...THE FLASH FLOOD WARNING REMAINS IN EFFECT UNTIL 700 PM MDT FOR
NORTHEASTERN TELLER AND WEST CENTRAL EL PASO COUNTIES...

At 430 PM MDT, trained weather spotters reported thunderstorms 
producing heavy rain in the Manitou springs through Chipta Park 
areas. Up to two inches of rain have already fallen between Woodland 
Park area and Cascade along highway 24.  Flooding of Fountain Creek 
will continue in these areas and will drain through Manitou Springs 
and Colorado Springs. Flash flooding is expected to continue.  Get 
away from the banks of Fountain Creek.  

Excessive rainfall over the burn scar will result in debris flow 
moving through the drainages along the southern and western portions 
of the burn scar.  The debris flow can consist of rock, mud, 
vegetation and other loose materials.

Some locations that will experience flooding include...
Colorado Springs, Woodland Park, Air Force Academy, Manitou Springs,
Green Mountain Falls, Pikes Peak, Crystola, Chipita Park and Cascade.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

Turn around, don't drown when encountering flooded roads. Most flood
deaths occur in vehicles.

Move away from recently burned areas. Life-threatening flooding of
creeks, roads and normally dry arroyos is likely. The heavy rains
will likely trigger rockslides, mudslides and debris flows in steep
terrain, especially in and around these areas.

...THE FLASH FLOOD WARNING REMAINS IN EFFECT UNTIL 700 PM MDT FOR
NORTHEASTERN TELLER AND WEST CENTRAL EL PASO COUNTIES...

At 514 PM MDT, trained weather spotters reported thunderstorms which 
produced heavy rain along highway 24 between Woodland Park through 
the southwest side of Colorado Springs. Up to two inches of rain has 
fallen in this area. Storms have moved out of the warning area...but 
flash flooding is expected to continue until the water has a chance 
to recede.

Excessive rainfall over the warned area has caused mud slides 
across portions of highway 94 between mile markers 288 and 297. 
Highway 24 was reported closed at 452 PM. Mud slides can consist of 
rock, mud, vegetation and other loose materials.

Some locations that will experience flooding include...
Colorado Springs, Woodland Park, Air Force Academy, Manitou Springs,
Green Mountain Falls, Pikes Peak, Crystola, Chipita Park and Cascade.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

Turn around, don't drown when encountering flooded roads. Most flood
deaths occur in vehicles.

Remain alert for flooding even in locations not receiving rain.
Arroyos, streams, and rivers can become raging killer currents in a
matter of minutes, even from distant rainfall.

Move away from recently burned areas. Life-threatening flooding of
creeks, roads and normally dry arroyos is likely. The heavy rains
will likely trigger rockslides, mudslides and debris flows in steep
terrain, especially in and around these areas.
