FLOOD STATEMENT
NATIONAL WEATHER SERVICE BISMARCK ND
824 PM CST SUN MAR 2 2025
.WARM WEATHER HAS PRODUCED ENOUGH RUNOFF INTO THE YELLOWSTONE RIVER
TO CAUSE IT TO RISE AND PRODUCE ICE JAMS IN MONTANA FROM NEAR MILES
CITY TO SIDNEY. THIS RISING WATER WILL CONTINUE TO MOVE DOWNSTREAM
AND MAY ALSO BREAK UP THE ICE ON THE YELLOWSTONE AND MISSOURI RIVERS
WEST OF WILLISTON IN NORTH DAKOTA. AS THE ICE BREAKS UP IN NORTH
DAKOTA, THE RISK OF WATER LEVELS RISING ALONG THE YELLOWSTONE AND
MISSOURI RIVERS WILL INCREASE AS ICE BLOCKAGES OCCUR, BUT THE
PERIODS OF HIGH WATER SHOULD BE RELATIVELY BRIEF AND SELF RESOLVING.
NONETHELESS, THOSE LIVING ALONG THE RIVER AND OTHER INTERESTS ON THE
FLOOD PLAINS SHOULD BE DILIGENT OF RAPIDLY CHANGING RIVER CONDITIONS.
