the evening, thunderstorms with locally heavy rainfall will move
across northeast and central Iowa.

in localized flash flooding across the watch area. Rainfall
rates may exceed 2 inches per hour at times.

...Heavy Rain Today And Tonight...Elevated Flooding Risk...

Heavy rain is likely later today through tonight as another round
of showers and thunderstorms move through the area. The bulk of
the heavy rain is expected to fall from southeast Minnesota into
northwest Wisconsin. Amounts from 2 to 6 inches are anticipated,
with locally higher possible. Localized flooding should be
planned for with the potential for more widespread flooding to
develop. Rapid rises on rivers and creeks and other drainage areas
will also occur, leading to an additional flooding threat.

Southeast of La Crosse amounts are expected to be less, but
northeast Iowa and southwest Wisconsin have already experience
several inches of rain over the past week. Any additional rainfall
will likely result in more flooding - possibly life threatening.

This is a potentially dangerous situation, especially in those
locations that are currently, or have recently had heavy rain and
flooding. The time to prepare is now. Do not wait until heavy rain
or flooding is occurring.

higher possible. Localized to widespread flooding is possible.

your area. NEVER cross a flooded road.


A Flash Flood Watch means that conditions may develop that lead
to flash flooding. Flash flooding is a very dangerous situation.

You should monitor later forecasts and be prepared to take action
should Flash Flood Warnings be issued.
