HMON is coming in far weaker and further south through 78hrs. Let’s see if it makes that turn to the north again this run.

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.

Yeah the HWRF and HMON shifted back south on this run.

HMON stayed south and has an almost identical solution to the GFS, with a moderate Cat 1 into CA. HWRF took a page out of the last few HMON runs and shifted north after passing the ABC islands, RI’ing into a 90 kt Cat 2 before dry air starts to erode the core.

Yeah in the end it was more north compared to the previous run. Its looking like how strong future Bonnie is after it enter the Caribbean will play a role in the track.

Something else to note, HWRF is also much slower than HMON giving it time to turn north as the ridge weakens.

The ECMWF Ensemble (12z run) now shows only about a 20 - 30 percent chance for a tropical storm. This morning, that was still a bit higher. Quite surprised there is little support for decent strengthening according to the weather models, despite the NHC saying the environment is rather favorable.

Interesting that HWRF (12hr Interpolated) and HMON are both so north from the rest. The Caribbean does seem favourable for intensification so they have a good chance for verifying.

The HWRF has been showing some northerly shear picking up at the end of its last few runs, with PTC2 becoming displaced from its UL anticyclone. It remains to be seen if that actually verifies. No other model has shown it, and while this run keeps intensifying up until landfall, you can tell it’s dealing with something by looking at the ragged simulated IR.

Also finally the HWRF and HMON agree with each other, and aren’t showing opposite extreme solutions.

Hate to break it to you but HWFI (HWRF 6 hr interpolated) did go the opposite way lol

Both the HWRF and HMON shifted north this run. HMON clears Central America. HWRF would've as well if it had a slower forward speed.

Euro, CMC, and ICON all show a SW turn into the Costa Rica/Nicaragua border and a successful crossover into the EPac. PTC2 seems to be trying its hardest to be a 1-for-1 repeat of Cesar ‘96; hopefully its impacts are nowhere near as bad.

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.

Every 12z global model run shows PTC2 either redeveloping over on the EPac side, or surviving the crossover.

Intensities have dropped off on most the guidance to at most a minimal hurricane at landfall in Central America.

HWRF and HMON don’t show PTC2 getting disrupted much by Central America. It makes landfall as a strong TS/low end hurricane and emerges as a moderate to strong TS, with a structure ripe for RI.
