FLASH FLOOD WARNING
NATIONAL WEATHER SERVICE PUEBLO CO
427 PM MDT WED JUN 9 2004

THE NATIONAL WEATHER SERVICE IN PUEBLO HAS ISSUED A

* FLASH FLOOD WARNING FOR...
  NORTHWESTERN TELLER COUNTY IN CENTRAL COLORADO

* UNTIL 730 PM MDT

* AT 421 PM MDT...NATIONAL WEATHER SERVICE DOPPLER RADAR INDICATED   
  A THUNDERSTORM PRODUCING HEAVY RAIN HEADING TOWARDS THE HAYMAN     
  BURN SCAR. THIS RAIN WILL BE CAPABLE OF CAUSING FLOODING ACROSS
  THE HAYMAN BURN SCAR AREA IN TELLER COUNTY.

JUST A SMALL AMOUNT OF RAINFALL ON A BURN SCAR CAN LEAD TO FLASH
FLOODING. WATER THAT IS NORMALLY ABSORBED BY VEGETATION...RUNS OFF
ALMOST INSTANTLY. THIS CAUSES CREEKS AND DRAINAGE AREAS TO FLOOD AT A
MUCH FASTER RATE THAN NORMAL. ADDITIONALLY...THE SOILS IN A BURN SCAR
BECOME VERY UNSTABLE WHEN IT RAINS. ENTIRE HILLSIDES CAN BREAK
AWAY...CREATING DEVASTATING ROCK SLIDES...MUDSLIDES...AND DEBRIS
FLOWS. ROADWAYS ARE OFTEN DESTROYED BY THE POWERFUL FORCE OF THE
RUSHING WATER AND DEBRIS...ESPECIALLY IF THEY PASS THROUGH A CREEK
BED OR OTHER DRAINAGE AREA.
