Tropical Cyclone Biparjoy continued to move slowly toward the north over the Arabian Sea on Saturday night. At 11:00 a.m. EDT on Saturday the center of Tropical Cyclone Biparjoy was located at latitude 18.1°N and longitude 67.5°E which put it about 475 miles (765 km) south of Karachi, Pakistan. Biparjoy was moving toward the north at 6 m.p.h. (10 km/h). The maximum sustained wind speed was 105 m.p.h. (165 km/h) and there were wind gusts to 125 m.p.h. (200 km/h). The minimum surface pressure was 962 mb.

Tropical Cyclone Biparjoy appeared to be pulling drier air from India into the northern part of the circulation. Bands in the northern half of Biparjoy consisted primarily of showers and lower clouds. Thunderstorms were occurring in bands in the southern half of Tropical Cyclone Biparjoy. Storms near the center of Biparyjoy generated upper level divergence that pumped mass away to the west of the tropical cyclone. Winds to hurricane/typhoon force extended out 30 miles (50 km) in the southeastern quadrant of Tropical Cyclone Biparjoy. Winds to tropical storm force extended out 175 miles (280 km) from the center of Biparjoy’s circulation.

Tropical Cyclone Biparjoy will move through an environment somewhat favorable for intensification during the next 24 hours. Biparjoy will move over water where the Sea Surface Temperatures are near 31˚C. It will move under the axis of an upper level ridge over the Arabian Sea. The upper level winds are weak near the axis of the ridge and there will be little vertical wind shear. However, drier air in the northern side of Tropical Cyclone Biparjoy will continue to inhibit formation of thunderstorms in the that part of the circulation. In addition, Biparjoy has been moving slowly and the wind could mix cooler water to the surface of the Arabian Sea. Tropical Cyclone Biparjoy could weaken during the next 24 hours if the drier air in the northern part of the circulation and the mixing of cooler water to the surface inhibit the formation of thunderstorms near the core of the circulation.

Tropical Cyclone Biparjoy will move around the northwestern side of a high pressure system over India during the next 24 hours. The high pressure system will steer Biparjoy slowly toward the north. On its anticipated track, Tropical Cyclone Biparjoy could approach the coast near the border between India and Pakistan in four days.
