So, most of you are scratching your heads wondering what the Fujiwhara dance is.

Well, as we all said last week, will Philippe get creative? He not only got creative, but took it to a whole other level. How? Well, we could see the Fujiwhara effect with Philippe and Rina.

Ok, ok. So what is the Fujiwhara effect? Here is the NOAA definition: “When two hurricanes spinning in the same direction pass close enough to each other, they begin an intense dance around their common center. If one hurricane is a lot stronger than the other, the smaller one will orbit it and eventually come crashing into its vortex to be absorbed.

Crazy right? This is actually not all that common, so feel honored to witness this Tropical Praying Mantis Dance of Death.

Alright, so you may be asking, “Chad, who will eat whom?” For now, it looks like Philippe could take the lead and win out. This dance could also help Philippe strengthen down the line. Again, lots can change, but this would be cool to see. All in all, models do support a push of both into the Atlantic and do not support much exposure to the states “for now”… lol…

Lastly, as we approach October, we need to be watching the Caribbean for Home Grown Systems and Caribbean Creepers. Right now, the GFS and CMC support some energy pushing into the Gulf. This is over five days out, but we should be on the lookout for this next week.

That’s it for now folks. Enjoy the dance.
