This November has been one of the top five wettest Novembers on record for Seattle.
"November rainfall through Sunday was 6.83 inches. The normal for the entire month is 6.31," said Maddie Kristell, meteorologist for the National Weather Service (NWS) in Seattle.
Towns that are expecting a lot of rainfall have been ordered to evacuate. A flood warning was issued for Snoqualmie River until Tuesday. The Skagit River and the Bogachiel river are also expected to flood.
Contributing to the flooding and rising water levels is snowmelt. Because of the amount of rain they are receiving, snowy areas are melting off and running into the rivers.
