Weather: HYDROLOGIC OUTLOOK: Rises on Small Streams And Main-Stem Rivers Through The Week

HYDROLOGIC OUTLOOK

Rises on small streams and main-stem rivers through the week.

North-central Washington: The combination of snow melt and rain showers through mid-week will continue rises on area rivers and streams. Some rivers have the potential of reaching bank-full, while others like the Okanogan and the Kettle will experience minor flooding.

East slopes of the northern Cascades: Rain showers will return today with heavy down pours and a thunderstorm possible this afternoon into the early evening. Steep slopes and burn scars will be susceptible to localized flooding with any heavy rainfall.

Northeast Washington and the northern Idaho Panhandle: Rain showers with embedded afternoon thunderstorms are expected today. Heavy down pours are possible, which may lead to localized flooding in steep terrain. Moderate rainfall is expected overnight into Wednesday, especially in north Idaho. This coupled with high mountain snow melt will lead to rises on small streams and main-stem rivers. Several rivers are expected to reach bank full conditions by mid to late week.

Southeast Washington and the southern Idaho PanhandLe: Scattered rain showers will become more widespread this evening. Bands of moderate to heavy rain are likely overnight and through Wednesday evening. The excessive rainfall will likely produce sharp rises on streams and main-stem rivers into the area. Many rivers are expected to reach bank full by mid to late week. Localized flooding and mud slides are possible especially in steep slopes.

Please continue to monitor river products for the latest forecasts this week.
