Western Washington Weather Brings Lots of Rain, Flooding and Mudslides

WEATHER SUMMARY

Tuesday’s weather has been a very soggy day bringing lots of rain with some reporting up to 2″ in some places, causing flooding and mudslides in Western Washington State.  Already saturated by rains in the last few days, more began dumping today and not letting up until later this afternoon.

By then, areas like Kent reported large flooded areas and some drivers ignoring common sense and trying to “drive” [we call it boating] across large bodies of water that seemed more like a big swimming hole.
