The National Weather Service’s Portland office issued a flood advisory to remain in effect until 4 p.m. Friday for several areas of the state, including Benton County.

A flood warning that had been in effect specifically for the Marys River in the Philomath area expired on Tuesday. The Marys River crested at 21 feet on Monday with levels slowly falling. As of 1 p.m. Wednesday, the NWS’s Advanced Hydrologic Prediction Service showed the river level at 19.43 feet — just below the 20-foot level considered to be flood stage. The river forecast shows the level continuing to drop in the coming days. 

Under the most recent advisory, small stream flooding caused by excessive rainfall is expected. Minor flooding could occur in low-lying and poor drainage areas and ponding of water is possible in urban and other areas.

The NWS advises motorists to turn around when encountering flooded roads and to be especially cautious at night when it is more difficult to recognize flooding.

Philomath’s weather forecast shows temperatures in the upper 40s on Wednesday with rain continuing to fall. On Thursday, the forecast high is 53 with showers continuing. On Friday, a high of 46 is expected with rain during the morning hours. And this weekend, temperatures should be in the mid to upper 40s with partly cloudy skies.
