Tropical Cyclone Senyar Brings Wind and Rain to Northern Sumatra

Leave a reply

Tropical Cyclone Senyar brought wind and rain to northern Sumatra on Wednesday.  At 4:00 a.m. EST on Wednesday the center of Tropical Cyclone Senyar was located at latitude 3.8°N and longitude 98.3°E which put the center about 30 miles (50 km) northwest of Medan, Indonesia.  Senyar was moving toward the south-southeast at 4 m.p.h. (6 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 999 mb.

Tropical Cyclone Senyar was located at latitude 3.8°N which once again proves that tropical cyclones can occur near the Equator.

Tropical Cyclone Senyar continued to be in an environment characterized by strong vertical wind shear.  An upper level ridge over the Western North Pacific Ocean was causing strong easterly winds that were blowing toward the top of Senyar’s circulation.  Those winds were causing strong vertical wind shear.  The strong winds were causing the distribution of thunderstorms in Tropical Cyclone Senyar to be asymmetrical.  Thunderstorms were occurring in bands in the western side of Senyar’s circulation.  Bands in the eastern side of Tropical Cyclone Senyar consisted primarily of showers and lower clouds.

he circulation around Tropical Cyclone Senyar was small.  Winds to tropical storm force extended out 60 miles (95 km) from the center of Senyar’s circulation.

Tropical Cyclone Senyar will move through an environment that will be marginally favorable for intensification during the next 24 hours.  Senyar will move over water where the Sea Surface Temperatures are near 29°C.  However, the upper level ridge over the Western North Pacific Ocean will continue to cause strong vertical wind shear.  The strong vertical wind shear will seriously inhibit intensification, but the shear may not be enough to prevent some intensification.  In addition, the center of Senyar’s circulation will be near the coast of northeastern Sumatra.  Tropical Cyclone Senyar could maintain its intensity during the next 24 hours.

Tropical Cyclone Senyar will move through along trough of low pressure that is near the Equator. The trough of low pressure will steer Senyar toward the southeast during the next 24 hours.  On its anticipated track, Tropical Cyclone Senyar will move along the northeastern coast of Sumatra during the next 24 hours.

Tropical Cyclone Senyar will continue to bring strong winds and heavy rain to Aceh province in northern Sumatra.  Heavy rain is likely to cause floods in some locations.  There are already reports of flooding and casualties in northern Sumatra.

Tropical Cyclone 04B formed over the Malacca Strait on Tuesday.  At 10:00 a.m. EST on Tuesday the center of Tropical Cyclone 04B was located at latitude 4.8°N and longitude 98.6°E which put the center about 35 miles (55 km) east-northeast of Langsa, Indonesia.  Tropical Cyclone 04B was moving toward the west-northwest at 4 m.p.h. (6 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 999 mb.

A low pressure system over the Malacca Strait strengthened on Tuesday and the U.S. Joint Typhoon Warning Center designated the system as Tropical Cyclone 04B.  The India Meteorological Department was classifying Tropical Cyclone 04B as a Depression.  It could be the first Tropical Cyclone observed to form over the Malacca Strait in the modern era.

Tropical Cyclone 04B formed in an environment characterized by strong vertical wind shear.  An upper level ridge over the Western North Pacific Ocean was causing strong easterly winds that were blowing toward the top of the tropical cyclone.  Those winds were causing strong vertical wind shear.  The strong winds were causing the distribution of thunderstorms in Tropical Cyclone 04B to be asymmetrical.  Thunderstorms were occurring in bands in the western side of the tropical cyclone.  Bands in the eastern side of Tropical Cyclone 04B consisted primarily of showers and lower clouds.

The circulation around Tropical Cyclone 04B was small.  Winds to tropical storm force extended out 60 miles (95 km) from the center of circulation.

Tropical Cyclone 04B will move through an environment that will be marginally favorable for intensification during the next 12 hours.  Tropical Cyclone 04B will move over water where the Sea Surface Temperatures are near 29°C.  However, the upper level ridge over the Western North Pacific Ocean will continue to cause strong vertical wind shear.  The strong vertical wind shear will seriously inhibit intensification, but the shear may not be enough to prevent some  intensification.  Tropical Cyclone 04B could intensity a little during the next 12 hours.

Tropical Cyclone 04B will move around the southwestern end of a high pressure system that is over the Western North Pacific Ocean and Southeast Asia.  The high pressure system will steer the tropical cyclone toward the west-northwest during the next 24 hours.  On its anticipated track, Tropical Cyclone 04B will make landfall in northern Sumatra near Idi in 12 hours.

Tropical Cyclone 04B will bring strong winds and heavy rain to Aceh province in northern Sumatra.  Heavy rain is likely to cause flash floods in some locations.

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.

