If anyone cares, a NOAA plane is approaching Helene again. It should just now be entering into the SW quad. Anyone want to posts obs? ... I'm not sure how many people want to follow anyway

Actually, it looks like NOAA9 is also out there with high-altitude dropsondes.

craptacular · #91 Postby **craptacular** » Wed Sep 20, 2006 12:56 pm

Dropsonde in the eye. 960 mb with 12 mph surface wind, so assume 959mb.

The other key value is the position: 25.8N, 56.7W. This is still 0.2 degrees south of the latitude from the NHC's 11AM EDT advisory ... 2.5 hours earlier.

This dropsonde has the highest surface winds I've seen today (86 mph). It's not 90kts, as the advisory lists, but it's interesting in that it's from well to the SE of the center.
