ATL: FRANKLIN - Post-Tropical - Discussion

[Chris_in_Tampa]

8am EDT on August 23rd: Tropical Storm Franklin is making landfall along the southern coast of the Dominican Republic near Barahona.

24 hour radar loop from the Dominican Institute of Civil Aviation of #Franklin through Wednesday, August 23rd at 11:45 UTC. (7:45 am EDT)

Convection around the CoC has now taken over from that which had been occurring overnight:

Ok you guys something is kinda wrong where i am and i’m trying to find an explanation. I’m in Santiago right now it’s not raining at all and the sun wants to come out at times i just saw on the NHC website that Franklin is making landfall in Barahona in the south but i just saw a video of barahona there’s barely anything from what i’ve seen because of that a lot of Dominicans are not taking the storm seriously. Is this the famous saying “The calm before the Storm” ? What’s going on ?

From what I'm seeing on recent satellite imagery, Santiago should be getting quite a bit of rain and thunderstorms shortly:

I wouldn’t be surprised to see Franklin start tightening up pretty quickly after leaving Hispaniola. Storm somehow looks better over land than it did over water, and there isn’t much of a core to disrupt. We’ve seen a few like that in recent years

Franklin still has a rather disorganized wind field. Santo Domingo peak wind only 20 kts as it passed. Lots of rain, though.

I guess the best thing that could had happened to Franklin of for it to move across the high terrain of Hispaniola so that a new LLC forms much closer if not underneath its vigorous MLC.

Franklin has a pretty good shot at becoming our first major hurricane of the season on its way OTS.

As I predicted a much better defined COC after Hispaniola.

Quite interesting how we've seen so many of these weak, diffuse systems tighten up after moving over Hispaniola while stronger systems are disrupted beyond the point of recovery, is this helping add to the vorticity when there's otherwise not a lot there?

Weak and spread out system tend to tighten up moving over mountains and land because of fiction and convergence. A solid core is going to be gutted as 1. It is cut off from its energy source, 2. mountains slow down the lower level winds and scramble things up...

What explains a hurricane like Georges moving over both Hispaniola AND those big Eastern Cuba mountains and still not dropping to a tropical storm storm and then became a cat2 over Key West? Just imagine if it didn't go over those mountains we'd probably would have had a possible cat5 for FL and a strong hurricane in MS

This is illustrated very well in the last frame of the 925mb vorticity product over the last 5 days:
