Tropical Cyclone Remal Brings Wind and Rain to West Bengal and Bangladesh

Tropical Cyclone Remal brought wind and rain to West Bengal and Bangladesh on Sunday. At 5:00 p.m. EDT on Sunday the center of Tropical Cyclone Remal was located at latitude 22.0°N and longitude 88.5°E which put it about 65 miles (105 km) south of Kolkata, India. Remal was moving toward the north at 9 m.p.h. (15 km/h). The maximum sustained wind speed was 65 m.p.h. (105 km/h) and there were wind gusts to 80 m.p.h. (130 km/h). The minimum surface pressure was 978 mb.

The center of Tropical Cyclone Remal made landfall on the coast of West Bengal south of Kolkata on Sunday. The circulation around Remal was large at the time of landfall. Winds to tropical storm force extended out 165 miles (265 km) from the center of Remal’s circulation. A weather station at Mongla, Bangladesh reported a sustained wind speed of 47 m.p.h. (76 km/h).

Tropical Cyclone Remal was moving along with the leading edge of a surge of humid air moving north in the monsoonal flow over the Bay of Bengal. The monsoonal flow will steer Remal toward the northeast during the next 24 hours. On its anticipated track Tropical Cyclone Remal will move inland across Bangladesh.

Tropical Cyclone Remal will weaken gradually as it moves farther inland. Remal will continue to bring strong winds and locally heavy rain to Bangladesh and adjacent parts West Bengal. Heavy rain is likely to cause floods in some locations. Remal could also cause a storm surge of up to 7 feet (2 meters) along the coast of Bangladesh. Weather conditions should start to improve gradually on Monday when Tropical Cyclone Remal moves farther inland and weakens.

Tropical Cyclone Remal Approaches Bangladesh

Tropical Cyclone Remal was approaching the coast of Bangladesh and West Bengal on Sunday morning. At 5:00 a.m. EDT on Sunday the center of Tropical Cyclone Remal was located at latitude 20.7°N and longitude 88.9°E which put it about 155 miles (250 km) south-southeast of Kolkata, India. Remal was moving toward the north at 11 m.p.h. (17 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 985 mb.

Tropical Cyclone Remal was strengthening as it approached the coast of Bangladesh and West Bengal on Sunday morning. Even though Remal was getting stronger, the distribution of thunderstorms was asymmetrical. Most of the thunderstorms were occurring in bands in the southern half of Remal’s circulation. Bands in the northern part of Tropical Cyclone Remal consisted primarily of showers and lower clouds. Storms near the center of Remal’s circulation generated upper level divergence that pumped mass away from the tropical cyclone. The removal of mass caused the surface pressure to decrease.

The circulation around Tropical Cyclone Remal was large. Winds to tropical storm force extended out 190 miles (305 km) from the center of Remal’s circulation.

Tropical Cyclone Remal will move through an environment favorable for intensification during the next 12 hours. Remal will move over water where the Sea Surface Temperatures are near 31°C. It will move under the axis of an upper level ridge over South Asia and the Bay of Bengal. The winds are weak near the axis off the ridge and there will be little vertical wind shear. Tropical Cyclone Remal is likely to intensify during the next 12 hours. The large circulation around Remal could cause intensification to occur slowly.

Tropical Cyclone Remal formed along the leading edge of a surge of humid air moving north in the monsoonal flow over the Bay of Bengal. The monsoonal flow will continue to steer Remal north during the next 12 hours. On its anticipated track Tropical Cyclone Remal will reach the northern coast of the Bay of Bengal in 12 hours. The center of Remal is likely to make landfall near the western border between India and Bangladesh.

Tropical Cyclone Remal will bring strong winds and locally heavy rain to Bangladesh and adjacent parts West Bengal. Heavy rain is likely to cause floods in some locations. Remal could also cause a storm surge of up to 7 feet (2 meters) along the coast of Bangladesh.

Low Pressure System Forms over Bay of Bengal

A low pressure system formed over the Bay of Bengal on Thursday. The low pressure system was designated as Invest 95B. At 10:00 p.m. EST on Thursday the center of a low pressure system was located at latitude 9.4°N and longitude 86.3°E which put it about 485 miles (780 km) southeast of Chennai, India. The low pressure system was moving toward the northwest at 10 m.p.h. (16 km/h). The maximum sustained wind speed was 25 m.p.h. (40 km/h) and there were wind gusts to 35 m.p.h. (55 km/h). The minimum surface pressure was 1008 mb.

