Hurricane Hector Passing Well South of Hawaii, Generating High Surf, Locally Heavy Rain

Published: August 8, 2018

Hurricane Hector will continue to pass well south of Hawaii into Thursday with only some peripheral effects expected in the islands.

Hector is centered more than 200 miles south of Hawaii, moving west.

The tropical storm warning that was in effect for the Big Island has been discontinued.

Hector's intensity has ticked down since Monday, possibly due to the presence of dry air in the environment surrounding Hector, or somewhat marginal ocean heat content.

On Monday, Hector's maximum sustained winds peaked at an estimated 155 mph, just shy of Category 5 intensity, making it the strongest central Pacific hurricane since Ioke in 2006, according to Colorado State University tropical scientist Dr. Phil Klotzbach.

Building subtropical high pressure north of Hector will keep the hurricane on a generally westward course the next several days. 

Projected Path and Intensity

This will keep Hector's eyewall with its strongest winds and heaviest rain well south of Hawaii.

Hector may produce some outer bands of locally heavy rain spreading across the Hawaiian Islands through Thursday or Friday. Some local flash flooding is possible in a few spots, particularly along east-, south- or southeastward-facing slopes of the Big Island.

Swells from Hector will produce surf heights from 12 to 15 feet on east-facing shores mainly for the Puna and Kau districts of the Big Island through Wednesday evening, according to the National Weather Service. Combined with high tides, this could lead to some overwash of low-lying coastal areas and perhaps some beach erosion.
