Norman has been downgraded to a tropical storm and is moving away from the islands.
A large east swell from Norman will begin to subside this afternoon, and shift out of the northeast tonight and Saturday.
Still moving toward us is weakening Hurricane Olivia. While it’s still far to the east, over 1,300 miles away, the current track doesn’t look good.
As of 11 a.m., Olivia’s cone of uncertainty now encompasses Hawaii island, all of Maui County, and all of Oahu, This means the storm has the potential to move within the area. Building high pressure will keep Olivia on a westward track.
Olivia continues to weaken and is now a category 2 hurricane with 110 mph winds. It is expected to continue this gradual weakening trend as it crosses into the Central Pacific on Saturday.
As Olivia approaches the islands, the strength of the system could be anywhere from a strong tropical storm to a weak category 1 hurricane. However, the current forecast has Olivia weakening to a tropical storm Tuesday morning.
The timeline for the possible closest point of approach will be sometime early Wednesday morning to late Wednesday afternoon. Some forecast models have it moving slightly quicker and over the islands early Wednesday morning near Oahu, while other models have it near the Big Island on Wednesday afternoon.
While it’s too early to know the exact details, residents should prepare for heavy rain and flooding, strong tropical storm force winds, and large storm surge and surf.
Keep in mind, changes will occur in forecast track and intensity as the storm gets closer.
At 11:00 a.m., the center of Hurricane Olivia was located about 1,375 miles east of Hilo. Olivia is moving toward the west-northwest near 16 mph, and this general motion is forecast to continue through Saturday. A gradual turn toward the west is expected Saturday night or Sunday.
Maximum sustained winds have decreased to near 110 mph with higher gusts. A slow weakening trend is expected during the next few days.
Hurricane-force winds extend outward up to 30 miles (45 km) from the center and tropical-storm-force winds extend outward up to 115 miles.
