...A FLASH FLOOD WARNING REMAINS IN EFFECT UNTIL 745 PM MDT FOR WEST
CENTRAL PUEBLO...EASTERN CUSTER AND NORTH CENTRAL HUERFANO
COUNTIES...

AT 520 PM MDT...NATIONAL WEATHER SERVICE DOPPLER RADAR CONTINUED TO
INDICATE A THUNDERSTORM PRODUCING FLASH FLOODING OVER THE WARNED
AREA.

LOCATIONS IN THE WARNING INCLUDE BUT ARE NOT LIMITED TO WETMORE AND
BEULAH

DOPPLER RADAR ESTIMATES THAT RAIN TOTALS OF UP TO 2.5 INCHES OF RAIN 
HAVE OCCURRED ACROSS THE SAN ISABEL AND BEULAH AREAS.  UP TO AN INCH 
OF RAIN HAS FALLEN ACROSS PORTIONS OF THE MASON GULCH AREA.  WHILE 
THE HEAVIER RAIN HAS MOVED EAST OF THESE AREAS...ADDITIONAL LIGHT TO 
MODERATE RAINFALL OF UP TO .5 INCHES WILL BE POSSIBLE ACROSS MAINLY 
EASTERN PORTIONS OF THE WARNING AREA. 

THIS WATER WILL DRAIN INTO THE HARDSCRABBLE CREEK...MUDDY 
CREEK...WILLIS CREEK AND THE SAINT CHARLES RIVER WHERE HIGH FLOWS 
WILL BE LIKELY. MUD FLOWS MAY OCCUR IN AND NEAR THE MASON GULCH BURN 
SCAR. ROADWAYS AND LOW WATER CROSSING MAY ALSO EXPERIENCE FLASH 
FLOODING THROUGH 745 PM.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

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 UNSTABLE WHEN IT RAINS...RESULTING IN MUD FLOWS AND FALLING
ROCK. ROADWAYS CAN BE WASHED OUT BY THE FORCE OF THE RUSHING WATER.
