NATIONAL WEATHER SERVICE PHOENIX ARIZONA
517 AM MST SAT JUL 14 1990

THE NATIONAL WEATHER SERVICE IN PHOENIX ARIZONA HAS ISSUED A
FLASH FLOOD WARNING EFFECTIVE UNTIL  900 AM MST
FOR THE FOLLOWING LOCATIONS.

IN NORTHEAST ARIZONA

   ...SOUTHERN APACHE COUNTY...SOUTHERN NAVAJO COUNTY

THE FLASH FLOOD WARNING ISSUED EARLIER FOR THE PUERCO RIVER LOCATED IN
SOUTHERN NAVAJO AND SOUTHERN APACHE COUNTIES IN NORTHEAST ARIZONA HAS
BEEN EXTENDED TO 9AM.


HEAVY RAINS OVER THE HEADWATERS OF THE PUERCO RIVER IN NEW MEXICO
FRIDAY EVENING CAUSED A TREMENDOUS VOLUME OF WATER TO FLOW INTO THE
ARIZONA SIDE OF THE PUERCO OVERNIGHT.

BETWEEN 1 AND 2 AM THE PUERCO RIVER AT SANDERS PORT OF ENTRY OVERFLOWED
ITS BANKS AND THREATENED TO WASH OUT THE LARGE HIGHWAY 666 BRIDGE.  IT
DIDNT.  THE RIVER LEVEL AT SANDERS HAS SINCE FALLEN.

HOWEVER HIGHWAY PATROL OFFICERS AT THE SMALL HAMLET OF NAVAJO...
ON INTERSTATE 40 ABOUT 14 MILES WEST OF SANDERS... REPORTED A 12 FOOT
WALL OF WATER... WELL WITHIN THE BANKS OF THE PUERCO... MOVING
DOWNSTREAM AT 10 MPH.  PARTROL OFFICERS ALSO REPORTED THE WALL OF WATER
APPEARED TO BE MOVING IN SLOW MOTION.  THIS WAS DUE TO THE GENTLE SLOPE
OF THE PUERCO RIVER.

THE 12 FOOT CREST IS EXPECTED TO BE CONTAINED WITHIN THE RIVER BANKS
BEFORE IT REACHES THE CONFLUENCE OF THE LITTLE COLORADO RIVER AT
HOLBROOK BETWEEN 8 AND 9AM.

THE FLASH FLOOD WARNING APPLIES TO THOSE PERSONS ATTEMPTING TO CROSS
AT UNBRIDGED RIVER CROSSINGS... OR THOSE WHO ARE CAMPED AND SLEEPING
IN THE RIVER BOTTOM DOWNSTREAM AHEAD OF THE 12 FOOT WALL OF WATER.
