Tropical Cyclone Forms Over the Arabian Sea

A tropical cyclone formed over the Arabian Sea on Friday evening. At 11:00 p.m. EDT on Friday the center of Tropical Cyclone 05A was located at latitude 10.0°N and longitude 58.8°E which put it about 600 miles (965 km) southeast of Salalah, Oman. The tropical cyclone was moving toward the west-northwest at 8 m.p.h. (13 km/h). The maximum sustained wind speed was 60 m.p.h. (95 km/h) and there were wind gusts to 75 m.p.h. (120 km/h). The minimum surface pressure was 997 mb.

The circulation around Tropical Cyclone 05A organized quickly over the Arabian Sea on Friday evening. The inner end of a rainband wrapped around the center of the tropical cyclone’s circulation. A broken ring of thunderstorms surrounded the center of circulation and the strongest winds were occurring in that ring of storms. Bands of showers and thunderstorms were revolving around the center of circulation. Storms near the center generated upper level divergence that pumped mass away from the tropical cyclone. Winds to tropical storm force extended out 140 miles (220 km) from the center of Tropical Cyclone 05A.

Tropical Cyclone 05A will move through an environment very favorable for intensification during the next 24 hours. The tropical cyclone will move over water where the Sea Surface Temperatures are near 29°C. It will move through a region where the upper level winds are weak and there will be little vertical wind shear. Tropical Cyclone 05A is likely to intensify to the equivalent of a hurricane/typhoon during the next 24 hours.

Tropical Cyclone 05A will move around the southwestern part of a high pressure system over South Asia. The high pressure system will steer the tropical cyclone toward the northwest during the next 24 hours. On its anticipated track, Tropical Cyclone 05A will move closer to Oman.
