NATIONAL WEATHER SERVICE GRAND FORKS ND
129 PM CDT THU MAY 16 2013

...PROLONGED RAINY PERIOD EXPECTED INTO EARLY NEXT WEEK...

THE RED RIVER BASIN IS EXPECTED TO EXPERIENCE A PROLONGED PERIOD
OF RAINFALL BEGINNING THIS EVENING AND CONTINUING INTO TUESDAY.
ALTHOUGH IT WILL NOT RAIN CONTINUOUSLY DURING THIS ENTIRE
PERIOD...THE CUMULATIVE RAINFALL AMOUNTS ARE EXPECTED TO RANGE
FROM 2 TO 4 INCHES...WITH LOCALLY HIGHER AMOUNTS POSSIBLE IN AREAS
EXPERIENCING REPEATED THUNDERSTORMS.

THE HEAVIEST PRECIPITATION AMOUNTS ARE EXPECTED OVER THE WEEKEND
DURING THE SATURDAY INTO SUNDAY TIME PERIOD. MODERATE RAINFALL
RATES ARE EXPECTED FROM THUNDERSTORMS OVER THE WEEKEND WHEN
ATMOSPHERIC MOISTURE WILL BE AT ITS HIGHEST. LOCALIZED FLASH
FLOODING WILL BE POSSIBLE IF THUNDERSTORMS PRODUCING HEAVY
RAINFALL REPEATEDLY MOVE OVER THE SAME AREA.

SOILS ACROSS THE AREA HAVE DRIED OUT TO A CERTAIN EXTENT AND WILL
BE ABLE TO ABSORB SOME OF THE PRECIPITATION. HOWEVER...ENOUGH
RAINFALL IS EXPECTED DURING THAT SOME SMALLER RIVER BASINS MAY
RISE ABOVE FLOOD STAGE NEXT WEEK AS RUNOFF WORKS ITS WAY INTO THE
RIVER SYSTEM.

LOOK FOR ADDITIONAL STATEMENTS AND FORECASTS ON THIS DEVELOPING
HYDROLOGICAL SITUATION.
