ATL: ISAAC - Post-Tropical - Discussion

[wxmann_91]

Yeah, I'm not sure why some people were writing this system off earlier today. The Euro has a strong hurricane approaching the Windward Is. just as Florence is approaching the Carolinas. The upper-air conditions look favorable for the at least the next few days, so it's not a totally farfetched scenario.

So just to point something out in light of what the Euro is showing, this is likely to become the infamous "I" storm, and Isaac is the last original I name left...

[bob rulz]

If they both get named at the same time, will the one that was invested first get the H name and the later one the I name? I can never remember for sure the protocol on that (although I also can't remember for sure if it's actually happened!).

The fact that this was posted on Twitter by a very well respected meteorologist should tell you all you need to know.

This meme is so relevant for the switching between the 50-ish storms we'll be tracking next week. Tropics overload.

Yep and interestingly, Florence is the last original "F" storm left.

If 92L does end up becoming a bad storm, I hope it gets the name Isaac so it can be retired. I still have not forgotten about the 2012 incarnation.

[1900hurricane]

It's over 6 hours old now, but here's the latest ASCAT data for 92L.

[cycloneye]

I smell TD in the next few hours.

[Hurricane Andrew]

This one really got in gear over the last 12 to 24.

[AubreyStorm]

Looking great!

[shiny-pebble]

Looks like we'll (probably) have TD 8 and PTC 9 at twelve.



It's September 7th and we have had 4 storms. My vote on that poll before was 5... I'm gonna end up quite wrong...

GFS still showing this as a hurricane approaching the southern coastline of Hispaniola.
The USS Tennessee (ACR-10) got caught in the Santo Domingo harbor back in 1916.
If only they had the GFS back then..

8 AM TWO:

1. Satellite images indicate that the circulation of a low pressure
system located about 650 miles west of the Cabo Verde Islands is
gradually becoming better defined. In addition, the associated
showers and thunderstorms remain fairly concentrated near the
center. This system is expected to become a tropical depression
later today or tonight while it moves slowly westward across the
tropical Atlantic Ocean.
* Formation chance through 48 hours...high...90 percent.
* Formation chance through 5 days...high...90 percent.

that track sure has changed in the last 48 hours, get your preps ready islands

[Hypercane_Kyle]

Yea, this will be upgraded at 11am.

[NDG]

Definitely better organized this morning with deep convection concentrating on the SW quadrant of the COC, still been affected by some NE windshear, not unusual for the eastern MDR.

[1900hurricane]

I'd renumber based on the above microwave pass alone.

[Gustywind]

Latest on SSD.. numbers up to 1.0/1.0 racing westward...

gorgeous view up here

Up here? I always thought you were an extraterrestrial

Easy to see the dry air Florence is struggling with on this one. You have a link to this particular view?
