Tropical Cyclone Asna Weakens East of Oman

Tropical Cyclone Asna weakened over the northern Arabian Sea east of Oman on Sunday.  At 5:00 p.m. EDT on Sunday the center of Tropical Cyclone Asna was located at latitude 21.4°N and longitude 61.4°E which put the center about 185 miles (300 km) east-northeast of Masirah Island.  Asna was moving toward the southwest at 6 m.p.h. (10 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 994 mb.

Tropical Cyclone Asna moved into a large mass of dry air over the Arabian Sea east of Oman on Sunday.  The dry air caused the thunderstorms in Asna’s circulation to dissipate.  Tropical Cyclone Asna still had a well defined low level circulation on Sunday afternoon, but the circulation was very shallow.  Bands of showers and lower clouds were revolving around the center of Asna’s circulation.  However, there were no thunderstorms and there wasn’t any upper level divergence.

Tropical Cyclone Asna will move through an environment unfavorable for intensification during the next 24 hours.  Asna will move over water where the Sea Surface Temperatures are near 28°C.  However, it will remain within the large mass of dry air.  The dry air will prevent the formation of new thunderstorms.  Tropical Cyclone Asna will weaken during the next 24 hours as the low level circulation gradually dissipates.

Tropical Cyclone Asna Spins South of Pakistan

Tropical Cyclone Asna was spinning over the Arabian Sea south of Pakistan on Saturday.  At 5:00 p.m. EDT on Saturday the center of Tropical Cyclone Asna was located at latitude 23.2°N and longitude 62.9°E which put the center about 275 miles (445 km) west-southwest of Karachi, Pakistan.  Asna was moving toward the west at 9 m.p.h. (15 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.

Tropical Cyclone Asna strengthened on Saturday as it moved across the northern Arabian Sea south of Pakistan.  The inner end of a rainband wrapped around the western and southern side of the center of Tropical Cyclone Asna.  Thunderstorms were occurring in bands in the northern and western parts of Asna’s circulation.  Bands in the southeastern part of Asna consisted primarily of showers and lower clouds.  Storms near the center of Asna’s circulation generated upper level divergence that pumped mass away to the west of the tropical cyclone.

Winds to tropical storm force extended out 100 miles (160 km) from the center of Tropical Cyclone Asna.

Tropical Cyclone Asna will move through an environment somewhat favorable for intensification during the next 24 hours.  Asna will move over water where the Sea Surface Temperatures are near 28°C.  It will move through a region where the upper level winds are weak and there will be little vertical wind shear.  There is a large mass of drier air over Southwest Asia.  The circulation around the northern side of Asna could draw drier air into the tropical cyclone.  Tropical Cyclone Asna could strengthen a little more during the next 24 hours, if Asna does not pull too much drier air into its circulation.

Tropical Cyclone Asna will move around the southeastern part of a high pressure system over Southwest Asia.  The high pressure system will steer Asna toward the west during the next 24 hours.  On its anticipated track, Tropical Cyclone Asna will move toward Oman.

 

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 Shaheen/Gulab Makes Landfall in Oman

Tropical Cyclone Shaheen/Gulab made landfall on the north coast of Oman on Sunday. At 5:00 p.m. EDT on Sunday the center of Tropical Cyclone Shaheen/Gulab was located at latitude 23.6°N and longitude 57.1°E which put it about 25 miles (40 km) southwest of Al Suwaiq, Oman. Shaheen/Gulab was moving toward the west-southwest at 8 m.p.h. (13 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 985 mb.

Tropical Cyclone Shaheen/Gulab made landfall on the north coast of Oman near Al Suwaiq on Sunday. Shaheen-Gulab was the equivalent of a strong tropical storm at the time of landfall. It was producing gusty winds and dropping heavy rain on parts of the northern coast of Oman. There were already reports of flash flooding causing casualties and damage in northern Oman. Winds to tropical storm force extended out about 80 miles (130 km) from the center of circulation. The was a ring of thunderstorms around the center and the strongest winds were occurring in that ring of storms. Bands of showers and thunderstorms were revolving around the core of the tropical cyclone.

Tropical Cyclone Shaheen/Gulab will move south of a high pressure system over Southwest Asia. The high will steer Shaheen/Gulab toward the west-southwest during the next 36 hours. Tropical Cyclone Shaheen/Gulab will weaken steadily as it moves over mountains in northern Oman. Shaheen/Gulab will continue to drop locally heavy rain over the normally dry region during the next day or so and more flash floods are likely to occur.

It is very rare for a tropical cyclone to thread the needle and move so far to the west over the Gulf of Oman. The small size of Tropical Cyclone Shaheen/Gulab allowed much of its circulation to remain over the warm water in the Gulf of Oman. Drier air over Iran and the Arabian Peninsula was confined to the periphery of the circulation. The inner core of Shaheen/Gulab remained intact. Tropical Cyclone Shaheen was even more unusual because it started as Tropical Cyclone Gulab over the Bay of Bengal.
