A four-day storm that brought about 2 inches of rain to Billings will probably ease up on Monday.
According to the National Weather Service in Billings, there's a 40 percent chance of scattered showers through the day and a predicted high of 61 degrees.
The evening brings a 30 percent chance of showers before midnight and a low of around 44 degrees.
With as much as another inch possible in some areas in Yellowstone and Big Horn County, the NWS has issued a flood advisory for the Pryor Creek and Blue Creek areas.
"Four or more inches of rain has fallen since Saturday morning along the northern slopes of the Pryor Mountains," the advisory said. "This rainfall will cause rises on Pryor Creek and its tributaries over the next couple of days. Some minor flooding is possible along Pryor Creek from the town of Pryor to its confluence with the Yellowstone River at Huntley."
Minor flooding is also possible on Blue Creek.
The weather service continued to warn of possible flooding in areas torched by wildfire last summer.
On Sunday, 0.89 inches of rain fell in Billings and anywhere from 1.5 to more than 2 inches fell from Thursday through Sunday in the area.

Tuesday could provide a break from any rain at all, with the NWS predicting a high of 68 degrees and mostly sunny skies. The evening will be partly cloudy and the low will fall to the mid 40s.
There's a slight chance of more storms and showers in the area beginning Wednesday.
