Changes from the previous Vortex Data Message with an eye fix 1 hour 40 minutes prior (note; there is no new max wind info) -

- Movement of 3 minutes north, 11 minutes west (track of approx. 285 degrees; don't ask for distance or speed or my computer will spontaneously combust :-)
- Minimum pressure down another 10 mb to 904 mb (last report had an extrapolated pressure of 914 mb)

I found this Indonesian Website (why, I don't know) where you can just type in lat-longs in either minutes or decimal format and it automatically gives angle and speed.

http://www.indo.com/distance/

Key thing to keep in mind is official NHC advisories use decimal lat longs (20.5N, for example, 10 tenths in a degree) while VORTEX statements from recon are in minutes (20.5N is then 20 degrees 30 minutes North, 60 minutes in a degree.) Confusion on this point has caused infinite confusion over the years.

On that website a recon vortex is entered with a colon (20:30) and decimal is entered with a decimal (20.5).
