The latest picture of Hurricane Olivia's forecast track is within this article.
Sunday, Sept. 9
At 5 a.m. the center of Hurricane Olivia was located about 731 miles ESE of Hilo, Hawaii
Sustained winds are near 75 mph, with gusts up to 90 mph.
Olivia is moving toward the west near 16 mph. Olivia is expected to continue moving westward, but at a slightly slower forward speed through early Monday.
A gradual turn toward the west-southwest is expected starting late Monday. This track could bring the outer circulation of Olivia close to the Hawaiian Islands starting Tuesday night.
Little change in strength is forecast during the next couple of days, and Olivia is expected to remain a hurricane through Monday night. Some gradual weakening is possible on Tuesday, but
Olivia will likely remain a threat to the Hawaiian Islands early this week.
Hurricane-force winds extend outward up to 30 miles from the center and tropical-storm-force winds extend outward up to 120 miles
The estimated minimum central pressure is 989 mb (29.21 inches).
Saturday, Sept. 8
The center of Hurricane Olivia is located about 1110 miles east of Hilo.
Sustained winds are at 85 mph, with gusts up to 110 mph. Olivia is moving toward the west near 15 mph.
This general motion is forecast to continue for the next couple of days, with a west-southwestward turn anticipated by Tuesday. On the forecast track, Olivia will move into the Central Pacific basin in the next 12 hours, and could be approaching the Hawaiian Islands on Tuesday.
Olivia is forecast to stay a hurricane for the next couple of days while the system is experiencing light shear, balanced by very dry air and marginal but warming sea temperatures. While the forecast is flat-lined through 48 hours, don't be surprised if the system's intensity fluctuates upward at times, as many eastern Pacific cyclones have done so this season within a marginal environment.
After the weekend, most of the guidance indicates that westerly shear should increase, which will likely cause weakening while Olivia approaches the Hawaiian Islands.
Hurricane-force winds extend outward up to 30 miles from the center and tropical-storm-force winds extend outward up to 115 miles.
The estimated minimum central pressure is 983 mb (29.03 inches).
Norman continues to weaken as it moves away from the state.
Olivia has weakened to a Category One hurricane with winds of 90 mph. Motion is to the WNW at 15 mph. It's located 1200 miles east of Hilo. Olivia is forecast to continue to weaken Saturday then maintain Category One strength Sunday into Monday. On Tuesday wind shear should weaken Olivia into a tropical storm.
On it's current track it COULD make landfall somewhere between Oahu and the Big Island overnight Tuesday night - Wednesday. The models are split between a landfall around Oahu or a possible path near or south of the Big Island. The official track is right down the middle of those possibilities but favoring the Big Island.
Hurricane hunters sample the environment around the storm Saturday and then fly through the storm Sunday. This should give the computer models better data and result in a more refined forecast this weekend.
Latest track on Hurricane Olivia shows it's currently a Category 2 hurricane, moving west northwest at 15 mph and is expected to pass near or possibly thru the islands late Tuesday or Wednesday.
The National Hurricane Center reports Hurricane Olivia continues to slowly weaken and is expected to cross into the Central Pacific Basin on Saturday.
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 on Saturday night or Sunday.
Maximum sustained winds have decreased to near 110 mph (175 km/h) with higher gusts.
A slow weakening trend is expected during the next few days.
Hurricane-force winds extend outward up to 30 miles from the center and tropical-storm-force winds extend outward up to 115 miles.
9/7 8 a.m.
Hurricane Norman continues to life north and be torn apart by 40-45 kt vertical wind shear. Still a category 1 with maximum sustained winds 75 MPH. Norman is 290 miles NE of Hilo, Hawaii. Light winds, hot and humid conditions this weekend associated with Norman
Olivia is weakening but remains a major hurricane. Category 3 with maximum sustained winds at 115 MPH. About 1465 miles E of Hilo, Hawaii. The track brings the storm near or into the islands Tuesday night into Wednesday. It is expected to downgrade into a tropical storm with wind speeds 39-73 MPH.
High surf warning in effect for East shores of Kauai, Oahu, and Maui. High surf warning for East and North shores of Hawaii island.
The County of Hawaii:
"Due to the forecast weather conditions, the following closures and recommendations are now in effect:
- Boat owners should take measures to secure their vessels until the danger passes. (Hilo Area)
- Oceanfront residents are urged to be on alert for high and dangerous surf conditions through Friday."
9/6, 11 p.m.
Hurricane Norman is weakening and lifting north of the state. High surf will continue to affect east shores Friday.
Hurricane Olivia will continue west guided by a strong ridge of high pressure. It looks more and more likely the storm will approach Hawaiian waters and possibly could impact the islands. The track brings the storm near or into the islands late Tuesday or Wednesday. Computer models are pretty consistent with this expected track.
The intensity forecast is much tougher with a lot of contradictory factors. The storm is a rarer annular hurricane. These hurricanes tend to weaken slower than normal storms.
On the other hand, Olivia will be moving over slightly cooler waters with drier air out ahead of it, that should induce weakening. When the hurricane approaches the islands, it'll be battling wind shear as well. Right now the official forecast weakens Olivia to a tropical storm late Tuesday.
The next update from the National Hurricane Center is at 5 a.m. Friday.
