HYDROLOGIC OUTLOOK
NATIONAL WEATHER SERVICE GRAND FORKS ND
1258 PM CDT FRI MAY 17 2013

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

THE RED RIVER BASIN IS EXPECTED TO EXPERIENCE A PROLONGED PERIOD
OF RAINFALL THIS WEEKEND INTO EARLY NEXT WEEK. 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 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.
