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

.DAY ONE...This Afternoon and Tonight

Upper low pressure and monsoon moisture, will interact to bring
an uptick in thunderstorm activity today. The most widespread
activity will be over the southern and western mountain areas,
including the Spring Fire scar. Primary storm concerns today will
be lightning, wind gusts to around 40 mph and locally heavy rain.
Rainfall may be heavy enough to cause flash flooding on area burn
scars. This would include the Spring and Chateau burn scars as
well as older ones such as the Junkins and Hayden Pass scars.

.DAYS TWO THROUGH SEVEN...Thursday through Tuesday

Monsoon moisture will continue to increase for Thursday and Friday
bringing the potential for heavy rainfall from slow moving
thunderstorms, across much of southern Colorado. This will bring
the risk for flash flooding on active and recent burn scars,
particularly Spring, Hayden Pass and Junkins. This threat may
spread northward to include the Chateau burn scar on Friday. A
moist pattern will continue into early next week with scattered
thunderstorms possible each day, particularly across the
mountains. Sunday may see another elevated flash flood threat for
area burn scars.

.SPOTTER INFORMATION STATEMENT...

Weather conditions that meet reporting criteria for spotters will be
possible this afternoon and evening in or near area burn scars.
