* until noon CDT Friday

* at 1158 PM CDT... National Weather Service Doppler radar estimates
and numerous reports of heavy rainfall from 2 to 4 inches across
the area this evening has resulted in ongoing ponding and flooding
of low lying areas. While thunderstorms have become more scattered
late evening... additional storms are expected to develop between
midnight and 2 am which will bring potential for locally an inch
or two rainfall the remainder of the night... which will prolong
the slow drainage effects from the heavy rainfall.

* Rainfall had created flooding of a Railroad underpass along Highway
59 and 60 in Worthington... with reported ponding across much of
Dickinson County.

Precautionary/preparedness actions...

Be especially cautious at night when it is harder to recognize the
dangers of flooding. If flash flooding is observed act quickly. Do
not enter the water. Turn around and move up to higher ground to
escape flood waters. Do not stay in areas subject to flooding when
water begins rising.

... Severe Thunderstorm Watch safety rules...

A Severe Thunderstorm Watch means that conditions are favorable
for the development of severe weather in the designated area.
During a watch there is no cause for immediate concern. You should
go about your normal business... but be on the lookout and keep up
to date on the latest weather developments. Public safety
officials should activate prearranged plans.

A Severe Thunderstorm Warning... on the other hand... means that a
severe thunderstorm has been sighted or indicated by radar. People
in the path of the storm should take immediate action to safeguard
themselves and their family.

Technically speaking... a severe thunderstorm is defined as having
wind gusts which exceed 58 mph and/or hail at least 3/4 inch in
diameter. However... as these storms develop... they can be
accompanied by tornadoes. Listen to NOAA Weather Radio or other
local media to learn if a warning has been issued for your area.
Also... keep a close watch on the thunderstorms as tornadoes can
form quickly. If you see a tornado... move quickly into a basement.
If none is available... seek shelter in a small interior room on
the lowest floor and stay away from outside walls... doors and
windows. In schools... factories or other institutional type
buildings... stay out of auditoriums and gymnasiums.
