Hydrologic Outlook issued March 24 at 11:31AM MDT by NWS Missoula MT

Summary: ESFMSO Lincoln, Sanders and Mineral Counties Moderate rainfall is expected to continue across the region through Wednesday morning.

Widespread flooding is not anticipated at this time. However, those living near waterways or in areas prone to nuisance flooding should monitor the situation.
