The National Weather Service in Portland has issued an
* Urban and Small Stream Flood Advisory for minor flooding of poor drainage areas in... eastern Washington County in northwest Oregon... eastern Yamhill County in northwest Oregon... northwestern Clackamas County in northwest Oregon... northwestern Marion County in northwest Oregon... western Multnomah County in northwest Oregon... Clark County in southwest Washington...
* until 330 PM PST.
* At 1234 PM PST National Weather Service Doppler radar indicated an area of heavy rain and embedded thunderstorms moving slowly across the Willamette Valley and Clark County lowlands. Heavy rain is expected to continue over the next hour... possibly longer. A National Weather Service employee has reported that this rain is already causing localized minor street flooding in the city of Portland.
A few locations impacted include Battle Ground... Vancouver downtown... Washougal... Hillsboro... Oregon City and Portland downtown.
Precautionary/preparedness actions...
Additional rainfall amounts of up to 1 inch are possible in the warned area. This will exacerbate ponding on roadways and will likely cause localized minor street flooding... especially in areas with poor drainage due to storm drains being clogged with Leaf debris.
Excessive runoff from heavy rainfall will cause ponding of water on highways... streets and underpasses... in urban areas with poor or overwhelmed drainage... and will also cause elevated levels on small creeks and streams.
