Tropical Cyclone Tej Makes Landfall in Eastern Yemen

Tropical Cyclone Tej made landfall in eastern Yemen on Monday afternoon. At 5:00 p.m. EDT on Monday the center of Tropical Cyclone Tej was located at latitude 15.6°N and longitude 52.0°E which put it about 25 miles (400 km) southwest of Nishtun, Yemen. Tej was moving toward the northwest at 5 m.p.h. (8 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 986 mb.

Tropical Cyclone Tej made landfall on the coast of eastern Yemen between Nishtun and Qishn on Monday afternoon. Tej weakened as it approached the coast of Yemen. Winds to hurricane/typhoon force extended out 35 miles (55 km) from the center of Tej’s circulation. Winds to tropical storm force extended out 90 miles (145 km) from the center of circulation.

The Hurricane Intensity Index (HII) for Tropical Cyclone Tej was 11.5. The Hurricane Size Index (HSI) was 11.5 and the Hurricane Wind Intensity Size Index (HWISI) was 23.0. Tropical Cyclone Tej was similar in size and intensity to Hurricane Dolly when Dolly hit south Texas in 2008.

Tropical Cyclone Tej was capable of causing regional minor damage. Tej will produce strong winds and locally heavy rain over eastern Yemen and far western Oman. Heavy rain is likely to cause flash floods in some locations.

Tropical Cyclone Tej will weaken steadily when it moves into the dry environment over eastern Yemen.

Tropical Cyclone Tej Moves Toward Eastern Yemen

Tropical Cyclone Tej moved over the Arabian Sea toward eastern Yemen on Sunday. At 11:00 a.m. EDT on Sunday the center of Tropical Cyclone Tej was located at latitude 13.6°N and longitude 54.0°E which put it about 255 miles (410 km) south of Salalah, Oman. Tej was moving toward the northwest at 10 m.p.h. (16 km/h). The maximum sustained wind speed was 115 m.p.h. (185 km/h) and there were wind gusts to 145 m.p.h. (235 km/h). The minimum surface pressure was 961 mb.

Tropical Cyclone Tej appeared to go through an eyewall replacement cyclone on Sunday. The inner end of a rainband wrapped around the original small eye and eyewall. The inner eyewall dissipated on Sunday afternoon and a larger eye was apparent on satellite images. The new, larger eye was surrounded by a ring of thunderstorms and the strongest winds were occurring in that ring of storms. Bands of showers and thunderstorms were revolving around the center of Tropical Cyclone Tej. Storms near the center generated upper level divergence that pumped mass away from the tropical cyclone.

Even though Tropical Cyclone Tej went through an eyewall replacement cycle, its circulation was still small. Winds to hurricane/typhoon force extended out 20 miles (30 km) from the center of Tej’s circulation. Winds to tropical storm force extended out 90 miles (145 km) from the center of circulation. The Hurricane Intensity Index (HII) for Tropical Cyclone Tej was 20.6. The Hurricane Size Index (HSI) was 8.7 and the Hurricane Wind Intensity Size Index (HWISI) was 29.3. Tropical Cyclone Tej was similar in size and intensity to Hurricane Zeta when Zeta hit Louisiana in 2020.

Tropical Cyclone Tej will move through an environment that will become more unfavorable for intensification during the next 24 hours. Tej will move over water where the Sea Surface Temperatures are near 29°C. It will move through a region where the upper level winds are weak and there will be little vertical wind shear. However, Tropical Cyclone Tej will move closer to dry air over Yemen and Oman. Northerly winds in the western side of Tej’s circulation could start to pull the dry air into the tropical cyclone. The recently completed eyewall replacement cycle and the dry air could cause Tropical Cyclone Tej to weaken during the next 24 hours.

Tropical Cyclone Tej will move around the southwestern part of a high pressure system over South Asia. The high pressure system will steer Tej toward the northwest during the next 24 hours. On its anticipated track, Tropical Cyclone Tej will approach the coast of eastern Yemen near Nishtun in 24 hours. Tej will bring strong winds to eastern Yemen. Tropical Cyclone Tej will also drop heavy rain on parts of eastern Yemen and western Oman. Heavy rain could cause flash floods in some locations.

Tropical Cyclone Tej Rapidly Intensifies to Equivalent of a Major Hurricane

Tropical Cyclone Tej rapidly intensified to the equivalent of a major hurricane over the Arabian Sea east-southeast of Socotra on Saturday. At 5:00 p.m. EDT on Saturday the center of Tropical Cyclone Tej was located at latitude 11.7°N and longitude 56.3°E which put it about 175 miles (280 km) east-southeast of Socotra. Tej was moving toward the northwest at 13 m.p.h. (21 km/h). The maximum sustained wind speed was 120 m.p.h. (195 km/h) and there were wind gusts to 140 m.p.h. (220 km/h). The minimum surface pressure was 958 mb.

