C) Minimum pressure height (Not Available in this report)
D) Maximum ESTIMATED surface wind (40kts)
E) Max surface wind position from storm center.
F) Max Flight level wind direction and speed
G) Max Flight level wind position from storm center
H) Minimum central pressure
I) Max flight level temp/Pressure altitude (in meters) outside the center
J) Max flight level temp/Pressure altitude (in meters) inside the center
K) Dewpoint/Sea surface temp in storm center
L) Eye character (if eye is present)
M) Eye shape and diameter (if present)
N) Confirmation of lat/lon/time fix
O) Fix determination by (encoded)
P) Nav fix accuracy in nautical miles
Q) remarks

Hot dang!!! I have contributed something worthwhile
