Tropical Cyclone Tauktae Strengthens to Equivalent of Hurricane/Typhoon

Tropical Cyclone Tauktae strengthened to the equivalent of a hurricane/typhoon over the Arabian Sea south of Mumbai on Saturday. At 5:00 p.m. EDT on Saturday the center of Tropical Cyclone Tauktae was located at latitude 14.9°N and longitude 72.8°E which put it about 300 miles (485 km) south of Mumbai, India. Tauktae was moving toward the north-northwest at 8 m.p.h. (13 km/h). The maximum sustained wind speed was 75 m.p.h. (120 km/h) and there were wind gusts to 90 m.p.h. (145 km/h). The minimum surface pressure was 979 mb.

Tropical Cyclone Tauktae strengthened steadily on Saturday and it intensified to the equivalent of a hurricane/typhoon. The inner end of a rainband wrapped around the center of Tauktae and an eye was visible on the India Meteorological Department’s radar at Goa and on satellite imagery. The eye was surrounded by a ring of strong thunderstorms and the strongest winds were occurring in that ring of storms. Bands of showers and thunderstorms were revolving around the core of Tropical Cyclone Tauktae. Storms near the core generated upper level divergence that pumped mass away to the north and east of the tropical cyclone. Winds to hurricane/typhoon force extended out 20 miles (30 km) from the center of Tauktae. Winds to tropical storm force extended out 160 miles (260 km) from the center of circulation.

Tropical Cyclone Tauktae will move through an environment very favorable for intensification during the next 36 hours. Tauktae will move over water where the Sea Surface Temperatures are near 30°C. It will move the western portion of an upper level ridge over India and the eastern Arabian Sea. The upper level winds will be weak and there will be little vertical wind shear. Tropical Cyclone Tauktae will continue to intensify and it could strengthen to the equivalent of a major hurricane within 36 hours. Since an inner core with an eye and an eyewall has developed, rapid intensification could occur.

Tropical Cyclone Tauktae will move around the western side of a high pressure system over India. The high will steer the tropical cyclone toward the north-northwest during the next 36 hours. On its anticipated track the core of Tropical Cyclone Tauktae will pass west of Mumbai, India. Rainbands on the eastern side of the tropical cyclone could produce gusty winds, drop locally heavy rain and bring high waves to the west coast of India in Karnataka, Goa and Maharastra. Tropical Cyclone Tauktae could approach the coast of Gujarat near Diu in 36 hours. Tauktae could be the equivalent of a major hurricane when the center nears the coast.