Tropical Cyclone Fengal Brings Wind and Rain to Southeastern India

Tropical Cyclone Fengal brought wind and rain to southeastern India on Saturday.  At 10:00 a.m. EST on Saturday the center of Tropical Cyclone Fengal was located at latitude 12.4°N and longitude 80.5°E which put the center about 45 miles (75 km) south of Chennai, India.  Fengal was moving toward the west at 5 m.p.h. (8 km/h).  The maximum sustained wind speed was 50 m.p.h. (80 km/h) and there were wind gusts to 65 m.p.h. (105 km/h).  The minimum surface pressure was 989 mb.

The center of Tropical Cyclone Fengal made landfall on the coast of southeastern India between Chennai and Puducherry on Saturday.  Fengal was the equivalent of a tropical storm at the time of landfall.  Winds to tropical storm force extended out 70 miles (110 km) from the center of Tropical Cyclone Fengal.

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 24 hours.  On its anticipated track, Tropical Cyclone Fengal will move across southern India during the next 24 hours.

Tropical Cyclone Fengal will bring strong winds and heavy rain to Tamil Nadu.  Heavy rain is likely to cause floods in some locations.  Fengal could also cause a storm surge of up to 4 feet (1 meter) along the coast of Tamil Nadu.

Tropical Cyclone Fengal Forms Over Southwestern Bay of Bengal

Tropical Cyclone Fengal formed over the southwestern Bay of Bengal on Friday.  At 4:00 a.m. EST on Friday the center of Tropical Cyclone Fengal was located at latitude 11.2°N and longitude 82.2°E which put the center about 165 miles (270 km) east-southeast of the Puducherry, India. Fengal was moving toward the north-northwest 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 966 mb.

A low pressure system over the southwestern Bay of Bengal strengthened during Thursday night and the India Meteorological Department designated the system as Tropical Cyclone Fengal.  Thunderstorms formed near the center of Tropical Cyclone Fengal.  More thunderstorms also formed in bands revolving around the center of Fengal’s circulation.  Storms near the center of Fengal generated upper level divergence that pumped mass away from the tropical cyclone.  The removal of mass caused the surface pressure to decrease.

Tropical Cyclone Fengal will move through an environment favorable for intensification during the next 24 hours.  Fengal will move over water where where the Sea Surface Temperatures are near 29°C.  It will move under the axis of an upper level ridge that extends from India across the southern Bay of Bengal.  The upper level winds are weak near the axis of the ridge and there will be little vertical wind shear.  Tropical Cyclone Fengal is likely to intensify during the next 24 hours.

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-northwest during the next 24 hours.  On its anticipated track, Tropical Cyclone Fengal will approach the coast of southeastern India near Puducherry in 24 hours.

Tropical Cyclone Fengal will bring strong winds and heavy rain to Tamil Nadu.  Heavy rain is likely to cause floods in some locations.  Fengal could also cause a storm surge of up to 4 feet (1 meter) along the coast of Tamil Nadu.

Tropical Cyclone 04B Makes Landfall South-southwest of Kolkata

Tropical Cyclone 04B made landfall on the coast of India south-southwest of Kolkata on Friday. At 11:00 a.m. EDT on Friday the center of Tropical Cyclone 04B was located at latitude 21.9°N and longitude 87.7°E which put it about 65 miles (105 km) south-southwest of Kolkata India. The tropical cyclone was moving toward the west-northwest at 9 m.p.h. (15 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 990 mb.

Tropical Cyclone 04B strengthened during the hours prior to landfall. The maximum sustained wind speed was 50 m.p.h. (80 km/h) when Tropical Cyclone 04B made landfall on the coast of India south-southwest of Kolkata. Winds to tropical storm force extended out 85 miles (135 km) from the center of Tropical Cyclone 04B. Bands of showers and thunderstorms were revolving around a broad center of circulation.

Tropical Cyclone 04B will move south of a high pressure system over southern Asia. The high pressure system will steer the tropical cyclone toward the west-northwest during the next 48 hours. On its anticipated track Tropical Cyclone 04B will move farther inland over central India during the weekend. The tropical cyclone will gradually weaken when it moves farther inland. Tropical Cyclone 04B will drop heavy rain over parts of central India. Heavy rain could cause flash floods in some locations.

Tropical Cyclone 04B Forms over Northern Bay of Bengal

Tropical Cyclone 04B formed over the northern Bay of Bengal on Thursday afternoon. At 5:00 p.m. EDT on Thursday the center of Tropical Cyclone 04B was located at latitude 20.7°N and longitude 89.5°E which put it about 175 miles (280 km) southeast of Kolkata India. The tropical cyclone was moving toward the west-northwest at 9 m.p.h. (15 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 992 mb.

