Storm breaks one but not all rainfall records

Overcast weather predicted for next few days.

It's an unofficial Rose Festival tradition - rain fell on the opening weekend of Portland's annual civic festival, creating muddy conditions at the City Fair entertainment center in Tom McCall Waterfront Park that could continue for for much of its run.

Rain is predicted to continue falling in coming days, but nothing like the thunderstorm that swept through Saturday evening. According to KOIN Local 6 weekend weather anchor Sally Showman, it came close to breaking the all time one hour rainfall record at Portland International Airport.

"Portland International Airport picked up 1.02' of rain in one hour. That is only 0.01' less than the all-time one hour rainfall record at PDX," Showman says.

The daily record was broken, however, with a total of 1.03 inches of rainfall being recorded at the airport compared to .93 inches in 1953.

There were reports of sporadic standing water and flooding across Vancouver and Portland as a result of the storm. Portland's combined sewers also overflowed from two outfall pipes, one on the Willamette River just south of the St. Johns Bridge and one on the Columbia Slough at North Oswego Avenue about a half mile west of North Portland Road near the Smith and Bybee Wetlands. The Bureau of Environmental Services advised the public to avoid contact with the water at those locations today and tomorrow.

The airport also experienced two rain-related problems. The first was a pool of standing water, estimated at one inch deep and approximately 20 feet in diameter, on the baggage road in a secured area of the airport. A second leak prompted staff to place buckets to capture water in the "pedestrian tunnel." Neither problem delayed air travel.

In addition, Portland Timber's fans ran for cover as pouring rain and lightning delayed the Saturday evening game against the Vancouver Whitecaps. The delay lasted about 20 minutes. After the storm passed, a time lapse of lightning was shown on the large electronic scoreboard.

Both Sunday and Monday are expected to be overcast with occasional sprinkles.
