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.

Tropical Cyclone Yaas Strengthens to Equivalent of Hurricane/Typhoon

Tropical Cyclone Yaas strengthened to the equivalent of a hurricane/typhoon over the northern Bay of Bengal on Tuesday. At 11:00 a.m. EDT on Tuesday the center of Tropical Cyclone Yaas was located at latitude 20.1°N and longitude 89.1°E which put it about 195 miles (310 km) south of Kolkata, India. Yaas was moving toward the north at 11 m.p.h. (17 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 972 mb.

Tropical Cyclone Yaas intensified to the equivalent of a hurricane/typhoon south of Kolkata on Tuesday. A broken ring of thunderstorms surrounded the center of Yaas and the strongest winds were occurring in the storms in the ring. Bands of showers and thunderstorms were revolving around the center of Tropical Cylone Yaas. Storms near the center of circulation generated upper level divergence that pumped mass away to the west and north of the tropical cyclone. Winds to hurricane/typhoon force extended out 30 miles (50 km) from the center of Yaas. Winds to tropical storm force extended out 160 miles (260 km) from the center of circulation.

Tropical Cyclone Yaas will move through an environment favorable for intensification during the next 12 hours . Yaas 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 centered over Bangladesh. The ridge will produce easterly winds which will blow toward the top of the tropical cyclone. Those winds will cause some vertical wind shear, but the shear may not be strong enough to prevent intensification. Tropical Cyclone Yaas could strengthen gradually during the next 12 hours.

Tropical Cyclone Yaas will move around the western side of a high pressure system over Southeast Asia. The high will steer the tropical cyclone toward the north-northwest during the next 36 hours. On its anticipated track Yaas will make landfall on the coastline of Odisha southwest of Kolkata in 15 hours. Tropical Cyclone Yaas will be the equivalent of a hurricane/typhoon when it approaches the coast. Yaas is likely to bring damaging winds and locally heavy rain to the coastal regions of Odisha and West Bengal. Heavy rain could cause flash floods over parts of northeastern India. The coast along the northern Bay of Bengal is very vulnerable to a storm surge. Tropical Cyclone Yaas will cause a dangerous storm surge of up to 9 feet (3 meters) on parts of the coast around the northern Bay of Bengal.

Tropical Cyclone Yaas Intensifies South of Kolkata

Tropical Cyclone Yaas intensified over the northern Bay of Bengal on Monday night. At 11:00 p.m. EDT on Monday the center of Tropical Cyclone Yaas was located at latitude 18.5°N and longitude 88.0°E which put it about 305 miles (495 km) south of Kolkata, India. Yaas was moving toward the north-northwest at 13 m.p.h. (20 km/h). The maximum sustained wind speed was 70 m.p.h. (110 km/h) and there were wind gusts to 85 m.p.h. (135 km/h). The minimum surface pressure was 975 mb.

Tropical Cyclone Yaas strengthened to almost the equivalent of a hurricane/typhoon south of Kokata on Monday night. The distribution of thunderstorms around Yaas remained asymmetrical. Most of the thunderstorms were occurring in bands in the western half of Tropical Cyclone Yaas. Bands in the eastern half of the circulation consisted primarily of showers and lower clouds. The inner end of a rainband wrapped around the western and southern sides of the center of Yaas. Storms near the center of circulation generated upper level divergence that pumped mass away to the west and north of the tropical cyclone. Winds to tropical storm force extended out 160 miles (260 km) from the center of circulation.

Tropical Cyclone Yaas will move through an environment favorable for intensification during the next 24 hours. Yaas will move over water where the Sea Surface Temperatures are near 30°C. It will move under the southwestern part of an upper level ridge over the Bay of Bengal. The ridge will produce easterly winds which will blow toward the top of the tropical cyclone. Those winds will cause some vertical wind shear, but the shear will not be enough to prevent intensification. Tropical Cyclone Yaas will strengthen to the equivalent of a hurricane/typhoon during the next 24 hours.

Tropical Cyclone Yaas will move around the western side of a high pressure system over Southeast Asia. The high will steer the tropical cyclone toward the north-northwest during the next 36 hours. On its anticipated track Yaas will make landfall on the coastline of Odisha southwest of Kolkata in 24 hours. Tropical Cyclone Yaas will be the equivalent of a hurricane/typhoon when it approaches the coast. Yaas is likely to bring damaging winds and locally heavy rain to the coastal regions of Odisha and West Bengal. Tropical Cyclone Yaas will cause a dangerous storm surge of up to 9 feet (3 meters) on parts of the coast around the northern Bay of Bengal.

Tropical Cyclone Forms over Bay of Bengal

A tropical cyclone formed over the Bay of Bengal on Sunday night. At 11:00 p.m. EDT on Sunday the center of a tropical cyclone was located at latitude 16.2°N and longitude 89.8°E which put it about 465 miles (750 km) south-southeast of Kolkata, India. The tropical cyclone was moving toward the northeast at 8 m.p.h. (13 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 993 mb.