The circulation around a low pressure system over the Bay of Bengal exhibited more organization on Thursday evening. The pattern of clouds began to look more like a developing tropical cyclone. More thunderstorms formed in bands around the low pressure system. The bands started to revolve around the center of circulation. Storms near the center began to generate upper level divergence that pumped mass away from the low pressure system.

The low pressure system will be in an environment favorable for the development of a tropical cyclone during the next 36 hours. Invest 95B will move over water where the Sea Surface Temperatures are near 29°C. It will move under the middle of an upper level ridge over the Bay of Bengal. The upper level winds are weak near the middle of the ridge and there will be little vertical wind shear. The low pressure system will intensify during the next 36 hours. It is likely to develop into a tropical cyclone.

The low pressure system will move around the southwestern part of a high pressure system over East Asia. The high pressure system will steer Invest 95B toward the northwest during the next 36 hours. On its anticipated track, the low pressure system will move toward the coast of southeast India. It could approach the coast as a tropical cyclone by the end of the weekend.

Tropical Cyclone Hamoon Forms over Northern Bay of Bengal

Tropical Cyclone Hamoon formed over the northern Bay of Bengal on Monday morning. At 11:00 a.m. EDT on Monday the center of Tropical Cyclone Hamoon was located at latitude 18.7°N and longitude 87.6°E which put it about 390 miles (630 km) southwest of Chittagong, Bangladesh. Hamoon was moving toward the north-northeast at 12 m.p.h. (19 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 1000 mb.

A low pressure system over the northern Bay of Bengal intensified on Monday morning and the India Meteorological Department designated the system as Tropical Cyclone Hamoon. The inner end of a rainband wrapped around the center of Hamoon’s circulation. Thunderstorms were occurring in bands in the northern half of Tropical Cyclone Hamoon. Bands in the southern half of Hamoon’s circulation consisted primarily of showers and lower clouds. Storms near the center of circulation generated upper level divergence that pumped mass away to the northeast of the tropical cyclone.

Winds to tropical storm force extended out 175 miles (280 km) in the northern side of Tropical Cyclone Hamoon. Winds to tropical storm force extended out 90 miles (145 km) in the southern part of Hamoon’s circulation.

Tropical Cyclone Hamoon will move through an environment somewhat favorable for intensification during the next 24 hours. Hamoon will move over water where the Sea Surface Temperatures are near 29°C. It will move under the eastern side of an upper level trough over India. The upper level trough will produce southwesterly winds that will blow toward the top of Hamoon’s circulation. Those winds will cause moderate vertical wind shear. The wind shear will inhibit intensification, but the shear may not be strong enough to prevent some intensification. Tropical Cyclone Hamoon could intensify during the next 24 hours.

The upper level trough over India will steer Tropical Cyclone Hamoon toward the northeast during the next 24 hours. On its anticipated track, Tropical Cyclone Hamoon will move toward Bangladesh. Hamoon will bring gusty winds and locally heavy rain to Bangladesh later this week. Heavy rain could cause flash floods in some locations.

Tropical Cyclone Forming over Bay of Bengal

A tropical cyclone was forming over the Bay of Bengal on Tuesday morning. At 11:00 a.m. EDT on Tuesday the center of a low pressure system was located at latitude 8.3°N and longitude 88.3°E which put it about 370 miles (595 km) southwest of Port Blair. The low pressure system was moving toward the northwest at 10 m.p.h. (16 km/h). The maximum sustained wind speed was 35 m.p.h. (55 km/h) and there were wind gusts to 45 m.p.h. (75 km/h). The minimum surface pressure was 998 mb.

A low pressure system was strengthening over the southern Bay of Bengal on Tuesday morning. The India Meteorological Department classified the system as a well marked low pressure system and the Joint Typhoon Warning Center designated the system as Invest 91B. The circulation around the low pressure system exhibited more organization on Tuesday morning. Several bands of showers and thunderstorms were beginning to revolve around the center of circulation. The strongest bands were in the southern and western parts of the low pressure system. Storms near the center of circulation began to generate upper level divergence that pumped mass away from the low pressure system. The removal of mass was causing the surface pressure to decrease.

