TNRIS just launched their new Emergency Resources web site just in time for Gustav to touchdown over Texas. The site overlays Doppler weather with a Virtual Earth map for storm tracking. You can also get down to a specific city, by geocoding places in the search box.
There are few things that compare to a hot, heavy, Texas rain pouring down on you during a warm afternoon, but this is ridiculous! Batten down the hatches, Texas! Use this site to plan appropriately.
