The Watches and Warnings map is updated every 5 minutes with new advisories, which might warn about weather such as thunderstorms, tornadoes, floods, tropical storms, wind, and winter weather. A warning is the most urgent type of advisory, followed by watch, and then advisory. A warning means that severe weather has been spotted in your area or is imminent. A watch or advisory means that you should be on the lookout for inclement weather. You can get advisories, satellite, radar and lightning maps at street level in AccuWeather.com RadarPlus.