The low pressure system will move through an environment favorable for intensification during the next few days. The low pressure system will move over water where the Sea Surface Temperatures are near 30˚C. It will move under the center of an upper level ridge over the Bay of Bengal. The upper level winds are weak near the center of the ridge and there will be little vertical wind shear. The low pressure system will intensify during the next 48 hours. It is likely to strengthen to a tropical cyclone during the next 24 hours. The low pressure system is likely to intensify to the equivalent of a hurricane/typhoon later this week.

The low pressure system will move around the western end of a high pressure system that extends from the Western North Pacific Ocean to Southeast Asia. The high pressure system will steer the low pressure system toward the north during the next 24 hours. On its anticipated track the center of circulation will pass west of the Andaman Islands and the Nicobar Islands. Bands of showers and thunderstorms in the eastern side of the circulation will bring gusty winds and locally heavy rain to the Andaman Islands and the Nicobar Islands. The low pressure system will move toward the north-northeast later this week. It is likely to make landfall near the border between Bangladesh and Myanmar in a few days. The low pressure system is likely to be the equivalent of a hurricane/typhoon when it makes landfall.

Low Pressure System Forms over Eastern Bay of Bengal

A low pressure system formed over the eastern Bay of Bengal near the Nicobar Islands on Friday morning. At 8:00 a.m. EDT on Friday the center of a low pressure system was located at latitude 8.6°N and longitude 92.5°E which put it about 45 miles (75 km) south-southwest of Malacca, Nicobar Islands and about 205 miles (330 km) south of Port Blair, Andaman Islands. The low pressure system was moving toward the northwest at 9 m.p.h (15 km/h). The maximum sustained wind speed was 30 m.p.h. (50 km/h) and there were wind gusts to 40 m.p.h. (65 km/h). The minimum surface pressure was 1001 mb.

A surface low pressure system, also designated as Invest 92B, formed over the eastern Bay of Bengal near the Nicobar Islands on Friday morning. The circulation around the low pressure system exhibited more organization on conventional and microwave satellite images. The strongest thunderstorms were occurring in a band just to the west of the center of the low pressure system. Other bands of showers and thunderstorms were revolving around the center of circulation. Storms near the center were generating upper level divergence that was pumping mass away from the low pressure system. The removal of mass was causing the surface pressure to decrease.

The low pressure system will move through an environment favorable for intensification during the next 24 hours. The low pressure system will move over water where the Sea Surface Temperatures are near 31˚C. It will move under the southern 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 the low pressure system. Those winds will cause some vertical wind shear, but the shear will not be large enough to prevent intensification. The low pressure system will strengthen during the next 24 hours and it could intensify to a tropical cyclone during the weekend.

The low pressure system will move around the southwestern side of a high pressure system over Southeast Asia. The high pressure system will steer the low pressure system toward the northwest during the next 24 hours. On its anticipated track the low pressure system will move slowly away from the Nicobar Islands. The low pressure system will drop locally heavy rain over the Nicobar Islands and the Andaman Islands. Heavy rain could cause flash floods in some locations.

Tropical Cyclone 01B Weakens over Bay of Bengal

Tropical Cyclone 01B weakened over the Bay of Bengal on Saturday. At 4:00 p.m. EST on Saturday the center of Tropical Cyclone 01B was located at latitude 11.2°N and longitude 82.8°E which put it about 160 miles (260 km) east-southeast of Chennai India. It was moving toward the west at 4 m.p.h (6 km/h). The maximum sustained wind speed was 35 m.p.h. (55 km/h) and there were wind gusts to 45 m.p.h. (75 km/h). The minimum surface pressure was 1003 mb.

Tropical Cyclone 01B weakened over the southwest Bay of Bengal on Saturday. The inflow around the western side of the tropical cyclone pulled drier air that was over India into Tropical Cyclone 01B. The drier air circulated around the tropical cyclone and it caused many of the thunderstorms to dissipate. A few thunderstorms persisted in a band northeast of the center of circulation. The other bands consisted primarily of showers and lower clouds. The dissipation of thunderstorms resulted in a circulation that was present only in the lower atmosphere.

