It is supposed to. Whether it is because of the wind shear or the "drag" of going on land, I'm not sure. Probably both.

Outer rain bands whipping into the big island now. Even that will cause flooding and the center is moving closer.

Prep time is now for most. I saw some wave height graphs peaking over 25 feet but missing the big Island.

22Aug18 2pHST/5pPDT/8pEDT: Winds 150mph(240km/h), moving WNW 8mph(13km/h), pressure 937mb. Continues expected weakening trend.

NOAA Hurricane Hunter aircraft recon that's been providing valuable data have evacuated to the mainland US today. Unknown if US Air Force will continue recon or will go ahead and start sheltering their own aircraft & support equipment.

Models don't fully agree on track yet, thus rain totals are also scattered, but main GFS and Euro models both bring 20+inches to somewhere in the region, less scattered amounts elsewhere, GFS topping out at over 40inches possible. But they both agree on 20+inches possible somewhere in the region so that's the takeaway.

Latest NHC track. Talk about too close for comfort, wow. What a turn.


Weakens to a Cat 2 pretty fast. The numbers are the dewpoints on the islands right now. Green outline is flash flood warnings.





Latest Model tracks:


A few models have it getting closer and 3 models actually have it hitting Oahu

Middle of the night in Hawaii - but seeing NWS & Civil Defense reporting multiple road closures from flooding & landslides on Big Island - scattered rain rates of 1-2inch per hour continue. These rains will slowly spread across other portions of Hawaii.

As of 240aHST/540aPDT/840aEDT an automated USGS rain guage about 8miles West of Hilo, HI has recorded over 9inches(228+mm) of rain in last 24hours.
