2-WEEK AND 90-DAY FUTURE RAINFALL AND FLOOD OUTLOOK SUMMARY...  
 
THE TWO-WEEK OUTLOOK CALLS FOR NORMAL TO BELOW NORMAL PRECIPITATION AND  
SUBSEQUENT NORMAL TO BELOW NORMAL STREAMFLOWS. WEATHER SYSTEMS  
PASSING THROUGH THE OHIO VALLEY LOOK TO BE QUITE TRANSITORY AND  
SNOWPACK DOESN'T LOOK TO BUILD AT MUCH A SUBSTANTIAL LEVEL.  
CERTAINLY NOTHING AT THIS TIME FOR THE NEXT TWO WEEKS LOOKS WELL  
BEYOND ANY 'TYPICAL' FEBRUARY WEATHER PICTURE.

ADDITIONAL INFORMATION...  
 
FLOOD RISK IS DEFINED AS FOLLOWS:  
BELOW NORMAL - FLOODING WILL BE LIMITED  
NORMAL - MINOR FLOODING IN THE TYPICAL LOCATIONS  
ABOVE NORMAL - WIDESPREAD FLOODING WITH SOME MODERATE OR MAJOR POSSIBLE  
 
WINTER/SPRING FLOOD OUTLOOKS ARE ISSUED WEEKLY BY THE NATIONAL WEATHER  
SERVICE OHIO RIVER FORECAST CENTER DURING WINTER AND EARLY SPRING TO  
SUMMARIZE BASIN HYDROLOGICAL AND METEOROLOGICAL CONDITIONS. IT ALSO  
ASSESSES THE POTENTIAL FOR FLOOD RISK. THE OUTLOOKS ARE BASED ON  
CURRENT AND FORECAST CONDITIONS.  
 
THE OHIO RIVER FORECAST CENTER ALSO ISSUES A 30-90 DAY WATER RESOURCES  
OUTLOOK MONTHLY THROUGHOUT THE YEAR FOR A CONTINUOUS WATER WATCH. THIS  
CAN BE FOUND AT HTTPS://WWW.WEATHER.GOV/OHRFC/WRO .  
 
FACTOR CONSIDERED IN ASSESSING FLOOD POTENTIAL INCLUDE ANTECEDENT  
CONDITIONS, PAST PRECIPITATION, CURRENT STREAMFLOWS AND RESERVOIR LEVELS,  
SOIL MOISTURE, WATER CONTENT IN SNOW COVER, ICE CONDITIONS AND FUTURE  
PRECIPITATION.
