Tropical Storm Haikui weakened as it moved southeast of Hainan Island on Saturday.\u00a0 At 10:00 p.m. EST on Saturday the center of Tropical Storm Haikui was located at latitude 17.6\u00b0N and longitude 112.6\u00b0E which put it about 290 miles (470 km) east of Da Nang, Vietnam.\u00a0 Haikui was moving toward the west-southwest at 6 m.p.h. (10 km\/h).\u00a0 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).\u00a0 The minimum surface pressure was 999 mb.<\/p>\n
A combination of drier air and strong vertical wind shear weakened Tropical Storm Haikui on Saturday.\u00a0 Strong northeasterly winds transported colder drier air from eastern Asia into the circulation of Tropical Storm Haikui.\u00a0 The drier air reached the core of the circulation and it prevented the formation of new thunderstorms around the center of circulation.\u00a0 Strong westerly winds in the upper levels were blowing over the top of the circulation.\u00a0 The combination of northeasterly winds in the lower levels and westerly winds in the upper levels produced strong vertical wind shear.\u00a0 The wind shear blew the upper portion of the circulation to the east of the low level core of Tropical Storm Haikui.\u00a0 The core of Tropical Storm Haikui consists of a circular rotation of showers and low clouds.\u00a0 The only thunderstorms are occurring in a rainband on the northeastern periphery of the circulation.<\/p>\n
The strong wind vertical wind shear and drier air should continue to weaken Tropical Storm Haikui.\u00a0 Haikui is likely to weaken to a tropical depression on Sunday.\u00a0 Since the circulation exists primarily in the lower levels, it will be steered by the winds closer to the surface of the Earth.\u00a0 The northeasterly winds in the lower levels will steer Tropical Storm Haikui toward the west- southwest.\u00a0 On its anticipated track Tropical Storm Haikui will pass south of Hainan Island.\u00a0 Haikui or its remnants could reach the coast of Vietnam in 36 to 48 hours.<\/p>\n","protected":false},"excerpt":{"rendered":"
