GFS shows Elsa getting much stronger once it enters the Caribbean. This could be an ugly run.

GFS stronger mid-run which must mean that it's finding favorable conditions downstream.

Going to avoid Hispanola again this run. GFS is very consistent with this storm.

Looks to be a close call with Jamaica after passing Hispaniola to the south.

GFS landfalls on Jamaica, but further north compared to 06z. This time its landfall with Jamaica hurts it more than in the 06z version, but those things are determined by such tiny details that I don't think we should put much value into it one way or the other.

Again, it's threading the needle as it passes just south of Hispanola but weakens as it barely crosses north of Jamaica.

GFS showing it getting stronger between Jamaica and Cuba @ 90 hours. Atlantic high pressure is backing NE ward as the trough lifts out of New England and the Canadian maritimees. The way to a block would be for ridging in the southern plains to bridge over the top or for a pulse off the Atlantic Ocean. That doesn't appear to be what the GFS is thinking. I'd expect this to turn up and hit South Florida.

Subject to TONS of change going forward but I can't help but get a Charleyesque vibe here. Charley went S of Jamaica.