Tropical Cyclone Tej rapidly intensified to the equivalent of a major hurricane over the Arabian Sea on Saturday. A small circular eye with a diameter of 10 miles (16 km) formed at the center of Tej’s circulation. The eye was surrounded by a ring of thunderstorms and the strongest winds were occurring in that ring of storms. Bands of showers and thunderstorms were revolving around the center of circulation. Storms near the center generated strong upper level divergence that pumped large amounts of mass away from the tropical cyclone. The removal of large amounts of mass caused the surface pressure to decrease rapidly.

The circulation around Tropical Cyclone Tej was small. Winds to hurricane/typhoon force extended out 15 miles (25 km) from the center of Tej’s circulation. Winds to tropical storm force extended out 100 miles (160 km) from the center of circulation. The Hurricane Intensity Index (HII) for Tropical Cyclone Tej was 22.1. The Hurricane Size Index (HSI) was 6.0 and the Hurricane Wind Intensity Size Index (HWISI) was 28.1. Tropical Cyclone Tej was capable of causing localized major damage.

Tropical Cyclone Tej will move through an environment very favorable for intensification during the next 24 hours. Tej will move over water where the Sea Surface Temperatures are near 29°C. It will move through a region where the upper level winds are weak and there will be little vertical wind shear. Tropical Cyclone Tej could continue to intensify rapidly during the next 24 hours.

Tropical Cyclone Tej will move around the southwestern part of a high pressure system over South Asia. The high pressure system will steer Tej toward the northwest during the next 24 hours. On its anticipated track, Tropical Cyclone Tej will be east of Socotra in 12 hours. The core of Tej’s circulation that contains the strongest winds will pass east of Socotra. Bands in the western side of Tropical Cyclone Tej will bring gusty winds and locally heavy rain to Socotra. Heavy rain could cause flash floods in some locations. Tropical Cyclone Tej will approach the coast between Harrah, Yemen and Salalah, in 48 hours.

Tropical Cyclone Forms Over the Arabian Sea

A tropical cyclone formed over the Arabian Sea on Friday evening. At 11:00 p.m. EDT on Friday the center of Tropical Cyclone 05A was located at latitude 10.0°N and longitude 58.8°E which put it about 600 miles (965 km) southeast of Salalah, Oman. The tropical cyclone was moving toward the west-northwest at 8 m.p.h. (13 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 997 mb.

The circulation around Tropical Cyclone 05A organized quickly over the Arabian Sea on Friday evening. The inner end of a rainband wrapped around the center of the tropical cyclone’s circulation. A broken ring of thunderstorms surrounded the center of circulation and the strongest winds were occurring in that ring of storms. Bands of showers and thunderstorms were revolving around the center of circulation. Storms near the center generated upper level divergence that pumped mass away from the tropical cyclone. Winds to tropical storm force extended out 140 miles (220 km) from the center of Tropical Cyclone 05A.

Tropical Cyclone 05A will move through an environment very favorable for intensification during the next 24 hours. The tropical cyclone will move over water where the Sea Surface Temperatures are near 29°C. It will move through a region where the upper level winds are weak and there will be little vertical wind shear. Tropical Cyclone 05A is likely to intensify to the equivalent of a hurricane/typhoon during the next 24 hours.

Tropical Cyclone 05A will move around the southwestern part of a high pressure system over South Asia. The high pressure system will steer the tropical cyclone toward the northwest during the next 24 hours. On its anticipated track, Tropical Cyclone 05A will move closer to Oman.

Tropical Cyclone Sitrang Brings Wind and Rain to Bangladesh

Tropical Cyclone Sitrang brought wind and rain to Bangladesh on Monday. At 5:00 p.m. EDT on Monday the center of Tropical Cyclone Sitrang was located at latitude 24.6°N and longitude 91.2°E which put it about 45 miles (75 km) northeast of Dhaka, Bangladesh. Sitrang was moving toward the north at 35 m.p.h. (55 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 Sitrang moved quickly across the northern Bay of Bengal and over Bangladesh on Monday. The heaviest rain was falling in bands in the northern side of Sitrang’s circulation. Bands in the southern half of Tropical Cyclone Sitrang consisted primarily of showers and lower clouds. Winds to tropical storm force extended out 60 miles (95 km) from the center of Sitrang.

A high pressure system over Southeast Asia will steer Tropical Cyclone Sitrang quickly toward the north-northeast during the next 24 hours. On its anticipated track Sitrang will move across Bangladesh and over northeastern India. Tropical Cyclone Sitrang will drop locally heavy rain over Bangladesh and northeastern India. Heavy rain could cause flash floods in some locations. Sitrang will weaken steadily as it moves farther inland.

