Summary: Minor flooding from earlier rainfall continues in parts of Wyoming and Montana.

Gage-heights at six (6) U.S. Geological Survey streamgages on western tributaries to the Missouri River along the Rocky Mountain Front and in central Montana continue to exceed National Weather Service (NWS) minor flood stages. Flood warnings are in effect for areas of northeastern Wyoming and south-central Montana as floodwaters move downstream. Potentially significant flooding is forecast for the Tongue River basin in Montana.

One peak of record was observed. Two ratings were extended at the request of NWS Missouri Basin River Forecast Center. No streamgages were damaged or destroyed. Two crews are completing high-flow and flood discharge measurements today for rating definition and to aid river forecasters.

Cooperators, stakeholders, and the general public are being kept informed by multiple methods including NWSChat, e-mail, and social media.