A low pressure system over the Bay of Bengal strengthened on Sunday night and the system was designated as Tropical Cyclone 02B by the Joint Typhoon Warning Center. The circulation around the tropical cyclone was still organizing. Many of the thunderstorms were occurring in bands in the outer portion of the circulation around the tropical cyclone. The inner end of a rainband began to wrap around the western side of the center of circulation. The circulation around the tropical cyclone was large. Winds to tropical storm force extended out 175 miles (280 km) from the center of circulation.

The tropical cyclone will move through an environment favorable for intensification during the next 48 hours. It will move over water where the Sea Surface Temperatures are near 31°C. The tropical cyclone will move under the southern part of an upper level ridge over the Bay of Bengal. The ridge will produce easterly winds which will blow toward the top of the tropical cyclone. Those winds will cause some vertical wind shear, but the shear will not be enough to prevent intensification. The tropical cyclone will intensify during the next 24 hours. It could intensify more rapidly once an inner core with an eye and an eyewall form. The tropical cyclone could strengthen to the equivalent of a hurricane/typhoon within 36 hours.

The tropical cyclone will move around the western side of a high pressure system over Southeast Asia. The high will steer the tropical cyclone toward the north-northwest during the next 48 hours. On its anticipated track the tropical cyclone could approach the coastline of Odisha and West Bengal in 48 hours. It will likely be the equivalent of a hurricane/typhoon when it approaches the coast. The tropical cyclone is likely to bring damaging winds, and locally heavy rain. It will also likely cause a dangerous storm surge on parts of the coast around the northern Bay of Bengal.

Tropical Cyclone Amphan Makes Landfall Near Kolkata

The center of Tropical Cyclone Amphan made landfall on the north coast of the Bay of Bengal near Kolkata, India on Wednesday.  At 11:00 a.m. EDT on Wednesday the center of Tropical Cyclone Amphan was located at latitude 22.7°N and longitude 88.4°E which put it about 30 miles (50 km) south-southwest of Kolkata, India.  Amphan was moving toward the north-northeast at 19 m.p.h. (30 km/h).  The maximum sustained wind speed was 85 m.p.h. (135 km/h) and there were wind gusts to 105 m.p.h. (165 km/h).  The minimum surface pressure was 979 mb.

The center of Tropical Cyclone Amphan made landfall near Haldia, India which is a little to the south-southwest of Kolkata on Wednesday.  The maximum sustained wind speed in Amphan at the time of landfall was 100 m.p.h. (160 km/h).  Tropical Cyclone Amphan weakened after the center moved over land.  Winds to hurricane/typhoon force extended out 20 miles (30 km) from the center of circulation.  Winds to tropical storm force extended out 160 miles (260 km) to the southeast of the center.  The stronger winds were occurring near the center of circulation and over the northern Bay of Bengal.

When Tropical Cyclone Amphan approached the coast, the heaviest rain occurred in bands in the western side of Amphan.  Heavy rain fell over parts of northern Odisha and West Bengal.  After the center of Amphan made landfall and the tropical cyclone moved inland, the heaviest rain fell in bands in the northeastern part of the circulation.  Heavy rain was falling over parts of Bangladesh.

Strong southerly winds blowing toward the north coast of the Bay of Bengal pushed water toward Bangladesh and the coast of India south of Kolkata.  The coast around the northern Bay of Bengal is very vulnerable to storm surges caused by tropical cyclones.  Tropical Cyclone Amphan likely caused a significant storm surge along that coast.

Tropical Cyclone Amphan will move around the northwestern part of a high pressure system over Southeast Asia.  The high will steer Amphan toward the north-northeast.  On its anticipated track the center of Tropical Cyclone Amphan will move across western Bangladesh and northeastern India.  The circulation around Amphan will continue to weaken as the system moves farther inland.  Tropical Cyclone Amphan will continue to drop locally heavy rain over Bangladesh and northeastern India.  Heavy rain could cause flash floods to occur in some locations.

Powerful Tropical Cyclone Fani Makes Landfall in India

Powerful Tropical Cyclone Fani made landfall near Puri, India on Thursday night.  At 11:00 p.m. EDT on Thursday the center of Tropical Cyclone Fani was located at latitude 19.4°N and longitude 85.8°E which put it about 25 miles (40 km) south of Puri, India.  Fani was moving toward the north-northeast at 11 m.p.h. (17 km/h).  The maximum sustained wind speed was 150 m.p.h. (240 km/h) and there were wind gusts to 185 m.p.h. (295 km/h).  The minimum surface pressure was 922 mb.