Tropical Cyclone 04B developed over the northern Bay of Bengal southeast of Koklata, India on Thursday afternoon. The distribution of thunderstorms around the tropical cyclone was asymmetrical. The strongest thunderstorms were occurring in bands in the southern and western parts of the circulation. Bands in the northern and eastern parts of Tropical Cyclone 04B consisted primarily of showers and lower clouds. An upper level ridge over southern Asia was producing easterly winds that were blowing toward the top of the tropical cyclone’s circulation. Those winds were causing moderate vertical wind shear and the wind shear was contribution to the asymmetrical distribution of thunderstorms. Winds to tropical storm force extended out 40 miles (65 km) from the center of Tropical Cyclone 04B.

Tropical Cyclone 04B will move through an environment somewhat favorable for intensification during the next 12 hours. The tropical cyclone 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 04B could intensify during the next 12 hours, if the upper level winds do not get any stronger.

Tropical Cyclone 04B will move south of a high pressure system over southern Asia. The high pressure system will steer the tropical cyclone toward the west-northwest during the next 24 hours. On its anticipated track the center of Tropical Cyclone 04B could be south of Kolkata in 12 hours. It could make landfall on the coast of India southwest of Kolkata in 18 hours. Tropical Cyclone 04B will bring gusty winds and locally heavy rain to the region of India south and west of Kolkata. Heavy rain could cause flash floods in some locations.

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 Nivar Moves along Andhra Pradesh Coast

Tropical Cyclone Nivar moved northward along the coast of Andhra Pradesh on Thursday. At 10:00 p.m. EST on Thursday the center of Tropical Cyclone Nivar was located at latitude 14.0°N and longitude 80.7°E which put it about 50 miles (80 km) south-southeast of Nellore, India. Nivar was moving toward the north 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 1003 mb.

After making landfall on the southeast coast of India near Puducherry on Wednesday, vertical wind shear blew the upper portion of Tropical Cyclone Nivar west of the surface circulation. An upper level ridge over India produced easterly winds which blew toward the top of Tropical Cyclone Nivar. Those winds caused strong vertical wind shear. The shear was strong enough to blow the upper part of Nivar west of the surface circulation. The upper part of the circulation moved westward across southern India and weakened. The surface circulation moved northward along the southeast coast of India and back over the Bay of Bengal north of Chennai.

Tropical Cyclone Nivar will move through an environment that will be only slightly favorable for intensification during the next few hours. Nivar will move over water where the Sea Surface Temperature is near 29°C, while it is over the Bay of Bengal. However, the upper level ridge will continue to cause strong vertical wind shear. The shear is likely to prevent Tropical Cyclone Nivar from strengthening.

Tropical Cyclone Nivar will continue to move north along the southeast coast of India for the next few hours. After that time a high pressure system over northern India will turn Nivar toward the west. On its anticipated track Tropical Cyclone Nivar is forecast to move inland over southern Andhra Pradesh and to move toward Karnataka. Nivar will weaken after the low level circulation moves inland, but it will drop locally heavy rain over southern Andhra Pradesh and Karnataka. Flash floods could occur in some locations.

Tropical Cyclone Nivar Makes Landfall in Tamil Nadu

Tropical Cyclone Nivar made landfall on the coast of Tamil Nadu on Wednesday. At 4:00 p.m. EST on Wednesday the center of Tropical Cyclone Nivar was located at latitude 12.2°N and longitude 79.8°E which put it about 25 miles (40 km) north of Puducherry, India. Nivar was moving toward the west-northwest at 12 m.p.h. (19 km/h). The maximum sustained wind speed was 80 m.p.h. (130 km/h) and there were wind gusts to 100 m.p.h. (160 km/h). The minimum surface pressure was 976 mb.

Tropical Cyclone Nivar made landfall on the southeast coast of India north of Puducherry on Wednesday. Nivar strengthened into the equivalent of a hurricane/typhoon over the Bay of Bengal before it made landfall. Winds to hurricane/typhoon force extended out 35 miles (55 km/h) from the center of Tropical Cyclone Nivar. Winds to tropical storm force extended out 150 miles (240 km) from the center of circulation.

Tropical Cyclone Nivar will produce gusty winds along the coast of Tamil Nadu between Cuddalore and Chennai. Winds blowing water toward the coast could cause a storm surge of up to six feet (two meters) between Puducherry and Chennai. Nivar will drop heavy rain over parts of northern Tamil Nadu and flash floods could occur in some locations.

Tropical Cyclone Nivar will move south of a high pressure system over India and the Bay of Bengal. The high will steer Nivar toward the west-northwest. The wind speed will steadily decrease when Tropical Cyclone Nivar moves inland. Nivar will drop locally heavy rain over parts of southern Andhra Pradesh and Karnataka when it moves farther inland over southern India.
