At 118 PM MDT, Doppler radar was tracking a strong thunderstorm 23
miles west of Two Buttes Reservoir, or 31 miles northwest of 
Springfield. This storm was nearly stationary. Heavy rainfall may 
cause hazardous travel conditions due to ponding on roads and lower 
visibilities. Some enhanced streamflow in drainages may be observed. 

This storm will remain over mainly rural areas of northwestern Baca,
northeastern Las Animas and south central Bent Counties.

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.
