Hawaii Emergency Management Agency (HI-EMA) continues to work with emergency management and civil defense partners to monitor potential impacts from Hurricane Hector.
Late Friday, Hurricane Hector, swirling in the Pacific some 1,700 miles (2,760 km) east of the Big Island, grew into a "major hurricane", and its maximum sustained winds reached 120 mph (195 km per hour), the US National Hurricane Center said.
Hurricane-force winds extend outward up to 35 miles from the storm's center and tropical-storm-force winds extend outward up to 90 miles.
NOAA's Central Pacific Hurricane Center (CPHC) noted today, August 8 that a Tropical Storm Warning is in effect for Hawaii County.
Hector is moving west at 16mph, maximum sustained winds will reach near 125mph with higher gusts.
A Tropical Storm Warning means tropical storm conditions are expected somewhere within the warning area.
A powerful hurricane expected to pass to the south of the state is forecast to bring dangerously large waves to east-facing shores of some islands starting Tuesday.
A tropical storm warning was in place Wednesday for the Big Island with gusty winds, rain and risky surf possible.
Forecasters expect little significant change in Hector's strength in the coming days.
Surf along east facing shores is already building and will peak later today and tonight, at 12-15 feet for the Big Island and 6-10 feet for Maui County.
Swells generated by Hector will bring large and risky surf to portions of the main Hawaiian islands through tonight.
