RESERVOIR CONDITIONS... Reservoir storage is ample across the
Ohio Valley with most reservoirs near winter pool levels.

OHIO RIVER FLOWS... Observed Ohio River streamflows are above
normal due to a recent heavy rain event but will be trending back
toward normal fairly quickly within the next week.

normal and below 100% equaling below normal.

melt.

ICE COVER... Much of the ice has broken up and gone away due to
the recent warmup. Ice is not a factor in flood potential in the
next several weeks.

2-WEEK AND 90-DAY FUTURE RAINFALL AND FLOOD OUTLOOK SUMMARY...
The two-week outlook calls for near or to slightly below normal
precipitation, generally 1-2 inches with some areas slightly above
or below this. Therefore, with a lack of snow and ice across the
region, flood potential is at or below normal due to new
precipitation the next two weeks.

OHIO RIVER AVERAGE FLOW FORECASTS THE NEXT 2 WEEKS...
The Ohio River flow forecasts are expected to return toward
normal the next two weeks with a lack of a heavy rain event.

Values are in percent of normal with above 100% are above normal
and below 100% are below normal.

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.

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.
