Tropical Cyclone Michaung Develops over Southwest Bay of Bengal

Tropical Cyclone Michaung developed over the southwestern Bay of Bengal on Saturday evening. At 10:00 p.m. EST on Saturday the center of Tropical Cyclone Michaung was located at latitude 11.7°N and longitude 82.3°E which put it about 185 miles (300 km) southeast of Chennai, India. Michaung was moving toward the west-northwest at 7 m.p.h. (11 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 1001 mb.

A low pressure system over the southwestern Bay of Bengal strengthened on Saturday evening and the India Meteorological Department designated the system as Tropical Cyclone Michaung. Bands of showers and thunderstorms were revolving around the center of Michaung’s circulation. Storms near the center of circulation generated upper level divergence that pumped mass away from the tropical cyclone. The removal of mass caused the surface pressure to decrease. Winds to tropical storm force extended out 60 miles (95 km) from the center of Tropical Cyclone Michaung.

Tropical Cyclone Michaung will move through an environment favorable for intensification during the next 24 hours. Michaung will move over water where the Sea Surface Temperatures are near 29°C. It will move under the southwestern part of an upper level ridge over the Bay of Bengal. The upper level ridge will produce easterly winds that will blow toward the top of Michaung’s circulation. Those winds will cause some vertical wind shear, but the wind shear will not be enough to prevent intensification. Tropical Cyclone Michaung system will intensify during the next 24 hours. Michaung could strengthen to the equivalent of a hurricane/typhoon.

Tropical Cyclone Michaung will move around the southwestern part of a high pressure system over East Asia. The high pressure system will steer Michaung toward the northwest during the next 24 hours. On its anticipated track, Tropical Cyclone Michaung will move toward the coast of southeast India. The center of Michaung could be east of Chennai in 24 hours. Tropical Cyclone Michaung will bring strong winds and locally heavy rain to parts of southeast India. Heavy rain could cause floods in some locations. The India Meteorological Department issued Cyclone Alerts for the coasts of Andhra Pradesh, North Tamil Nadu and Puducherry.
