Rafael (AL182024) DATA RELEASED: 11/10/2024 3:00:00 AM UTC
Copy of official data 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.
