NOAA, the source used for this has updated their website in the last year or so.
This is why older today plugins for weather forecasts dont work, because NOAA changed their site for that. I imagine they did the same for their hurricane stuff.
I checked, and this software also gets its data from NOAA.

PocketGear : Hurricane Tracker
Youll probably have to upgrade to 1.1 unless that version doesnt work also. If their latest version inst working, contact the author of it and tell them it doesnt work.
The alternative is just to use NOAA's mobile site, which isnt as good looking and has less features.