Tropical Cyclone Fani is a large dangerous system.  Winds to hurricane/typhoon force extend out about 70 miles (110 km) from the center of circulation.  Winds to tropical storm force extend out about 225 miles (360 km) from the center over the Bay of Bengal.  The Hurricane Intensity Index (HII) for Tropical Cyclone Fani is 31.6.  The Hurricane Size Index (HSI) is 25.6 and the Hurricane Wind Intensity Size Index (HWISI) is 57.2.  Tropical Cyclone Fani has the potential to cause widespread significant damage.

Tropical Cyclone Fani will cause the greatest wind damage along the northeast coast of Odisha.  It could also produce a significant storm surge along the coast.  The surge will be highest in bays, estuaries and mouths of rivers.  Fani will drop heavy rain over northeast Odisha, West Bengal and portions of Bangladesh.  The heavy rain is likely to cause inland fresh water floods in some locations.  Wind and rain could cause damage around Kolkata (Calcutta), India.

An upper level trough over India will steer Tropical Cyclone Fani toward the northeast during the next 48 hours.  On its anticipated path Fani will pass near Bhubaneshwar, Cuttack and Baleshwar in Odisha.  Tropical Cyclone Fani could still be the equivalent of a hurricane/typhoon when it passes near those locations.  Fani will weaken steadily while it moves northeast.  It is likely to be the equivalent of a tropical storm when it passes near Kolkata.  Tropical Cyclone Fani will weaken to the equivalent of a tropical depression when it passes over Bangladesh, but it could still drop heavy rain around Dhaka.  Serious flooding could occur in Bangladesh while Fani weakens.

Dangerous Tropical Cyclone Fani Near Northeast India

Dangerous Tropical Cyclone Fani neared the coast of northeastern India on Thursday.  Fani rapidly intensified into the nearly the equivalent of a Category 5 hurricane on the Saffir-Simpson Scale.  At 11:00 a.m. EDT on Thursday the center of Tropical Cyclone Fani was located at latitude 18.0°N and longitude 84.9°E which put it about 100 miles (160 km) east of Visakhapatnam, India.  Fani was moving toward the north at 11 m.p.h. (17 km/h).  The maximum sustained wind speed was 155 m.p.h. (250 km/h) and there were wind gusts to 190 m.p.h. (305 km/h).  The minimum surface pressure was 918 mb.

Tropical Cyclone Fani intensified rapidly during recent hours.  A circular eye with a diameter of 20 miles (32 km) developed at the center of circulation.  A ring of strong thunderstorms surrounded the eye and the strongest winds were occurring in that ring of storms.  Bands of showers and thunderstorms were revolving around the core of Tropical Cyclone Fani.  Storms near the core were generating strong upper level divergence which was pumping mass away from the tropical cyclone.

The circulation around Tropical Cyclone Fani grew larger as it intensified.  Winds to hurricane/typhoon force extended out about 60 miles (95 km) from the center of circulation.  Winds to tropical storm force extended out about 185 miles (295 km) from the center.  The Hurricane Intensity Index (HII) for Tropical Cyclone Fani was 33.3.  The Hurricane Size Index (HSI) was 21.7 and the Hurricane Wind Intensity Size Index (HWISI) was 55.0.  Tropical Cyclone Fani was capable of causing widespread significant damage.

Tropical Cyclone Fani is moving around the western end of a subtropical ridge.  The ridge is steering Fani toward the north.  On its anticipated track Tropical Cyclone Fani is likely to make landfall near Brahmapur, India in about 12 hours.  An upper level trough over India will steer Fani toward the northeast after it makes landfall.  Tropical Cyclone Fani could pass near Puri, Bhubaneswar, Cuttack and Kolkata (Calcutta), India.

Tropical Cyclone Fani will remain in a favorable environment during the 12 hours prior to landfall.  Fani will be over water where the Sea Surface Temperature is near 30°C.  It will move through an environment where the upper level winds are weak and there will be little vertical wind shear.  Tropical Cyclone Fani will weaken after landfall.  The upper level trough over India will produce stronger southwesterly winds, which will increase the vertical wind shear after Fani makes landfall.  More wind shear and more friction over the land will cause Tropical Cyclone Fani to weaken to the equivalent of a tropical storm within 24 hours after landfall occurs.

Tropical Cyclone Fani is a dangerous tropical cyclone.  The strengthen and size of Fani will create the potential for widespread significant damage.  The counterclockwise circulation will cause the winds to blow water toward the coast along the northern Bay of Bengal.  Tropical Cyclone Fani could generate a storm surge of 15 to 20 feet (4.5 to 6.0 meters) in bays, estuaries and the mouths of rivers which act as funnels during storm surges.  Heavy rain could cause inland fresh water flooding in parts of northeastern India and Bangladesh.  The greatest threats are to the Indian states of Odisha (Orissa) and West Bengal.
