Hurricane Lorenzo Forecast Discussion Number 26

Issued at 800 PM AST Sat Sep 28 2019 000 WTNT43 KNHC 290006 TCDAT3 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.

Interests in the Azores should monitor the progress of Lorenzo. DISCUSSION AND OUTLOOK ---------------------- At 800 PM AST (0000 UTC), the center of Hurricane Lorenzo was located near latitude 23.8 North, longitude 45.0 West. Lorenzo is moving toward the north near 10 mph (17 km/h), and this motion is expected to continue through tonight. A turn toward the north-northeast is forecast on Sunday, followed by a faster motion toward the northeast beginning Monday or Tuesday. On the forecast track, the center of Lorenzo will be approaching the Azores on Tuesday. Satellite data indicate that the maximum sustained winds have increased to near 145 mph (230 km/h) with higher gusts. Lorenzo is a category 4 hurricane on the Saffir-Simpson Hurricane Wind Scale. Fluctuations in intensity are possible tonight and early Sunday. Lorenzo is expected to gradually weaken Sunday night through Tuesday, but it will remain a large and potent hurricane while it approaches the Azores. Lorenzo is a large hurricane. Hurricane-force winds extend outward up to 50 miles (85 km) from the center, and tropical-storm-force winds extend outward up to 275 miles (445 km). The estimated minimum central pressure is 942 mb (27.82 inches). HAZARDS AFFECTING LAND ---------------------- SURF: Swells generated by Lorenzo are affecting portions of the northeastern coast of South America and the Lesser Antilles and are expected to spread westward to portions of the north coasts of the Greater Antilles, the Bahamas, Bermuda, and the east coast of the United States during the next few days. Swells are also expected to build near the Azores on Sunday and Monday. These swells are likely to cause life-threatening surf and rip current conditions.
