Big Storm Helps Push September Rains Into Oregon Record Books

A big storm on the last weekend of the month helped make for the wettest September on record in many parts of Oregon.

The National Weather Service reports the 6.21 inches recorded through Sunday in downtown Portland was the most since record-keeping began in 1872. The previous record was 5.52 inches in September 1927. At Portland International Airport, where records have been kept since 1940, the total was 5.06 inches, beating the old record of 4.30 inches set in September 1986.

September records also were set in Eugene, 6.16 inches; Salem, 6.63 inches;, Astoria, 10.51 inches;, Hillsboro, 6.10 inches; and McMinnville, 7.58 inches.

The totals were growing as rain continued Monday, but forecasters say the front is blowing east. A windy day is forecast in eastern Oregon.

Mathew Cohen is a meteorologist at the National Weather Service in Portland. He says what the region experienced over the weekend was unusual for this time of the year.

“The fact that the system is so strong this time of year, it is unseasonably strong. This is sort of a type of patter, the type of system, we’d see later on into October and early November. The fact that we’re getting it the end of September is certainly a bit early in the season of a storm of this size and this strength,” Cohen said.

Thousands lost power over the weekend. PGE says only about 8,000 remained without power Monday morning.
