Weakening Tropical Storm Lane Moves Away from Hawaii

A weakening Tropical Storm Lane moved away from Hawaii on Saturday.  At 11:00 p.m. EDT on Saturday the center of Tropical Storm Lane was located at latitude 19.5°N and longitude 160.2°W which put it about 195 miles (310 km) southwest of Honolulu, Hawaii.  Lane 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 998 mb.  All Tropical Storm Warnings and Watches for the Hawaiian Islands have been discontinued.

An upper level trough west of the Hawaiian Islands produced strong southwesterly winds which blew the upper portion of the circulation of former Hurricane Lane off the lower part of the circulation.  Tropical Storm Lane consisted primarily of a well develop low level circulation of bands of showers and lower clouds.  A few thunderstorms continued to develop in outer bands on the eastern side of the circulation.

Since Tropical Storm Lane exists primarily in the lower levels of the atmosphere, it is being steered westward by a subtropical ridge over the Central Pacific Ocean.  A general westerly motion is forecast during the next several days.  The upper level trough will continue to cause strong vertical wind shear and Tropical Storm Lane will continue to weaken.
