Tropical Cyclone Asani Intensifies to Equivalent of a Hurricane/Typhoon

Tropical Cyclone Asani intensified to the equivalent of a hurricane/typhoon over the Bay of Bengal on Sunday morning. At 5:00 a.m. EDT on Sunday the center of Tropical Cyclone Asani was located at latitude 12.0°N and longitude 88.3°E which put it about 750 miles (1215 km) south of Kolkata, India. Asani was moving toward the northwest at 10 m.p.h (16 km/h). The maximum sustained wind speed was 75 m.p.h. (120 km/h) and there were wind gusts to 90 m.p.h. (145 km/h). The minimum surface pressure was 977 mb.

Former Tropical Cyclone 02B intensified on Sunday morning and the India Meteorological Department designated the system as Tropical Cyclone Asani. The strongest thunderstorms were occurring in bands southwest of the center of Asani’s circulation. Other bands of showers and thunderstorms were revolving around the center of Tropical Cyclone Asani. Storms near the center of circulation generated upper level divergence that pumped mass away from the tropical cyclone. Winds to hurricane/typhoon force extended out 30 miles (50 km) from the center of Asani. Winds to tropical storm force extended out 140 miles (225 km) from the center of circulation.

Tropical Cyclone Asani will move through an environment favorable for intensification during the next 24 hours. Asani will move over water where the Sea Surface Temperatures are near 30˚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. Tropical Cyclone Asani is likely to intensify during the next 24 hours. Asani will move toward a mass of drier air when it moves closer to India in a day or two.

Tropical Cyclone Asani will move around the western side of a high pressure system over Southeast Asia. The high pressure system will steer Asani toward the northwest during the next 24 hours. On its anticipated track Tropical Cyclone Asani will move toward the east coast of India. Asani could be southeast of Visakhapatnam in 48 hours.

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.

Tropical Cyclone 05B Forms over Bay of Bengal

Tropical Cyclone 05B formed over the Bay of Bengal on Thursday night. At 10:00 p.m. EST on Thursday the center of Tropical Cyclone 05B was located at latitude 14.4°N and longitude 85.8°E which put it about 360 miles (580 km) southeast of Visakhapatnam, India. Tropical Cyclone 05B was moving toward the northwest at 16 m.p.h. (26 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 central Bay of Bengal strengthened on Thursday night into Tropical Cyclone 05B. The distribution of thunderstorms around Tropical Cyclone 05B was asymmetrical. The strongest thunderstorms were occurring in bands in the northern half of the tropical cyclone. Bands in the southern half of the circulation consisted primarily of showers and lower clouds. The thunderstorms in the northern half of the circulation generated upper level divergence that pumped mass away to the north of the tropical cyclone. The distribution of wind speeds was also asymmetrical. Winds to tropical storm force extended out 150 miles (240 km) in the northern half of the tropical cyclone. The winds in the southern half of the circulation were blowing at less than tropical storm force.

Tropical Cyclone 05B will move through an environment favorable for intensification during the next 24 hours. The tropical cyclone 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 produce southerly winds that will blow toward the top of the tropical cyclone. Those winds will cause some vertical wind shear, but the wind shear will not be strong enough to prevent intensification. Tropical Cyclone 05B is likely to intensify during the next 24 hours. The India Meteorological Department will likely give the tropical cyclone a name on Friday.

Tropical Cyclone 05B will move around the western end of a high pressure system over southeast Asia. The high pressure system will steer the tropical cyclone toward the northwest during the next 24 hours. On its anticipated track Tropical Cyclone 05B will approach the coast of India northeast of Visakhapatnam in 24 hours. It will bring gusty winds and locally heavy rain to the coastal parts of northeastern Andhra Pradesh and Orissa. Tropical Cyclone 05B will move more slowly after it nears the coast and it could turn toward the northeast during the weekend.

Tropical Cyclone 04B Brings Rain to Southern India

Tropical Cyclone 04B brought rain to parts of southern India on Thursday. At 4:00 a.m. EST on Thursday the center of Tropical Cyclone 04B was located at latitude 13.1°N and longitude 80.6°W which put it about 30 miles (50 km) east of Chennai, India. The tropical cyclone was moving toward the west-northwest at 9 m.p.h. (14 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 1003 mb.

A low pressure system over the western Bay of Bengal strengthened on Thursday morning and the Joint Typhoon Warning Center designated the system as Tropical Cyclone 04B. The India Meteorological Department classified the system as a depression. The center of Tropical Cyclone 04B was located near Chennai, India. The strongest thunderstorms were occurring in bands west of the center of circulation and along the northern periphery of the tropical cyclone. Bands in other parts of the circulation consisted primarily of showers and lower clouds. Winds to tropical storm force extended out 40 miles (65 km/h) from the center of the tropical cyclone.

The center of Tropical Cyclone 04B will make landfall on the southern coast of India near Chennai in a few hours. The tropical cyclone will bring gusty winds to the northern coast of Tamil Nadu and the southern coast of Andhra Pradesh. Tropical Cyclone 04B will drop locally heavy rain over parts or northern Tamil Nadu, southern Andhra Pradesh and southern Karnataka as it moves inland. The tropical cyclone will weaken gradually after it moves inland over southern India.

Tropical Cyclone Gulab Redevelops over the Arabian Sea

Tropical Cyclone Gulab redeveloped over the Arabian Sea on Thursday. At 5:00 p.m. EDT on Thursday the center of Tropical Cyclone Gulab was located at latitude 22.8°N and longitude 65.1°E which put it about 175 miles (280 km) south-southwest of Karachi, Pakistan. Gulab was moving toward the west at 15 m.p.h. (24 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 994 mb.

