UPDATE: 11 a.m.
Weather officials expect Norman — still a major hurricane — to turn to the northwest tonight.
Category 3 Hurricane Norman, with maximum sustained winds of 115 mph, was about 435 miles east of Hilo and 625 miles east of Honolulu and headed west at 8 mph at 11 a.m. today, according to the Central Pacific Hurricane Center.
This general motion is expected to continue today, with a turn toward the northwest tonight and Thursday. On the forecast track, the center of Norman is expected to pass northeast of the main Hawaiian Islands starting later Thursday. Hurricane-force winds extend up to 30 miles from the center and tropical storm-force winds extend 115 miles out.
“Interests in the main Hawaiian islands should monitor the progress of Norman over the next couple of days,” forecasters said.
Some fluctuations in intensity are possible today, followed by gradual weakening from tonight through Thursday night. Norman is expected to remain a hurricane through Thursday, then weaken to a tropical storm. By the end of the five-day forecast period, the storm is expected to dissipate to a remnant hundreds of miles north of Kauai.
High surf warnings for eastern shores of most of the Hawaiian islands are in effect due to Norman. “A large swell from Hurricane Norman will rise today, and peak Thursday along east facing shores of the Big Island, Maui, Molokai, Oahu and Kauai,” the National Weather Service said.
Meanwhile, further east, Hurricane Olivia continues to weaken as it heads west-northwestward.
Located about 1,800 miles east-southeast of Hilo, Olivia clocked in with maximum sustained winds of 100 mph while heading west-northwest at 13 mph, according to the National Hurricane Center in Miami, which monitors the Eastern Pacific. Hurricane-force winds extend outward up to 25 miles from Olivia’s center and tropical storm-force winds extend outward up to 115 miles.
Additional slow weakening is expected during the next few days, and it is expected to cross into the Central Pacific Saturday as a tropical storm. A gradual turn toward the west is expected over the weekend.
By Monday, at the end of the five-day forecast period, Olivia is projected to be about 400 miles northeast of the Big Island with maximum sustained winds of 65 mph.
