Minor to moderate flooding in some basins in northwestern Wyoming and along Montana's Rocky Mountain Front is occurring as a result of sustained rainfall.

National Weather Service flood stage currently is being exceeded at 12 sites. A new peak of record (64 years inclusive) was recorded at one site on the Wind River in Wyoming. Three ratings are being extended for sites in the Dearborn and Sun River basins in Montana. Planned streamflow measurements will be the largest direct measurements.

One streamgage is offline.

One USGS crew of two will repair a streamgage and make flood measurements in the Dearborn and Sun River basins today.
