Correct, NOAA2 is leaving. NOAA9 is still sending dropsonde data. I did not see another VDM.

It'll take 'em a bit to get up there anyway ... they have to reach about 22.5N to get into the convection. We could probably start paying attention after noon EDT.

The plane is now in the area of the SW quad of Helene. Anyone have an idea about my question from yesterday regarding the wind reduction factor from 15,000 - 16,000 feet? I know they have the SFMR, but it's nice to have multiple values to compare.
