Hydrologic Outlook
National Weather Service Indianapolis IN
136 PM EDT Sun Mar 30 2025
...River Flooding Likely This Week...
Multiple rounds of moderate to heavy rainfall over the next week
will bring the potential for widespread flooding to central
Indiana. Rainfall amounts of 1.5 to well over three inches are
forecast for the next seven days from multiple systems passing
through the Ohio valley. Rainfall with the storm systems this
weekend will serve to saturate soils and raise river levels, and
could result in the development of some minor lowland river
flooding early in the week. Another mid-week system bringing
heavy rainfall into these already saturated basins is likely to
produce widespread minor river flooding and has the potential to
bring moderate flooding to the area as well. Those with interests
along area rivers should monitor forecast updates through the
weekend and into next week for the latest information.
