MISSOULA — Rainfall will develop across western Montana Monday and will continue through Friday, May 22nd.

Confidence continues to increase for a period of heavy rainfall to occur Tuesday and Wednesday. While the exact placement of heaviest rainfall remains uncertain, 24-hour precipitation amounts in excess of 1.5 inches are likely.

Excessive rainfall will combine with snowmelt runoff to produce dramatic water level increases and flooding potential in small stream and mainstem rivers from Wednesday onward.

Watch for rapid rises in river levels across the region, with the greatest concerns on the Clark Fork, Flathead, Bitterroot, Clearwater, Yaak, Fisher, and Swan Rivers.

We will continue to monitor this and bring updates as we move through out the week.
