This is the national hurricane center site filled with great interactive links about hurricanes
http://www.nhc.noaa.gov
This site has data (latitude/longitude, wind speed, air pressure) for all hurricanes and tropical storms
since the late 1800s. It also has a very cool plotting program which allows you to see the path and
intensity of those storms (java plot). This is a fun place!
