PORTLAND, Ore. (KOIN) — An Urban Flood/Small Stream Advisory has been issued by the National Weather Service for Portland and Vancouver.

This comes as a strong fall storm is expected to continue to bring five more hours of moderate to heavy rain Sunday.

The National Weather Service calls for small stream flood and minor flooding of poor drainage areas in the Northwest Oregon areas of northwestern Clackamas County, southeastern Washington County, western Multnomah County and the Southwest Washington area of southwestern Clark County.

The advisory continues until 9:30 p.m. As of 4:30 p.m., there have been quite a few reports of standing water on streets and roadways across the Portland and Vancouver area — mainly “main due to poor drainage or clogged drains,” the NWS reported.

“A strong front will move into the area later this afternoon and evening, bringing another surge of heavy rainfall — similar to what the area received Saturday,” according to the NWS Sunday. “The heaviest rain is expected with the front between 6 p.m. and 9 p.m. this evening. Rainfall rates of two-tenths to three-tenths of an inch per hour is possible as the front moves across the area this evening.”

On Sunday afternoon September 2013 became the wettest September on record at the Portland International Airport weather station.

As of 3 p.m. the weather station measured 4.62 inches of rain so far for the month, according to the National Weather Service. That measurement surpasses the old record of 4.3 inches set in 1986.

More rain is expected Sunday night and Monday — fully blowing the old record out of the water.

Portland also broke Sept. 28′s record for rainfall, with 1.25 inches. Salem and Astoria also broke Sept. 28′s rainfall records.
