Milton just Category 5! I guess this isn't the forum for hurricane discussion lol. Any recommendations for places that people actually talk about this stuff?

In the thread created for the storm? This is the pre-invest thread.

Pardon my stupidity. Didn't realize the top 3 threads were pinned so I just saw Helene at the top and assumed there wasn't anything for Milton 🤦‍♂️

Yeah, thanks for the reminder.  I'll release Helene and pin Milt.

Another CAG in 7-10days (850 wind vector anoms not as NWesterly as past week) gefs been looking fertile, could be similar evolution to last one (further south maybe) If continental wave state leaves a window for something to go warm core will have to see. Will watch nhc 7d

“The MJO continues to be a significant player in the global tropics. The RMM index currently places the enhanced convective envelope over the Indian Ocean. Dynamical model MJO forecasts depict eastward propagation of the intraseasonal signal into the Maritime Continent and Western Pacific during the next several weeks, with a more suppressed convective pattern developing across North America in the wake of the MJO. Tropical cyclone (TC) activity is favored to be greatest over the Indian Ocean and Western Pacific during weeks 2 and 3. The suppressed phase of the MJO is depicted over the Americas during this period which would tend to inhibit TC formation, however potential destructive Kelvin wave interference leads to lingering chances for TC activity on either side of Central America throughout the forecast period.

GFS CMC and Euro have this as an entity, very weak, making it across the MDR into or just north of the Islands

This is wsw and slow to Intensify, euro op starts to deepen it after the leeward islands.  With the large anticyclone in the Atlantic with the wsw heading and slow development…. def monitoring

Something to watch. Currently, it would appear that it would be headed for Mexico if it were to develop due to the weather over the United States currenty. However, 240hrs is a lifetime.

The chances on this (I94L) down to 30% but GFS, Euro, AIFS and ICON all have a weak to moderate storm by the windwards day 6.  Hurricane models have a 6 hr frame where the wind is TS in the beginning of the run then they disappear it.

Back to 50%

Global models are in rare agreement as to the placement of the system. Timing is off by a day or so between them.

GFS hustles it north of PR and sends into Hispaniola

Euro, CMC and Icon just north of Hispaniola

NHC still at 50% for the atlantic system, but the GFS/Euro have backed off. Icon/Ukie still on it. Hurricane models also backed off, but they haven't updated to 12z yet. Currently its a bit of a mess

The western Caribbean system may still happen as NHC is at 20% for that one.  It's a matter of where it forms as it could form on land, it could form just offshore and move inland or it could form further offshore develop into a tropical storm and move inland.
