Tropical Cyclone Gulab Redevelops over the Arabian Sea

Tropical Cyclone Gulab redeveloped over the Arabian Sea on Thursday. At 5:00 p.m. EDT on Thursday the center of Tropical Cyclone Gulab was located at latitude 22.8°N and longitude 65.1°E which put it about 175 miles (280 km) south-southwest of Karachi, Pakistan. Gulab was moving toward the west at 15 m.p.h. (24 km/h). The maximum sustained wind speed was 45 m.p.h. (75 km/h) and there were wind gusts to 60 m.p.h. (95 km/h). The minimum surface pressure was 994 mb.

Tropical Cyclone Gulab redeveloped over the Arabian Sea south of Pakistan on Thursday. Gulab originally formed over the northern Bay of Bengal a few days ago. Gulab made landfall on the coast of India near Tekkali and then it moved westward across India. Even though Tropical Cyclone Gulab weakened after it made landfall, the circulation remained relatively intact because of a favorable upper level environment. There was not a lot of vertical wind shear. In fact, upper level divergence continued to pump away mass and allow the surface low pressure system to persist. The circulation began to intensify as Gulab approached the Arabian Sea and it strengthened once the low level center was back over water.

The circulation around Tropical Cyclone Gulab exhibited more organization on Thursday. More thunderstorms developed in bands revolving around the center of Gulab. The strongest thunderstorms were occurring in bands in the southern half of Tropical Cyclone Gulab. Bands in the northern half of the circulation consisted primarily of showers and lower clouds. The northern half of Gulab appeared to be pulling drier air from Asia into its circulation. Winds to tropical storm force extended out 140 miles (220 km) on the northern side of Tropical Cyclone Gulab. Winds to tropical storm force extended out 60 miles (95 km) on the southern side of the circulation.

Tropical Cyclone Gulab will move through an environment favorable for intensification during the next 36 hours. Gulab will move over water where the Sea Surface Temperatures are near 29˚C. It will move under the middle of an upper level ridge over Southwest Asia and the northern Arabian Sea. The upper level winds are weak near the middle of the ridge and there will be little vertical wind shear. Dry air from Asia could continue to limit the development of thunderstorms in the northern half of Gulab. Tropical Cyclone Gulab will intensify during the next 36 hours and it could strengthen to the equivalent of a hurricane/typhoon.

Tropical Cyclone Gulab will move around the southern side of a high pressure system over Southwest Asia. The high will steer Gulab toward the west during the next 36 hours. On its anticipated track Tropical Cyclone Gulab could approach the coast of Oman near Muscat in 60 hours.
