Re: EPAC: ERICK - Hurricane
Numerous IR imagery modes clearly show Erick's eye clearing out.

Re: EPAC: ERICK - Hurricane
To quote Heath Ledger's joker: "And here we go."
It's a small storm that is clearing out a small eye, surrounded by intense convection, no doubt in my mind that this is a major now. These kind of storms go up quick and produce some intense winds, think Felix of '07. I wouldn't be surprised if this was putting down 110-115kt winds currently. Pressure is probably dropping like a rock due to the small core.

Re: EPAC: ERICK - Hurricane
Agree with Chris90, warming eye and sufficiently cold tops in a tight, small core. I'd make this a major right now. Cat 4 will be easy once eye is clear.

Re: EPAC: ERICK - Hurricane
Given no agency had a DT lower than 4.5, 70 knots at 6z was a horrible call by the CPHC.

The eye has already dropped pretty deep into off-white.

Re: EPAC: ERICK - Hurricane
This is a major hurricane right now. At least, it is in my opinion.

Re: EPAC: ERICK - Hurricane
120 kt as peak is more reasonable to me, WMG pixels are beginning to appear in the eye
Hurricane Erick Discussion Number 13
NWS Central Pacific Hurricane Center Honolulu HI EP062019
500 AM HST Tue Jul 30 2019
The eye of hurricane became much more distinct in infrared
satellite imagery overnight, which indicates that rapid
intensification has occurred. The latest intensity estimates
from the satellite agencies are 5.0 (90 kt) from SAB, 5.5 (102 kt)
from HFO, and 6.0 (115 kt) from JTWC. The CIMSS ADT estimate using
the raw T number suggests the intensity is close to 100 kt. For this
advisory, we are intensifying Erick to 100 kt, so it is now a major
hurricane. Note that the initial wind radii for this advisory were
adjusted based on a 0633Z ASCAT pass, which covered nearly the
entire circulation of Erick.
The hurricane's initial motion is 280/15 kt for this advisory. The
mid-level ridge to the north is still forecast to weaken later
today, which is expected to cause a slower forward motion toward the
west-northwest. The track guidance now appears to have somewhat less
spread. The latest ECMWF and its ensemble mean continue to be
slightly faster than the rest of the models. For this advisory, we
are more closely following the latest NOAA corrected consensus
(HCCA) output. As a result, the track has been nudged slightly to
the right of the previous forecast during the 12-48 hour time frame.
After that, the latest track forecast follows the previous forecast
during days 3-5.
The latest estimates for wind shear in the vicinity of Erick appear
to be less than 10 kt from the west. In addition, sea surface
temperatures remain close to 28C along the track for the next couple
of days, and the CIRA Ocean Heat Content values show sufficient warm
water at depth along the forecast track. Therefore, the environment
around Erick will likely remain conducive for additional
intensification during the next 12-24 hours. The current forecast
closely follows the HCCA, as well as the consensus intensity
forecast output, IVCN. Some gradual weakening is forecast to begin
starting around 36 hours, and continuing through 48 hours. After
that time, the circulation around a broad upper-level trough in the
vicinity of the Hawaiian Islands will likely cause a significant
increase in shear (at least 25 kt from the west) as Erick continues
to move toward the west-northwest. Therefore, this advisory
continues to show rapid weakening during the 2-3 day time frame.
This weakening trend will likely persist during days 4 and 5.

Re: EPAC: ERICK - Hurricane
Eye has really warmed the last couple of frames. 110kts as a peak with at least 24 hours remaining with favourable conditions is a bit coservative. Unless magical shear appears or it gets bothered by dry air again, 120kts should be the floor as the peak for Erick.

Re: EPAC: ERICK - Hurricane
First visibles this morning. Thinking this tops out at 120-125kts myself.
