... Flash Flood Watch remains in effect through this evening...

The Flash Flood Watch continues for

* portions of northwest South Dakota... southwest South Dakota
and west central South Dakota... including the following
areas... in northwest South Dakota... northern foot hills. In
southwest South Dakota... Bennett... Custer co plains... Fall
River... Hermosa foot hills... Jackson... Shannon... southern
Black Hills and southern foot hills. In west central South
Dakota... central Black Hills... Haakon... northern Black Hills...
Pennington co plains... Rapid City... southern Meade co plains
and Sturgis/Piedmont foot hills.

* Through this evening

* scattered thunderstorms that occur this afternoon and evening
have the potential to be slow moving and produce locally heavy
rainfall. The greatest chance for flash flooding appears to be
across southern South Dakota. However... some areas in the Black
Hills through central South Dakota received heavy rains
overnight and this morning... so any additional rainfall this
afternoon and evening could produce flash flooding in those
areas as well. The threat for flash flooding is expected to end
by midnight.

Precautionary/preparedness actions...

A Flash Flood Watch means that conditions are favorable for heavy
rain over the watch area... which may cause flash flooding along
streams... creeks... canyons... and draws. If you are in the watch
area... monitor NOAA Weather Radio and local media for updated
forecasts. Be ready to quickly move to higher ground... if heavy
rain occurs... rising water levels are observed... or a warning is
issued.
