Another round of moderate to heavy rain will occur in the Friday afternoon through Saturday time frame. The anticipated runoff from this upcoming event will likely produce small stream flooding as well as field flooding. Additional rainfall is also likely to significantly increase the risk for mudslides.
Our unusually wet and snowy winter has raised the water table unusually high over north Idaho and a large portion of Washington. Flooding is ongoing in many areas and any additional rain will likely make conditions worse.
In addition to small stream and field flooding, several rivers in North Idaho and eastern Washington are rising as melting snow works through the system.
Look for rain to spread over eastern Washington and north Idaho Friday afternoon and increase Friday night and Saturday morning. Drier and cooler conditions are expected Sunday and Monday, but another mild and wet pattern will likely develop Tuesday and continue into next weekend. Flooding has the potential to be a concern in the Inland Northwest for more than a week.
