BILLINGS, Mont. (AP) — Water levels are dropping on central Montana's flooding Musselshell River but officials warn it could rise again in coming days.

By Tuesday morning, the river level had fallen about 2 feet from Monday night.

National Weather Service forecaster Chauncy Schultz says residents of the region should remain wary after the equivalent of an inch of rain fell Monday and Tuesday in the Roundup area.

Evacuations for some Roundup residents remain in place.

Temperatures are forecast to reach the 50s later this week. That could increase the runoff from melting snow deposited by the latest storm to hit the region.

Gov. Steve Bullock has issued a flood emergency declaration for the entire state. State officials say no calls for assistance have come from local jurisdictions.
