Re: ATL: GRACE - Models
NHC shifted their track further South and West this afternoon, although I'm not sure which model they based it on.

18Z ICON has a pretty realistic solution imo. Stays south of Hispanola and Cuba and goes across the Yucatan making landfall in Mexico as a strong TS.

All models are trending south and west. Likely due to the center of Grace possibly reforming further south and a stronger ridge over the North Gulf.Senobia wrote:NHC shifted their track further South and West this afternoon, although I'm not sure which model they based it on.

Re: ATL: GRACE - Models
The 18z runs so far seem to be aiming at the Yucatán Mexico/Belize by the 84-96 hour range, with the possibility for strengthening in the BoC — very similar to Earl ‘16 and Franklin ‘17.

I am only a meteorology enthusiast who knows a decent amount about tropical cyclones. Look to the professional mets, the NHC, or your local weather office for the best information.

It straight up buries it into southern Mexico. That ridge is supper potent. I hate the heat, but if it protects us from these systems, bring it on.

18z HWRF is further south and wants to douse Haiti. Unfortunately, this scenario looks closer to reality.

HWRF goes over southern portion of Hispanola but is back over water south of Cuba intensifying.

Oh boy, the HWRF sends Grace into the rocket fuel that is the WCar.

HWRF has a weak Hurricane at 72 hours heading for the Yucatan Channel. Also has pinhole so this run could get crazy.

You almost have to admire the HWRF. It’s stubborn and undeterred on Grace becoming a hurricane. Like a backup cheering on its model teammates.

Re: ATL: GRACE - Models

I wonder what's preventing strengthening here? The shear is not that strong.

It's what it does, year in and year out. It could take a water puddle in your yard and turn it into Super Typhoon Tip.

You gotta admire the HWRF's constant positivity when strengthening any storm

You gotta admire the HWRF's constant positivity when strengthening any storm. In just 12 hours HWRF shifted from south Florida to Cancun for it's mainland landfall
.
Panama Canal next?

Re: ATL: GRACE - Models
Ignoring the ridiculous intensity in the Gulf, this HWRF run has a reasonable evolution for Grace based on its current location and trajectory:
1.) it makes landfall in DR and has a center relocation
2.) despite now being south of Cuba, it has a hard time strengthening much (it does get to hurricane intensity but looks to be limited by shear)
3.) it either makes landfall over or passes near the Yucatán Peninsula
4.) it’s able to take advantage of better conditions in the Gulf/BoC and intensify
