Tonight's Upper Air Sounding, Skew-T from Le Raizet, Guadaloupe shows dry air at the 400mb level or about 22,000 feet. That's the narrow angle that goes off to the left side of the diagram between the 400 and 500 mb marks on the left sidebar.
Lines close together indicate moist air and lines spaced apart are drier air.
This data is taken from a weather balloon launched from the ground, and is the opposite measurement of the atmosphere compared to a Hurricane dropsonde. The dropsonde falls through the system, and the weather balloon rises through the system.

The wind barbs on the right side bar are cyclonic, possibly/ probably storm connected, up to the 200 mb level where they become anticyclonic to a height of 100 millibars, or about 50,000 feet.
I believe this type sounding is conducive to some intensification. A Met could probably give us more information along that line.
Anticyclonic winds above cyclonic winds gives the system an exhaust or ventilation.
