...and the area east of Marco Island that got the highest wind from Irma's NE eyewall is all swamp and farmland. Nobody/nothing there to sample it. Likewise the area just east of Rockport that got highest winds from Harvey was deserted.

Nate should be closing in on the Mississippi Sound shortly.

Location: 29.9°N 89.1°W
Moving: N at 20 mph
Min pressure: 984 mb
Max sustained: 85 mph

...NATE'S NORTHERN EYEWALL MOVING ONSHORE THE MISSISSIPPI COAST...

[Ken711]

An Air Force Hurricane Hunter aircraft recently measured
a maximum 850-mb flight-level wind of 89 kt and some SFMR values
around 70 kt. Although the SFMR could be affected by wave shoaling
in this case, the data as a whole appear to support an initial
intensity of 75 kt. Nate's central pressure has been rising
slowly, with the latest report from the plane being 984 mb.