Tropical Cyclone Gulab redeveloped over the Arabian Sea south of Pakistan on Thursday. Gulab originally formed over the northern Bay of Bengal a few days ago. Gulab made landfall on the coast of India near Tekkali and then it moved westward across India. Even though Tropical Cyclone Gulab weakened after it made landfall, the circulation remained relatively intact because of a favorable upper level environment. There was not a lot of vertical wind shear. In fact, upper level divergence continued to pump away mass and allow the surface low pressure system to persist. The circulation began to intensify as Gulab approached the Arabian Sea and it strengthened once the low level center was back over water.

The circulation around Tropical Cyclone Gulab exhibited more organization on Thursday. More thunderstorms developed in bands revolving around the center of Gulab. The strongest thunderstorms were occurring in bands in the southern half of Tropical Cyclone Gulab. Bands in the northern half of the circulation consisted primarily of showers and lower clouds. The northern half of Gulab appeared to be pulling drier air from Asia into its circulation. Winds to tropical storm force extended out 140 miles (220 km) on the northern side of Tropical Cyclone Gulab. Winds to tropical storm force extended out 60 miles (95 km) on the southern side of the circulation.

Tropical Cyclone Gulab will move through an environment favorable for intensification during the next 36 hours. Gulab 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 Southwest Asia and the northern Arabian Sea. The upper level winds are weak near the middle of the ridge and there will be little vertical wind shear. Dry air from Asia could continue to limit the development of thunderstorms in the northern half of Gulab. Tropical Cyclone Gulab will intensify during the next 36 hours and it could strengthen to the equivalent of a hurricane/typhoon.

Tropical Cyclone Gulab will move around the southern side of a high pressure system over Southwest Asia. The high will steer Gulab toward the west during the next 36 hours. On its anticipated track Tropical Cyclone Gulab could approach the coast of Oman near Muscat in 60 hours.

Tropical Cyclone Gulab forms over Northern Bay of Bengal

Tropical Cyclone Gulab formed over the northern Bay of Bengal on Saturday. At 11:00 a.m. EDT on Saturday the center of Tropical Cyclone Gulab was located at latitude 18.3°N and longitude 88.0°W which put it about 245 miles (395 km) east of Tekkali, India. Gulab 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 997 mb.

The circulation around a low pressure system over the northern Bay of Bengal strengthened on Saturday and the India Meteorological Department designated the system as Tropical Cyclone Gulab. The distribution of thunderstorms around Tropical Cyclone Gulab was asymmetrical. The strongest thunderstorms were occurring in bands in the western half of Gulab’s circulation. Bands in the eastern half of the tropical cyclone consisted primarily of showers and lower clouds. An upper level ridge over southern Asia was producing northeasterly winds that were blowing toward the top of Tropical Cyclone Gulab. Those winds were causing moderate vertical wind shear and they were contributing to the asymmetrical distribution of thunderstorms. Winds to tropical storm force extended out 60 miles (96 km) from the center of Gulab.

Tropical Cyclone Gulab will move through an environment that is marginally favorable for intensification during the next 24 hours. Gulab will move over water where the Sea Surface Temperatures are near 29˚C. However, the upper level ridge over southern Asia will continue to cause moderate vertical wind shear. The wind shear will inhibit intensification. Tropical Cyclone Gulab could strengthen a little during the next 24 hours if the wind shear does not increase. If the upper level winds get stronger, then the wind shear will cause Gulab to weaken.

Tropical Cyclone Gulab will move south of a high pressure system over southern Asia. The high will steer Gulab toward the west during the next 24 hours. On its anticipated track Tropical Cyclone Gulab could approach the coast of Andhra Pradesh near Tekkali in 24 hours. Gulab will bring gusty winds and locally heavy rain to northeastern Andhra Pradesh and southern Odisha. Heavy rain could cause flash floods in some locations.

Tropical Cyclone Yaas Hits Northeast India

Tropical Cyclone Yaas hit northeastern India early on Wednesday. At 5:00 a.m. EDT on Wednesday the center of Tropical Cyclone Yaas was located at latitude 21.8°N and longitude 86.8°E which put it about 115 miles (185 km) southwest of Kolkata, India. Yaas was moving toward the northwest at 7 m.p.h. (11 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.

Tropical Cyclone Yaas made landfall on the coast of northeastern India early on Wednesday. The center of Yaas crossed the coastline near Balasore, India. Tropical Cyclone Yaas was the equivalent of a strong tropical storm at the time when it made landfall. Winds to tropical storm force extended out 160 miles (260 km) on the eastern side of Yaas over the northern Bay of Bengal. Winds to tropical storm force extended out 140 miles (225 km) on the western side of the circulation which was over northern Odisha.

Tropical Cyclone Yaas will move slowly toward the northwest over northeastern India during the next day or so. Yaas will weaken gradually as it moves farther inland. Tropical Cyclone Yaas will produce gusty winds over northern Odisha during the next 24 hours. The wind could cause sporadic power outages. Yaas will also drop locally heavy rain over parts of northeastern India and flash floods could occur in some locations. The heaviest rain will fall in the western side of the circulation. Tropical Cyclone Yaas may have caused a storm surge of up to 7 feet (2 meters) along the coast of northern Bay of Bengal. The water level should drop slowly as Yaas moves farther inland and weakens.
