At 420 PM MDT, Doppler radar was tracking a strong thunderstorm 8
miles north of Pritchett, or 15 miles northwest of Springfield, 
moving south at 15 mph. Persistent moderate to heavy rain has been 
falling over the region. Some personal weather stations have picked 
up around .7" of rain in the past hour. This will make local roads 
potentially hazardous to travel on with road ponding expected or 
gravel roads being overly saturated. Drainages in the vicinity may 
be running high too.

Locations impacted include...
Pritchett.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

Torrential rainfall is also occurring with this storm, and may lead
to localized flooding. Do not drive your vehicle through flooded
roadways.
