Doppler radars are one of the maps that use on almost a daily basis to view when either rain is coming or how big a a storm is going to be. It uses the Doppler effect which is the change in frequency of an object that is moving. This exact map if from Hurricane Charley that made landfall around the Fort Myers area. If you look at the map the eye is very distinct, its the little circular object above the y in myers. According to Doppler radars there are different color types that are used. Green, yellow, red and purple with variations of them. Green illustrates light, yellow is for moderate while red is heavy and purple is extreme.

This Hurricane was seem to be one of the first ones to hit the west coast of florida in a long time. I was actually at my home in South Florida at the time this hurricane hit and it was very devastating to everyone in the area that lost lots, i do not believe this hurricane was as heart breaking as Hurricane Katrina and Sandy. I believe everyone that looks up the weather on the computer use the Doppler radar.
