Very concerned for Ft. Myers metro area. Increasing likely that some of the greatest surge will be focused there, or somewhere close to there, due to maximized onshore flow and concave shape of the coastline.

Fiona may be playing a direct role in amplifying the wave behind it via Rossby wave radiation toward Fiona's SE. The zonal separation (~1800 km) is consistent with such a mechanism, as studied in @benschenkelwx (2016, 2017).

A couple of ventilation pathways might be at play that have weakened Lee: 1) radial pathway upshear and 2) downdraft pathway in the mesoscale descending inflow of the stationary band complex. Additionally, the first pathway can lead to low-level outflow upshear.

I believe we’re seeing the initial signs, via TDR analysis, of shear starting to affect Beryl. Distinct updraft-downdraft asymmetry has developed in the eyewall. Radial flow asymmetries are also becoming more pronounced. If trends continue, weakening should commence soon.

Latest NOAA TDR profile analysis continues to show deep, strong downdrafts on the upshear side of the eyewall exceeding -5 m/s (circled below). Dry air is eroding the W side of the storm too. A lag in the intensity response, but the structural signal for weakening is there.

That said, the storm does not look particularly healthy. The VDM notes a max flight level temp outside of the 5 nm core, and the data stream shows no real temp spike at all. Pressure has remained stable. Convection cannot seem to sustain and wrap. Still a lot of work to do.

Florence's direction and how much of the circulation is over water vs. land Fri.-Sat. will be critical to surge impacts. A track like the ECMWF that remains offshore will prolong surge over multiple high tides and could promote a coastally-trapped Kelvin Wave that enhances surge.

Forecasted upper-level pattern is conducive for Laura's rapid intensification in Gulf of Mexico. Shear is low, and there are poleward and equatorward outflow channels, facilitated by a upper-level trough to the NW & cutoff to the SE. Question is how fast inner core can organize.

A feature to watch for Fri. is the formation of an intense, deepening mesoscale low at the spearhead of +PV advection/tropopause fold. 12Z ECMWF suggests this possibility. Such features can have very intense squalls associated with their strong dynamic lift & isallobaric winds.

A serious hazard from Ian will be extreme rainfall. The threat of flooding from heavy rain will extend far inland due to 1) slowing of Ian's forward motion, 2) shear-induced lift, and 3) interaction with a frontal boundary. 00Z GFS is forecasting eye-opening numbers >40"!

Looking at the last 5 GFS forecasts verifying at 18 UTC today, this upper low has trended stronger & less negatively tilted, perhaps influenced by outflow from Hurricane Nora. I suspect this trend is responsible for Ida having a bit more of a NNW motion, rather than NW. (2/2).
