A flood watch has been issued for several rivers on Puget Sound, including the Snoqualmie River, as a rain system moves across the region.

Areas near the Cascade Mountains could see flooding in King and Snohomish counties, said Carly Kovacik, a Seattle National Weather Service meteorologist. While the flooding is expected to be minor, people should pay attention to river gauge levels.

“The water may breach the banks of those rivers and cause minor impacts, but in terms of widespread damage or widespread flooding, that’s not likely or expected from this event,” Kovacik said.

Between 2 to 4 inches of rain could fall on areas of the mountains or along the coast as a frontal system pushes through today and overnight. It should clear up by tomorrow morning before the area dries out through Thursday.

River gauges on the Snoqualmie River near Carnation and Snoqualmie predicted the river would reach flood stages overnight, as of Monday afternoon. However, Snoqualmie Fire Department administrative coordinator Tom Munroe said they didn’t expect much flooding in town.

“At this stage we aren’t expecting anything, it’s not like we’re going to have to get people out doing sandbags,” he said.

Some lowland areas might see some flooding, or the city’s bridge leading to the dog park. Munroe said the gauge predictions were likely overstating the flooding potential.

However, if rain is heavier than expected, and flooding becomes more likely, the city will issue warnings and could activate its emergency command center.

Other rivers which could see flooding include the Tolt, the Stillaguamish, Skykomish and Snohomish in Snohomish County, and the Calawah and Bogachiel in Clallam County.
