Watches & Warnings

Flash Flood Watch
Issued: 3:21 PM CDT Jul. 26, 2017 – National Weather Service

... Flash Flood Watch remains in effect through late tonight...

The Flash Flood Watch continues for

* portions of south central Iowa, southeast Iowa, and southwest
Iowa, including the following areas, in south central Iowa,
Appanoose, Clarke, Decatur, Lucas, Monroe, Ringgold, Union,
and Wayne. In southeast Iowa, Davis and Wapello. In southwest
Iowa, Adams and Taylor.

* Through late tonight

* a cold front will continue to slowly makes it's way through the
state but slow as it approaches southern Iowa. Thunderstorms are
expected along and ahead of the frontal boundary tonight.
Moisture in the atmosphere is abundant and to a fairly extensive
depth in the atmosphere and as a result, any storms that develop
will be efficient at producing heavy rainfall. Rainfall rates of
2-3 inches per hour are possible, along with training of storms,
which means that it is possible for a number of storms pass over
the same location, each of which could produce heavy rainfall.
Although conditions are still relatively dry in the watch area,
the intense rainfall rates may lead to flash flooding,
especially in urban areas and low lying areas because the ground
is hard and rapid or heavy rainfall will only runoff instead of
soaking into the ground.

Precautionary/preparedness actions...

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.
