Tropical Cyclone Biparjoy was nearing the Indus River Delta on Wednesday night. At 11:00 p.m. EDT on Wednesday the center of Tropical Cyclone Biparjoy was located at latitude 22.8°N and longitude 67.0°E which put it about 150 miles (245 km) south of Karachi, Pakistan. Biparjoy was moving toward the north-northeast at 5 m.p.h. (8 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 985 mb.

Tropical Cyclone Biparjoy weakened on Wednesday while it moved over the northern Arabian Sea. More drier air was pulled from South Asia into the northern side of Biparjoy’s circulation. In addition, Tropical Cyclone Biparjoy moved under the southern side of an upper level ridge over South Asia. The upper level ridge produced easterly winds that blew toward top of Biparjoy’s circulation. Those winds caused the vertical wind shear to increase. The effects of the drier air and the increased vertical wind shear caused the distribution of thunderstorms to become more asymmetrical. Thunderstorms were still occurring in bands in the southern part of Biparjoy’s circulation. Bands in the other parts of Tropical Cyclone Biparjoy consisted primarily of showers and lower clouds. Winds to tropical storm force extended out 160 miles (260 km) from the center of Biparjoy.

Tropical Cyclone Biparjoy will move through an environment that will be unfavorable for intensification during the next 12 hours. Biparjoy will move over water where the Sea Surface Temperatures are near 30˚C. However, the upper level ridge over the South Asia will continue to cause moderate vertical wind shear. More drier air will be pulled from South Asia into the northern side of Tropical Cyclone Biparjoy. The drier air will continue to inhibit formation of thunderstorms in the that part of Biparjoy. More vertical wind shear and more drier air will prevent intensification of Tropical Cyclone Biparjoy.

Tropical Cyclone Biparjoy will move around the northwestern side of a high pressure system over the Indian Ocean during the next 24 hours. The high pressure system will steer Biparjoy toward the northeast. On its anticipated track, Tropical Cyclone Biparjoy will reach the coast near the border between India and Pakistan in 12 hours. Biparjoy is likely to be the equivalent of a strong tropical storm when it reaches the Indus River Delta. The India Meteorological Department issued a Cyclone Warning for the Saurashtra and Kutch Coasts. Tropical Cyclone Biparjoy will bring strong winds and locally heavy rain to eastern Pakistan and western India. Heavy rain could cause flash floods in some locations. Biparjoy could also cause a storm surge of up to 7 feet (2 meters along the coast).
