So, it may be at or below 980 mb, when earlier pass was 985? It has went from 988 to 980 or less in two passes? :eek:

Recon supports 95 mph, NHC will probably go with 90.

Looks like it's going to get up to a Cat 2 before landfall with at least 100mph.

I am going with 120 at landfall. Based on current trends on IR and recon.

With it moving so fast I would guess its a little harder to hit the center. A target moving at 22mph must be a little harder

It's possible it could get up to cat 3. 115mph to 120mph is possible. The 22mph forward speed will definitely give the Eastern quadrant a boost compared to a slower moving storm. It'll also make the west side very weak comparatively.

One positive is it won't be a cat 2/3 very long so the surge may underperform.

Center at 26.4N, 88.4W. Well west of NHC's track. Still not much wind west of the center.

Looks like those east of landfall will face the burnt of Nate. People living west of the area of landfall might not find that much wind.

Heavy duty 55 mm/hr rain rate reported by AF305.

The formula im aware of is 2x forward speed =44mph in difference between the strong and weak sides of a hurricane.

If max winds are 100mph at landfall, the west side should only get 55mph winds according to the formula.
