Tropical Cyclone Kyant Forms Over Bay of Bengal

Tropical Cyclone Kyant formed over the Bay of Bengal on Tuesday.  At 11:00 a.m. EDT on Tuesday the center of Tropical Cyclone Kyant was located at latitude 16.6°N and longitude 90.4°E which put it about 480 miles (770 km) east of Vishakhapatnam, India.  Kyant was moving toward the west at 7 m.p.h. (11 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 994 mb.

A cluster of thunderstorms persisted over the eastern Bay of Bengal during the past few days, but strong upper level easterly winds prevented the development of the system.  The upper level winds began to diminish on Monday and a low level circulation center began to develop on the eastern edge of the area of thunderstorms.  When the upper level winds became weaker, then thunderstorms were able to develop closer to the center of circulation.  The system acquired the structural characteristics associated with a tropical cyclone and the India Meteorological Department named it Kyant.

The circulation of Tropical Cyclone Kyant is still organizing.  Some vertical wind shear continues because of easterly upper level winds being generated by a ridge northeast of the tropical cyclone.  The shear is causing more of the thunderstorms to form in the western half of the circulation.  However, additional thunderstorms have developed closer to the center in recent hours and some spiral rainbands have formed.  The thunderstorms near the center are generating upper level divergence which is starting to pump out mass in all directions.

Tropical Cyclone Kyant will be moving through a favorable environment during the next several days.  It will move over water where the Sea Surface Temperature is near 30°C.  The upper level winds should remain weaker, and the vertical wind shear will not be strong enough to prevent strengthening.  Tropical Cyclone Kyant is likely to intensify and it could undergo a period of rapid intensification.

The upper level ridge is steering Tropical Cyclone Kyant toward the west and that general motion is expected to continue.  On its anticipated track Tropical Cyclone Kyant could approach the east coast of India in about 48 hours.  It could bring strong winds and very heavy rain to portions of eastern India later this week.