Tropical Cyclone Sitrang Develops over Northern Bay of Bengal

Tropical Cyclone Sitrang developed over the northern Bay of Bengal on Sunday. At 11:00 p.m. EDT on Sunday the center of Tropical Cyclone Sitrang was located at latitude 18.3°N and longitude 89.4°E which put it about 360 miles (580 km) south-southwest of Chittagong, Bangladesh. Sitrang was moving toward the north-northeast at 13 m.p.h. (20 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.

The circulation around a low pressure system over the northern Bay of Bengal strengthened on Sunday and the India Meteorological Department designated the system as Tropical Cyclone Sitrang. The distribution of thunderstorms around Sitrang was asymmetrical. Thunderstorms were occurring in bands in the northern side of Tropical Cyclone Sitrang. Bands near the center of Sitrang’s circulation and in the southern half of the tropical cyclone consisted primarily of showers and lower clouds. Tropical Cyclone Sitrang was moving under the western end of an upper level ridge over Southeast Asia and the Bay of Bengal. The ridge was producing southerly winds that were blowing toward the top of Sitrang’s circulation. Those winds were causing moderate vertical wind shear and they were also causing the asymmetrical distribution of thunderstorms. Winds to tropical storm force extended out 60 miles in the eastern side of Tropical Cyclone Sitrang. The winds in the western half of Sitrang were blowing at less than tropical storm force.

Tropical Cyclone Sitrang will move through an environment somewhat favorable for intensification during the next 18 hours. Sitrang will move over water where the Sea Surface Temperatures are near 30˚C. However, the upper level ridge over Southeast Asia and the Bay of Bengal will continue to cause moderate vertical wind shear. The wind shear will inhibit intensification. Tropical Cyclone Sitrang could strengthen during the next 18 hours before it makes landfall in Bangladesh.

Tropical Cyclone Sitrang will move around the western end of a high pressure system over Southeast Asia. The high pressure system will steer Sitrang toward the north-northeast during the next 24 hours. On its anticipated track Tropical Cyclone Sitrang will reach Bangladesh in less than 24 hours. Sitrang will bring gusty winds and locally heavy rain to Bangladesh. Heavy rain could cause flash floods in some locations. Tropical Cyclone Sitrang could cause a storm surge of five feet (1.5 meters) along the coast of Bangladesh.

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 Burevi Stalls over Gulf of Mannar

Tropical Cyclone Burevi stalled over the Gulf of Mannar on Friday. At 4:00 p.m. EST on Friday the center of Tropical Cyclone Burevi was located at latitude 9.0°N and longitude 79.4°E which put it about 80 miles (130 km) east of Toothukudi, India. Burevi was nearly stationary. 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 Burevi stalled over the Gulf of Mannar between Sri Lanka and the southern tip of India on Friday. Although the center of Burevi was over water, the tropical cyclone weakened since some of the circulation passed over Sri Lanka or southern India. The parts of the circulation that were over land experienced increased friction and were unable to extract as much energy from the surface. The wind speeds around Tropical Cyclone Burevi decreased gradually as a result of more friction and less available energy.

Tropical Cyclone Burevi dropped locally heavy rain over parts of southern Tamil Nadu and Kerala in India. Persistent rain fell in some locations because Burevi stalled. If the rain continues to fall over the same locations, then flash floods are likely to occur.

A high pressure system over India could start to push Tropical Cyclone Burevi toward the west during the weekend. Burevi will weaken further if the center moves across southern India. Tropical Cyclone Burevi could strengthen slowly next week, if the circulation is still relatively intact when it reaches the Arabian Sea.

Tropical Cyclone Burevi Rains on Sri Lanka and Southern India

Tropical Cyclone Burevi dropped rain on northern Sri Lanka and southern India on Wednesday night. At 10:00 p.m. EST on Wednesday the center of Tropical Cyclone Burevi was located at latitude 9.1°N and longitude 80.4°E which put it about 50 miles (80 km) south-southeast of Jaffna, Sri Lanka. Burevi 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 center of Tropical Cyclone Burevi made landfall on the coast of Sri Lanka north of Trincomalee on Wednesday. The center moved westward across northern Sri Lanka after it made landfall. Bands of showers and thunderstorms in the northern and western parts of Burevi dropped rain over northern Sri Lanka, southern Tamil Nadu and southern Kerala. Prolonged rain could cause flash floods in some locations.

Tropical Cyclone Burevi could weaken during the next few hours while the center is over northern Sri Lanka. The center of Burevi will move over the Gulf of Mannar in a few hours. The center of Tropical Cyclone Burevi could make another landfall on the coast of southern India near Thoothukudi in about 18 hours. Burevi will move across the southernmost parts of Tamil Nadu and Kerala. Tropical Cyclone Burevi could move over the Arabian Sea in about 36 hours. Burevi could slowly strengthen when it moves over the Arabian Sea.
