Hurricane Oho appears to have peaked in intensity and is picking up speed as it moves away from Hawaii into cooler waters.

The storm should not have a direct effect on the main Hawaiian islands, but could bring more moisture and clouds to the Big Island and Maui into Thursday.

At 11 p.m. Tuesday, Oho maintained maximum sustained winds of 105 miles per hour. 

The storm was 515 miles east of Hilo and 695 miles east of Honolulu, moving northeast at 29 mph.

Hurricane-force winds extend outward up to 35 miles and tropical storm force winds extend 175 miles. 

Oho is expected to gradually weaken through Thursday morning and it passes through cooler waters and wind shear. It should weaken to a post-tropical cyclone by Thursday afternoon as it nears the mainland.

Oho may bring near-advisory-level surf to south and east shores of the Big Island. But the island will likely shield most of the waves from reaching other islands, forecasters said.
