ATL: BERTHA - Recon

[NDG]

AF304
Observation #13 (Looks like they scraped the western portion of the center)

Not really, notice that the winds reported are still from the SW and pressure falling. They were still on the SE quadrant of the storm.

Yeah, I read that as 1001 mb, but nonetheless they still are nearing the center

I posted the latest VDM earlier but since there's something of note I'll post it here -

Based on the planned flight path and the last given position southeast of Andros Island, I believe that the upper-level mission NOAA9 "Gonzo" has concluded its operations over Bertha and will be headed to a landing in Fort Lauderdale, so I won't be posting additional information on this flight.
