No flooding so far in annual Wyoming runoff

The annual snowmelt in Wyoming has been uneventful so far with no reports of flooding. But the runoff isn't expected to reach its peak until the first week or 2 of June. National Weather Service hydrologist Jim Fahey says there have been instances of rivers or streams reaching near capacity this spring on the east side of the Bighorn Mountains but no flooding. Fahey says the runoff so far has involved snowpack that had accumulated below 10,000 feet. A warm spell a week ago brought a brief rush of water down from the mountains but cooler temperatures this week slowed the melt. Fahey says the only wild card now is the amount of rain that falls, which can quickly raise rivers and streams already carrying snowmelt water.
