Tropical Storm Ophelia (AL17)

Tropical Storm Ophelia (AL17), the fifteenth named storm of the 2017 North Atlantic hurricane season, formed yesterday, Monday October 9, over open water in the eastern Atlantic . Ophelia is currently a tropical storm on the Saffir-Simpson Hurricane Wind Scale (SSHWS), with maximum sustained wind speeds of around 52 (83 km/hr). The system is forecast by the National Hurricane Center (NHC) to intensify to a hurricane in the coming 48 hours as it tracks through favorable environmental conditions. At this time, the Azores, an autonomous region of Portugal, are located within the NHC cone of uncertainty and may experience tropical storm force winds as the system approaches later this week. Impacts (as of 09:00 UTC on Tuesday October 10). Tropical Storm Ophelia is currently located over open water in the eastern Atlantic and has yet to impact land. NHC Status and Parameters (as of 09:00 UTC on Tuesday October 10). The National Hurricane Center (NHC) estimates that the center of Ophelia is at approximately 31.54°N, 38.48°W, about 790 mi (1270 km) WSW of The Azores. The storm has maximum sustained wind speeds of 52 mph (83 km/hr), equivalent to a tropical storm on the Saffir-Simpson Hurricane Wind Scale (SSHWS). Ophelia has a minimum central pressure of 1002 hPa and is trackingsoutheast at around 3 mph (6 km/hr). Tropical storm force winds from the center: NE 105 mi (165 km); SE 70 mi (110 km); SW 45 mi (75 km); NW 80 mi (130 km).Watches and Warnings . There are no Hurricane or Tropical Storm Warnings or Watches in effect at this time. Meteorological Discussion (as of 09:00 UTC on Tuesday October 10). Ophelia is currently located over open water in the eastern Atlantic . The system is currently tracking west-southwest, but Ophelia is expected to turn northeast to east-northeast as a mid- to upper-level trough approaches from the northwest. Environmental conditions are favorable for intensification, with low wind shear and warm sea-surface temperatures. As a result, the NHC expects the system to strengthen to become a hurricane in the coming 48 hours . Should Ophelia attain hurricane status as the NHC forecasts, it would become the tenth consecutive named storm this season to attain hurricane status. At this time, the Azores, an autonomous region of Portugal, are located within the NHC cone of uncertainty and may experience tropical storm force winds as the system approaches later this week. The NHC track and intensity guidance is in good agreement with the operational model guidance.
