Severe Tropical Cyclone Tauktae Nears Gujarat

Severe Tropical Cyclone Tauktae neared the Indian state of Gujarat on Sunday night. At 11:00 p.m. EDT on Sunday the center of Tropical Cyclone Tauktae was located at latitude 18.9°N and longitude 71.5°E which put it about 90 miles (145 km) west-southwest of Mumbai, India. Tauktae was moving toward the northwest at 10 m.p.h. (16 km/h). The maximum sustained wind speed was 140 m.p.h. (225 km/h) and there were wind gusts to 165 m.p.h. (270 km/h). The minimum surface pressure was 938 mb.

The core of Tropical Cyclone Tauktae was passing just to the west of Mumbai, India on Sunday night. The core of Tauktae contracted on Sunday as the tropical cyclone continued to intensify. The diameter of the circular eye at the center of Tropical Cyclone Tauktae shrank to 14 miles (22 km). 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 Tauktae. Storms near the core generated upper level divergence that pumped mass away to the north and east of the tropical cyclone.

The circulation around Tropical Cyclone Tauktae was very symmetrical. Winds to hurricane/typhoon force extended out 40 miles (75 km) from the center of Tauktae. Winds to tropical storm force extended out 160 miles (260 km) from the center of circulation. The Hurricane Intensity Index (HII) for Tropical Cyclone Tauktae was 28.3. The Hurricane Size Index (HSI) was 16.0 and the Hurricane Wind Intensity Size Index (HWISI) was 44.3. Tauktae was capable of causing regional severe damage.

Tropical Cyclone Tauktae will move through an environment favorable for a strong tropical cyclone during the next 12 hours. Tauktae will move over water where the Sea Surface Temperatures are near 30°C. It will move the northwestern 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 is likely to maintain its intensity during the next 12 hours unless an eyewall replacement cycle begins. If the inner end of a rainband wraps around the existing eye and eyewall, then an eyewall replacement cycle could cause Tauktae to weaken.

Tropical Cyclone Tauktae will move around the northwestern part of a high pressure system over India. The high will steer the Tauktae toward the north-northwest during the next 12 hours. 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 Maharastra and Gujarat. Tropical Cyclone Tauktae could approach the coast of Gujarat near Diu in 12 hours. Tauktae is likely to be the equivalent of a major hurricane when the center nears the coast. Tropical Cyclone Tauktae will be capable of producing severe damage in Gujarat. Tauktae could cause a storm surge of up to 13 feet (4 meters) on the coast of Gujarat. Locally heavy rain could cause flash floods.
