The Weather Prediction Center (located in College Park, Maryland) is part of the National Centers for Environmental Prediction (NCEP). NCEP is one of the offices that is associated with the National Weather Service (NWS).
One of the responsibilities of the WPC is to issue forecast outlooks for excessive rainfall. Similar to Convective Outlooks issued by the Storm Prediction Center (more details by clicking here).
“In the Excessive Rainfall Outlooks, the WPC forecasts the probability that rainfall will exceed flash flood guidance within 25 miles (40 kilometers)” (Weather Prediction Center).
|Level||Risk Category||Probability of Rainfall Exceeding Flash Flood Guidance|
|1 (Green)||Marginal (MRGL)||5-10%|
|2 (Yellow)||Slight (SLGT)||10-20%|
|3 (Red)||Moderate (MDT)||20-50%|
|4 (Pink)||High (HIGH)||>50%|
Remember, if you ever come across any flood waters while driving, TURN AROUND, DON’T DROWN.