Tropical Cyclone 01B will move through an environment unfavorable for intensification during the next 24 hours. The tropical cyclone will move over water where the Sea Surface Temperatures are near 28˚C. However the drier air will continue to inhibit the formation of new thunderstorms. The tropical cyclone will move under the western part of an upper level ridge centered over southeast Asia. The ridge will produce southeast winds that will blow toward the top of the depression. Those winds will cause moderate vertical wind shear and the shear will also inhibit intensification. Tropical Cyclone 01B is likely to continue to weaken as the circulation spins down. It could bring rain showers to southern India early next week.

Depression Forms over Bay of Bengal

A depression formed over the Bay of Bengal on Friday morning. At 10:00 a.m. EST on Friday the center of the depression was located at latitude 9.4°N and longitude 83.4°E which put it about 320 miles (515 km) southeast of Chennai India. It was moving toward the north-northwest at 7 m.p.h (11 km/h). The maximum sustained wind speed was 35 m.p.h. (55 km/h) and there were wind gusts to 45 m.p.h. (75 km/h). The minimum surface pressure was 1000 mb.

The circulation around a low pressure system over the Bay of Bengal strengthened on Friday morning and the system was classified as a depression by the India Meteorological Department. More thunderstorms develop near the enter of the depression. Bands of showers and thunderstorms were revolving around the center of circulation. Storms near the center generated upper level divergence that pumped mass away to the north of the depression.

The depression will move through an environment somewhat favorable for intensification during the next 24 hours. The depression will move over water where the Sea Surface Temperatures are near 28˚C. It will move under the western part of an upper level ridge centered over southeast Asia. The ridge will produce southeast winds that will blow toward the top of the depression. Those winds will cause moderate vertical wind shear and the shear will inhibit intensification. The depression is likely to intensify during the next 24 hours unless the upper level winds get stronger.

The depression will move south of a high pressure system centered over southeast Asia. The high pressure system will steer the depression slowly toward the northwest during the next 24 hours. On its anticipated track the depression will remain northeast of Sri Lanka and it will move closer to southern India.

Tropical Cyclone Jawad Spins over Bay of Bengal

Tropical Cyclone Jawad was spinning over the Bay of Bengal east of India on Friday night. At 10:00 p.m. EST on Friday the center of Tropical Cyclone Jawad was located at latitude 16.0°N and longitude 85.0°E which put it about 150 miles (240 km) southeast of Visakhapatnam, India. Jawad was moving toward the north at 10 m.p.h. (16 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 1000 mb.

Tropical Cyclone Jawad continued to spin over the Bay of Bengal east of India on Friday night. An upper level ridge over the Bay of Bengal was producing southeasterly winds that were blowing toward the top of Jawad’s circulation. Those winds were causing moderate vertical wind shear and the shear was keeping Tropical Cyclone Jawad from getting stronger. The strongest thunderstorms in Jawad were occurring in the northern half of the circulation because of the vertical wind shear. Bands in the southern half of the circulation consisted primarily of showers and lower clouds. Winds to tropical storm force extended out 100 miles (160 km) from the center of Tropical Cyclone Jawad.

Tropical Cyclone Jawad will move through an environment only marginally favorable for intensification during the next 24 hours. Jawad will move over water where the Sea Surface Temperatures are near 28˚C. It will move under the western end of an upper level ridge over the Bay of Bengal. The ridge will continue to produce southerly winds that will blow toward the top of Jawad’s circulation. Those winds will cause moderate vertical wind shear. The wind shear is likely to remain strong enough to prevent Tropical Cyclone Jawad from strengthening during the next 24 hours.

Tropical Cyclone Jawad will move around the western end of a high pressure system over southeast Asia. The high pressure system will steer Jawad toward the north-northeast during the next several days. On its anticipated track Tropical Cyclone Jawad will move parallel to the east coast of India during the next 36 hours. Jawad could approach Kolkata in 72 hours. Tropical Cyclone Jawad could bring gusty winds and locally heavy rain to the coastal parts of northeastern Andhra Pradesh, Odisha, and West Bengal.
