The National Weather Service cautions significant rainfall today could cause flash flooding and overwhelm storm drains, leading to flooded roads.
Most of Western Washington remains under a flood watch through tomorrow evening, with the heaviest rainfall expected later tonight through tomorrow morning, according to the weather service.
It could led to urban and small stream flooding, but actual river flooding is unlikely, according to the NWS.
The 5 a.m. notification indicates also a short period of intense rainfall accompanying thunder storms.
