... The Flood Advisory remains in effect until 630 PM MDT Tuesday for
extreme west central Big Horn and southwestern Yellowstone
Four or more inches of rain has fallen since Saturday morning along
the northern slopes of the Pryor Mountains. This rainfall will cause
rises on Pryor creek and its tributaries over the next couple of
days. Some minor lowland flooding is possible along Pryor creek from
the town of Pryor to its confluence with the Yellowstone river at
Heavy rainfall over the last few days will also cause rises on Blue
Creek in southwestern Yellowstone County. Minor flooding is possible.
Up to an additional inch of rain is possible today. Residents in
these areas are urged to prepare for rising water levels.
Most flood deaths occur in automobiles. Never drive your vehicle into
areas where the water covers the roadway. Flood waters are usually
deeper than they appear. Just one foot of flowing water is powerful
enough to sweep vehicles off the Road. When encountering flooded
roads make the smart choice... turn around... dont drown.
