ATL: FRANKLIN - Post-Tropical - Discussion

[Teban54]

The current record for the northernmost Category 5 Atlantic hurricane is held by Lorenzo at 24.3N. Franklin is already at 27.2N, and has a real chance at shattering that record.

Crazy what record warm SSTs can do.

[MarioProtVI]

WTF? Was not expecting to wake up to Franklin like THIS. If it becomes a C5…It wasn’t really supposed to peak until Wednesday!

943 to 938 in less than an hour is crazy.

Eye drop of 936/9 supports 935 mbar, down from 943/9 (942 mbar) just an hour and 35 minutes earlier. That’s a deepening rate of 4.4 mb/hr. If this keeps up for just a few more hours, we would see a Cat 5. A shame that we’ll have to wait until tonight for recon, but this flight has been helpful in showing that Franklin is running 10-15+ kt ahead of satellite estimates; ADT is only around 110-115 kt.

Strange coincidence, but last year we had an open ocean Cat 4 that was the F storm, and an I storm threatening the West Coast of Florida too. Now look at what’s happening.

Beautiful

Franklin is well positioned for GOES-18 to get a great side shot of the storm this morning. A fantastic satellite appearance --

Andrew and Dorian were both north of 25N as Cat 5’s

Oops sorry, got my facts mixed up. Lorenzo was the eaternmost.

[zzzh]

Michael was a cat 5 at 30.0N. But the Gulf is just different from open sea.

[HurricaneEnzo]

Michael was further North wasn't it? Or do you just mean the open Atlantic not including GoM or Carib.
