Tropical Cyclone Ditwah Forms Near Sri Lanka

Leave a reply

Tropical Cyclone Ditwah formed over the southwestern Bay of Bengal on Thursday.  At 10:00 a.m. EST on Thursday the center of Tropical Cyclone Ditwah was located at latitude 7.8°N and longitude 81.6°E which put the center about 10 miles (15 km) northwest of Batticaloa, Sri Lanka.  Ditwah was moving toward the northwest at 7 m.p.h. (11 km/h).  The maximum sustained wind speed was 40 m.p.h. (50 km/h) and there were wind gusts to 50 m.p.h. (80 km/h).  The minimum surface pressure was 1002 mb.

A low pressure system over the southwestern Bay of Bengal near Sri Lanka intensified on Thursday and the India Meteorological Department designated the system as Tropical Cyclone Ditwah.

The center of Tropical Cyclone Ditwah was near the east coast of Sri Lanka.  About half of Ditwah’s circulation was over Sri Lanka.  A band of thunderstorms was wrapped around the northern and western sides of the center of Tropical Cyclone Ditwah.  Other bands of showers and thunderstorms were revolving around the center of Ditwah’s circulation.  Storms near the center of Ditwah generated upper level divergence that pumped mass away to the west of the tropical cyclone.  The removal of mass caused the surface pressure to decrease slowly.

The distribution of wind speeds in Tropical Cyclone Ditwah was asymmetrical.  Winds to tropical storm force extended out 175 miles (280 km) in the southern half of Ditwah’s circulation.  Winds to tropical storm force extended out 80 miles (130 km) in the northern side of Tropical Cyclone Ditwah.

Tropical Cyclone Ditwah will move through an environment somewhat favorable for intensification during the next 24 hours.  Ditwah will move over water where the Sea Surface Temperatures are near 29°C.  It will move under the western part of an upper level ridge that is over Southeast Asia and the Bay of Bengal.  The upper level ridge will produce southeasterly winds that will blow toward the top of Ditwah’s circulation.  Those winds will cause moderate vertical wind shear.  The vertical wind shear will inhibit intensification.  The fact that almost half of Ditwah’s circulation is over Sri Lanka will also inhibit intensification.  Tropical Cyclone Ditwah could intensify during the next 24 hours even with moderate vertical wind shear, if the center of its circulation remains over water.

Tropical Cyclone Ditwah will move around the southwestern part of a high pressure system over the Bay of Bengal.  The high pressure system will steer Ditwah toward the northwest during the next 24 hours.  On its anticipated track, the center of Tropical Cyclone Ditwah will move along the coast of northeastern Sri Lanka.  Ditwah could approach the coast of India near Chennai within 72 hours.

Tropical Cyclone Ditwah will produce strong winds and heavy rain over Sri Lanka.  Heavy rain will cause flash floods in some locations.

Tropical Cyclone Montha Forms over Bay of Bengal

Tropical Cyclone Montha formed over the Bay of Bengal on Sunday.  At 5:00 p.m. EDT on Sunday the center of Tropical Cyclone Montha was located at latitude 11.6°N and longitude 85.2°E which put the center about 380 miles (615 km) east-southeast of Chennai, India.  Montha was moving toward the west at 8 m.p.h. (13 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 998 mb.

A low pressure system over the Bay of Bengal strengthened on Sunday and the India Meteorological Department designated the system as Tropical Cyclone Montha.

The distribution of thunderstorms in Tropical Cyclone Montha was asymmetrical.  Thunderstorms were occurring in bands in the western side of Montha’s circulation.  The bands in the eastern side of Tropical Cyclone Montha consisted primarily of showers and lower clouds.  Storms near the center of Montha generated upper level divergence that pumped mass away to the west of the tropical cyclone.  The removal of mass caused the surface pressure to decrease.

The strongest winds were occurring in the southwestern part of Tropical Cyclone Montha.  Winds to tropical storm force extended out 85 miles (135 km) in the southwestern quadrant of Montha’s circulation.  The winds in the other parts of Tropical Cyclone Montha were blowing at less than tropical storm force.

Tropical Cyclone Montha will move through an environment somewhat favorable for intensification during the next 24 hours.  Montha will move over water where the Sea Surface Temperatures are near 29°C.  It will move under the southern part of an upper level ridge that is over Southeast Asia.  The upper level ridge will produce easterly winds that will blow toward the top of Montha’s circulation.  Those winds will cause moderate vertical wind shear.  The moderate vertical wind shear will inhibit intensification, but the wind shear may not be enough to prevent intensification.  Tropical Cyclone Montha could intensify a little during the next 24 hours.

Tropical Cyclone Montha will move around the western side of a high pressure system that is over Southeast Asia.  The high pressure system will steer Montha toward the northwest during the next 24 hours.  On its anticipated track, Tropical Cyclone Montha will move toward the east coast of India.

 

Tropical Cyclone Fengal Drops Heavy Rain on Southern India

Tropical Cyclone Fengal dropped heavy rain on parts of southern India on Sunday.  At 4:00 a.m. EST on Sunday the center of Tropical Cyclone Fengal was located at latitude 12.1°N and longitude 79.8°E which put the center about 75 miles (120 km) south-southwest of Chennai, India.  Fengal was moving toward the west-northwest at 3 m.p.h. (5 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 995 mb.

Tropical Cyclone Fengal was dropping heavy rain on Sunday as it moved slowly inland over southern India.  Heavy rain was falling in the east central and northeastern parts of Tamil Nadu.

Tropical Cyclone Fengal was weakening gradually as it moved slowly inland over southern India.  The strongest winds were occurring in the part of Fengal’s circulation that were still over the Bay of Bengal.  Winds to tropical storm force extended out 45 miles (75 km) from the center of Tropical Cyclone Fengal.  The winds in the parts of Fengal’s circulation that were over land were blowing at less than tropical storm force.

Tropical Cyclone Fengal will move around the southern side of a high pressure system over eastern and southern Asia.  The high pressure system will steer Fengal toward the west during the next 48 hours.  On its anticipated track, Tropical Cyclone Fengal will continue to move slowly across southern.  Fengal could move over the Arabian Sea in 48 hours.

Tropical Cyclone Fengal will weaken gradually as it moves farther inland over southern India.  Fengal will continue to drop heavy rain on parts of Tamil Nadu during the next 24 hours.   Heavy rain is likely to cause floods in some locations.
