1 m/s is about 2.237mph. Straight-up conversion...3600 seconds in an hour, ~1600 meters in a mile; multiply by the 3600 and divide by the 1600. Thanks to Mark/Bloodstar for correcting me on the meters vs. yards in a mile issue.
The GFS is showing why we don't use 16 day model runs to forecast tropical cyclones. You'd be much better off going with climatology at that rate...truthfully, beyond 7 days you would be. Just watch it for now and don't worry about what the long-range says: there will be plenty of time to prepare should it become necessary.
