Rain beginning to fall in downtown Honolulu #Iselle #Hawaii

Yup.

[Brent]

Hurricane Central: 2pm HST (8pm EDT) -- East winds sustained 59 mph gusting 72 mph on the 13,800-foot summit of Mauna Kea, #Hawaii. #Iselle

This will be an interesting place...

Don't know why they upped the wind. Recon barely found anything to support 65 kts an hour or so ago. Pressure continues to rise.

Looks like it was never 65 knts at all

SFMR data was 68 knts. Drospondes were higher.

Rain beginning to fall in downtown Honolulu #Iselle #Hawaii

Just trade showers for now. Rainfall directly associated with Iselle is only falling on the big island.

Hurricane Central: 2pm HST (8pm EDT) -- East winds sustained 59 mph gusting 72 mph on the 13,800-foot summit of Mauna Kea, #Hawaii. #Iselle

This will be an interesting place...

Sustained winds at 59mph, despite it being 6 hours away from landfal.

At 13.8k feet though.

How will this affect the Mauna Kea Observatory? I'm sure they have taken safe precautions.

[AFWeather]

Winds in the 40's on the west side of the island, including a gust to 45 mph at the Kona airport. Some funneling going on with the wind direction over on that side.

[supercane4867]

The center continues heading due west based on radar

[Steve820]

It's going to make landfall in Hawaii soon, potentially as a hurricane, let's hope it won't be so destructive for them. Prepare, Hawaii!

[Frank2]

Per radar the center appears to be moving slightly south of west - TWC (Brian Norcross) said an hour ago that the center might cross just south of the Big Island, which would be well south of the remainder of the islands if it took that track, so if if if that happens some good news.

[supercane4867]

Large area of hurricane force wind is located on the north side away from center, if the center going more south than expected that means most of these winds will impact land

[Alyono]

I'm fixing a slightly north of due west motion and the last recon fix also showed slightly north fo deu west (between 275 and 280)

[WeatherGuesser]

I can't tell if it's a south jog or just a wobble.

[tallywx]

It's going to be interesting to see whether the frictional differentials between wind going up and over the 13800' peaks of the Big Island versus the easier path of south and around will force the center south of the island. These are mass-scale land effects for which there's no analog in the Atlantic Basin (or in many places in the world for that matter). We shall see.

[Kingarabian]

Hard to tell with convection all over the place.

It has to go south soon then.

ATCF has it at 19.0. South Point is 18.9N.
