Tropical Storm Guillermo weakened further and the Tropical Storm Watch for portions of Hawaii was discontinued. At 5:00 p.m. EDT on Wednesday the center of Tropical Storm Guillermo was located at latitude 21.4°N and longitude 151.7°W which put it about 250 miles (400 km) east-northeast of Hilo, Hawaii and about 400 miles (640 km) east of Honolulu. Guillermo was moving toward the west-northwest at 9 m.p.h. (13 km/h). The maximum sustained wind speed was 60 m.p.h. (95 km/h) and there were wind gusts to 70 m.p.h. (110 km/h). The minimum surface pressure was 1001 mb. The Tropical Storm Watch for Hawaii County and Maui County including the islands of Maui, Molokai, Lanai and Kahoolawe has been discontinued.
Strong southwesterly winds in the upper levels are creating significant vertical wind shear over Tropical Storm Guillermo. The wind shear has distorted the circulation and the only thunderstorms are in outer rainbands well northeast of the center of the tropical storm. The wind shear is expected to continue and Guillermo will continue to weaken during the next several days.
Since Guillermo is no longer producing tall thunderstorms near the center of circulation, it is being steered by winds in the lower troposphere. Those winds are expected to carry the weakening tropical storm north of the Hawaiian Islands. Since Guillermo or its remnants is expected to move north of Hawaii, the Tropical Storm Watch was discontinued.
