Re: 12:40am EDT sonde: 943mb, 8 knots of surface wind

Posted by Chris in Tampa on 9/19/2017, 1:54 am

So while the pressure came up some, it's already falling again and it still seems to be about as strong as it was before crossing over Dominica.

The wind field is expanding in other quadrants too.

For NW quadrant, extent of 10 second estimated surface winds by SFMR:

64 kts: 40 nautical miles (1 minute sustained in 11pm advisory was 25nm)
50 kts: 85 nautical miles before you get to 49 knots (1 minute sustained in 11pm advisory was 40nm)

For the 50 kt wind field in NW quadrant, there were still some 50 knot values out past 85 nautical miles.

Wide view:
