This hazardous weather outlook is for portions of central...east
central...south central and southeast Colorado.

.DAY ONE...Today and Tonight

Thunderstorms are expected to occur across the region this afternoon
and evening. Although all areas will see a chance of storms, the
best coverage and heaviest rainfall is expected to occur along the
Colorado and New Mexico border, especially across the Raton Mesa
region.

Similar to the last several days, sufficient monsoon moisture is
over the region, and locally heavy rains will be possible, which
could result in flash flooding over areas with saturated soil
conditions, urban areas, or burn scars. The best chance of flash
flooding will occur across the Spring Burn scar.

The primary threat with thunderstorms today will be locally heavy
rain, wind gusts to 45 to 55 mph and cloud to ground lightning.

.DAYS TWO THROUGH SEVEN...Tuesday through Sunday

The coverage of rain showers and thunderstorms is expected to lessen
for the rest of the week and into the weekend. Scattered to numerous
thunderstorms will remain possible Tuesday through Sunday over the
mountains and mountain valleys, with more isolated storm activity
across the eastern plains, particularly along the I-25 Corridor.

.SPOTTER INFORMATION STATEMENT...

Weather conditions that meet reporting criteria for spotters will
be possible over much of the region, especially over the mountains
and along the Colorado and New Mexico border regions.
