Two tropical cyclones churned over the Arabian Sea on Tuesday night. At 10:00 p.m. EST on Tuesday the center of Tropical Cyclone 06A was located at latitude 7.4°N and longitude 57.6°E which put it about 530 miles (855 km) east of Eyl, Somalia. The tropical cyclone was moving toward the northeast at 1 m.p.h. (2 km/h). The maximum sustained wind speed was 40 m.p.h. (65 km/h) and there were wind gusts to 50 m.p.h. (80 km/h). The minimum surface pressure was 1003 mb.
At 10:00 p.m. EST on Tuesday the center of Tropical Cyclone 07A was located at latitude 14.6°N and longitude 69.1°E which put it about 450 miles (725 km) southwest of Mumbai, India. The tropical cyclone was moving toward the northwest at 9 m.p.h. (15 km/h). The maximum sustained wind speed was 50 m.p.h. (80 km/h) and there were wind gusts to 65 m.p.h. (105 km/h). The minimum surface pressure was 997 mb.
The circulation around Tropical Cyclone 06A exhibited more organization on Tuesday night. More thunderstorms developed near the center of circulation. There were more thunderstorms in bands in the northern half of the tropical cyclone, but thunderstorms were forming in bands in the southern half of the circulation. Storms near the center of circulation were generating upper level divergence which was pumping mass away from the tropical cyclone. Winds to tropical storm force extended out 110 miles (185 km) from the center.
Tropical Cyclone 06A will move through an environment favorable for intensification during the next 24 hours. The tropical cyclone will move over water where the Sea Surface Temperature is near 28°C. It will move near the western end of an upper level ridge centered over southern India. The ridge will produce southerly winds which will blow toward the top of the circulation. Those winds will cause moderate vertical wind shear, and the wind shear will inhibit intensification, but Tropical Cyclone 06A will likely strengthen during the next 24 hours.
Tropical Cyclone 06A is currently in an area where the steering winds are weak and it moved little on Tuesday. A second ridge of high pressure is forecast to build north of the tropical cyclone during the next several days. The second ridge will steer Tropical Cyclone 06A toward the west. On its anticipated track Tropical Cyclone 06A could approach the coast of Somalia in three days.
Tropical Cyclone 07A developed more quickly on Tuesday. The inner end of a rainband wrapped part of the way around the center of circulation. Another band of strong thunderstorms formed in the eastern half of the circulation. Storms near the center of circulation generated upper level divergence which was pumping mass away to the north of the tropical cyclone. Winds to tropical storm force extended out 85 miles (135 km) from the center or circulation.
Tropical Cyclone 07A will also move through an environment favorable for intensification during the next 24 hours. The tropical cyclone will move over water where the Sea Surface Temperature is near 28.5°C. The upper level ridge centered over southern India will also produce southerly winds which will cause some vertical wind shear around Tropical Cyclone 07A. The shear will inhibit intensification, but Tropical Cyclone 07A is also likely to strengthen during the next 24 hours.
The ridge over southern India will steer Tropical Cyclone 07A toward the northwest during the next 24 hours. On its anticipated track Tropical Cyclone 07A will move roughly parallel to the west coast of India.
