Tropical Storm Greg is forecast to pass well south of the Hawaiian Islands of Maui and the Big Island of Hawaii tonight and will have no impact on the weather there.
As of the latest advisory issued by the Central Pacific Hurricane Center in Honolulu on the Hawaiian Island of Oahu, Greg was located roughly 700 miles south-southeast of Honolulu and 535 miles south-southeast of Hilo. With maximum sustained winds of 45 mph, Greg is a minimal Tropical Storm. It is currently moving to the west at 13 mph while its minimum central pressure is 1004 mb or 29.65″.
Greg is expected to continue its westward motion tonight through Thursday night. A turn toward the west-southwest is forecast on Friday and Saturday. While it tracks well south of Hawaii, it is losing strength. Maximum sustained winds are near 45 mph with higher gusts and little change in strength is forecast during the next 12 hours, but after that, a steady weakening is expected. The Central Pacific Hurricane Center says they expect Greg to become a post-tropical remnant low by late Friday or Saturday.
Greg will have no influence on the weather in the state, including the island of Maui which continues to deal with the aftermath of a significant lethal fire weather event which struck on August 8. National Weather Service forecaster Matthew Foster wrote, “A surface high pressure system to the north will drive breezy trade winds through Thursday night, while Tropical Storm Greg passes far south of the state. The dry, stable air and lighter trade winds will continue through the weekend. Expect little rainfall through this period, except for isolated showers along the windward slopes.”
