#984020 (Received by flhurricane at: 11:06 AM 25.Sep.2019) TCDAT5 Post-Tropical Cyclone Jerry Discussion Number 33 NWS National Hurricane Center Miami FL AL102019 1100 AM AST Wed Sep 25 2019 Jerry remains devoid of deep convection in an environment of dry mid-level air and strong westerly shear. Data from a new scatterometer pass indicate that the maximum winds are no more than 35 kt, and even that value could be generous. The system should remain in a hostile environment for the next few days, and simulated satellite imagery from the global models suggest that no significant deep convection will redevelop within it. Therefore the official intensity forecast calls for the cyclone to gradually spin down over the next 2-3 days. The NHC intensity forecast is just slightly below the model consensus. The cyclone has turned toward the east-northeast with some increase in forward speed, and the initial motion estimate is 060/8 kt. Jerry should continue to move east-northeastward, to the south of the main belt of mid-latitude westerlies, for the next day or two. Later in the forecast period, the weak cyclone is expected to turn east-southeastward along the northeastern periphery of a subtropical high pressure area, and dissipate. The official track forecast continues to follow the NOAA corrected consensus guidance rather closely. Key Messages: 1. Tropical-storm-force winds are expected on Bermuda later today. Large swells are also expected to affect the coast of Bermuda during the next few days. These swells could cause life-threatening rip currents. See products issued by the Bermuda Weather Service for more information.
