-Storm Prediction Center (SPC)+======Storm Prediction Center (SPC)====== 
 +The Storm Prediction Center is a branch of the NWS and provides data to the public about severe weather as well as other hazardous weather.  
 +===== Severe Weather ===== 
 +The SPC issues probability maps for days 1 through 8, but in different forms. The day 1 always provides the probability of tornadoes, wind, hail, and the risk of severe weather. Days 2 and 3 only provide the risk and probabilistic outlook for any severe weather type. Days 4 through 8 provide only the probability of severe weather in general. 
 +==== Risk Classifications of Severe Weather ==== 
 +Severe weather is classified by the SPC in 6 ways: 
 +  * General thunderstorms - weak thunderstorms,​ maybe a few with 40mph winds and small hail. 
 +  * Marginal risk - chance of spotty damaging winds, spotty hail up to 1", very low possibly a tornado in the area. 
 +  * Slight risk - medium chance of having high winds of 60mph+, hail greater than 1", low chance of a tornado in the area. 
 +  * Enhanced risk - High chance of high winds 60mph+, hail greater than 1", possibly larger than 2", medium risk of a tornado in the area. 
 +  * Moderate risk - very high chance of high winds 60mph+, hail greater than 1", possibly larger than 3", very high risk of a tornado in th area. 
 +  * High risk - reserved for definite tornado outbreaks and derechos. Tornadoes almost definite in the area, including strong, long track varieties, ​ winds greater than 70mph likely.
