid of convection as early as Sunday. The official NHC forecast now shows post-tropical/remnant low status at 36 h, but further timing adjustments could be necessary if current trends continue. Rafael is beginning to slow down (300/4 kt), and the storm is likely to meander within weakening steering currents over the central Gulf of Mexico tonight and Sunday. Then, the shallow vortex should become steered by the prevailing low-level flow on Monday and move toward the south and south-southwest through the middle of next week. Most of the guidance shows the remnant low spinning down and opening into a trough over the southwestern Gulf of Mexico late in the 5-day forecast period, and the NHC forecast shows dissipation by 120 h. 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. 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.

SUMMARY OF 300 PM CST...2100 UTC...INFORMATION ---------------------------------------------- LOCATION...25.5N 91.7W ABOUT 315 MI...510 KM NNW OF PROGRESO MEXICO MAXIMUM SUSTAINED WINDS...50 MPH...85 KM/H PRESENT MOVEMENT...WNW OR 300 DEGREES AT 5 MPH...7 KM/H MINIMUM CENTRAL PRESSURE...1000 MB...29.53 INCHES WATCHES AND WARNINGS -------------------- There are no coastal watches or warnings in effect. DISCUSSION AND OUTLOOK ---------------------- At 300 PM CST (2100 UTC), the center of Tropical Storm Rafael was located near latitude 25.5 North, longitude 91.7 West. Rafael is moving toward the west-northwest near 5 mph (7 km/h). The storm is expected to slow down and 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 50 mph (85 km/h) with higher gusts. Weakening is expected through early next week. Rafael is forecast to degenerate to a post-tropical remnant low by early Monday. Tropical-storm-force winds extend outward up to 115 miles (185 km) from the center. The estimated minimum central pressure is 1000 mb (29.53 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 900 PM CST. $$ Forecaster Reinhart

Near the Bahamas: A concentrated area of showers and thunderstorms a couple of hundred miles east of the central Bahamas is associated with a trough of low pressure. Some gradual development of this system is possible during the next day or so before it moves into unfavorable environmental conditions on Sunday. Regardless of development, locally heavy rains and gusty winds are possible as it moves generally westward across the Bahamas through Sunday. * Formation chance through 48 hours...low...10 percent. * Formation chance through 7 days...low...10 percent. $$ Forecaster Cangialosi

Tropical Storm Rafael Forecast Discussion Number 25
2024-11-09 15:43:54| National Hurricane Center (Atlantic)
Issued at 900 AM CST Sat Nov 09 2024 000 WTNT43 KNHC 091443 TCDAT3 Tropical Storm Rafael Discussion Number 25 NWS National Hurricane Center Miami FL AL182024 900 AM CST Sat Nov 09 2024 Rafael is a sheared tropical storm. High-resolution AMSR2 passive microwave images received after the previous advisory showed the northeastward tilt of the vortex with height. Recent data from the Air Force Hurricane Hunters confirm the surface center lies on the southwestern edge of the deep convective mass over the central Gulf of Mexico. The strongest winds are likely confined to the northeast quadrant of the storm underneath this sheared convection. Dropsonde data indicate the central pressure has risen to around 999 mb, and the initial intensity is lowered to 45 kt based on flight-level winds from the aircraft. The storm is likely to continue weakening due to unfavorable environmental conditions. Moderate westerly shear (15-20 kt) through Sunday and mid-level relative humidities falling below 40 percent should make it difficult for Rafael to become better organized and sustain deep convection going forward. Steady weakening is shown in the NHC intensity forecast through Sunday, and Rafael is now predicted to become a post-tropical remnant low in 48 h. Rafael is moving west-northwestward (290/5 kt), but the storm is expected to slow down and meander over the central Gulf of Mexico within weakening steering currents during the next 24-36 h. As Rafael becomes weak and shallow, the track guidance agrees on a turn toward the south and south-southwest within the low-level flow through the middle of next week. Only minor adjustments were made to the NHC track forecast, which lies near the center of the guidance envelope in good agreement with the TVCA simple consensus. 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 the Upper Texas Coast into Southwest and Central Louisiana through Sunday 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.
