ZCZC MIATCDAT3 ALL TTAA00 KNHC DDHHMM Hurricane Lorenzo Special Discussion Number 26 NWS National Hurricane Center Miami FL AL132019 800 PM AST Sat Sep 28 2019 The satellite presentation of Lorenzo has improved throughout this evening, and the ring of cloud tops surrounding the eye have become wider and colder. This has resulted in both subjective and objective satellite intensity estimates increasing to a 6.5 on the Dvorak scale, indicative of a 125 kt hurricane. Based on this data, a special advisory is being issued at this time to increase the initial intensity, and the 12-hour and 24-hour forecast wind speeds. No other changes were required to the previous track or intensity forecast. Key Messages: 1. Lorenzo is a large hurricane, and its hurricane- and tropical-storm-force wind fields are expected to expand further during the next several days. Regardless of Lorenzo's exact track near the Azores, strong winds are becoming increasingly likely on the islands Tuesday night and Wednesday, and residents there should monitor the progress of the hurricane. 2. Large swells generated by Lorenzo will continue to spread across much of the western and northern parts of the Atlantic basin during the next few days. These swells will produce life-threatening surf and rip currents.
