The main areas of this site are Tropical Weather, Local Weather, Expert Weather, Weather Tools, Weather Q & A, and Weatherboy Online. The two areas that would be most informative for students are the Local Weather and the Weatherboy Online. The Local Weather allows students to get weather information from any area in the United States. The information includes 4 day forecasts, satellite images, precipication and radar images.
