The 12z NAM (12km nest) trended towards the euro solution. Should mean the 12z GFS trends west

Do you have access to the extended-range EPS members? That “cluster” could still turn prior to reaching Puerto Rico.

ICON 12Z ended north of 0Z, looks like models trending north again. That weak Bermuda high this season might end up being the saviour...

EDIT: nvm looks like EURO trending west again

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.

Wow look at those low dew points into South Florida, same trough that could turn future Sam northward. It is a powerful trough to say the least. Won’t be feeling like hurricane weather here if the GFS is right that is fore sure :eek:
