Hey Rick,
This is a great website for tracking the tropics, the person "Jay" that designed this website put dozens of radar, satellite, vapor loop, sea surface temp, wind direction/speed maps and links to all the important websites, NOAA, Wunderground, Weather Channel, Accuweather, etc, etc all on one webpage, It's a great one stop shop, for all your mapping needs!
I've got it bookmarked on my laptop and Iphone.
