.SHORT TERM...
A CLOSED UPPER LOW CENTERED JUST EAST OF KELP THIS MORNING WILL
SLOWLY TRANSLATE EAST OVER THE NEXT 24H.  ABUNDANT MOISTURE AND
LIFT WILL BE PRESENT OVER THE EASTERN HALF OF THE CWA.  HAVE NOTED
DRY SLOTTING WORKING NORTHEAST ACROSS THE BIG BEND AND DAVIS
MOUNTAINS...AND THIS HAS LIMITED PRECIPITATION WEST OF A MALJAMAR
TO DRYDEN LINE WHILE PROMOTING SCATTERED EMBEDDED TSRA ACROSS THE
PERMIAN BASIN.  WE EXPECT TO SEE REDEVELOPMENT LATER TODAY OVER
SOUTHWESTERN ZONES GIVEN THE COMBINATION OF MOIST UPSLOPE FLOW...COLD
TEMPERATURES ALOFT...AND MARGINAL INSOLATION.  PRECIP WATER OVER 2.5
CM WILL CONTINUE OVER THE CWFA TODAY...AND AS THINGS DONT APPEAR TO
BE CHANGING A WHOLE LOT...THE THREAT OF HEAVY RAINFALL WILL CONTINUE
THROUGH THE NEXT 24H...AND AS ANY ADDITIONAL RAINFALL WILL POSE
PROBLEMS...WE WILL EXTEND THE FLASH FLOOD WATCH FOR THE ENTIRE AREA
THROUGH 28/10Z.

WHAT APPEARS TO BE A WARM CONVEYOR BELT PROCESS WILL CONTINUE OVER
THE EASTERN HALF THIS MORNING...WHILE WESTERN AREAS WILL SEE SOMEWHAT
OF A RESPITE...THUS POPS WILL BE HIGHEST OVER EASTERN ZONES TODAY AND
TONIGHT. TEMPERATURES WILL BE MODULATED BY RAINFALL AND A LACK OF
SIGNIFICANT INSOLATION...AND A PERSISTENCE APPROACH SEEMS PRUDENT AT
THIS TIME. MAN QPF GRIDS ARE REASONABLE...ALTHOUGH WE DID INCREASE
AMOUNTS THIS MORNING GIVEN CURRENT RADAR TRENDS.  PRECIP CHANCES
SHOULD DIMINISH SLIGHTLY TONIGHT AS THE UPPER LOW TRANSLATES OVER
THE AREA AND WEAKENS SOMEWHAT.  HAVE USED A BLEND OF THE GFS AND GFS
MOS FOR WIND AND DEWPOINT GRIDS THROUGH TONIGHT.

.LONG TERM...
EXIGENCIES PRECLUDE METEOROLOGICAL EXAMINATION BEYOND THURSDAY...
CONSEQUENTLY THE PREVIOUS FORECAST WILL BE USED FOR FRIDAY THROUGH
NEXT WEEKEND. THE MODELS APPEAR CONSISTENT IN HOW THEY HANDLE THE
EVOLUTION OF THE AFOREMENTIONED UPPER LOW AS WELL AS THE INCREASED
RIDGING OVER THE CENTRAL PLAINS...THEREBY KEEPING COOL MOIST
SOUTHEASTERLY FLOW OVER THE REGION.  HAVE ADJUSTED POP AND QPF GRIDS
TO REFLECT A BLEND OF THE MODEL QPFS...WHILE A CONSENSUS SOLUTION
WAS USED FOR ALL OTHER GRIDS THROUGH THURSDAY.

Event by event

1 flash flood. Local standard time, as filed.

Flash Flood, Eddy

When: September 27, 5:15 AM MST to 8:00 AM MST
Where: Eddy County, 12 mi NW of Carlsbad
Reported by: TRAINED SPOTTER
Coordinates: 32.472, -104.304 (the zone’s center; the record gives no point)

Although heavy rainfall had temporarily ended over Eddy County, runoff from previous rains over the Guadalupe Mountains resulted in another flood wave that propagated though Dark Canyon Draw. Flash flooding in several Carlsbad neighborhoods resulted. County Road 408, Hidalgo, Radio, and Boyd Streets were all closed in the city's southwest side due to high water.In addition, runoff through Rocky Arroyo made portions of New Mexico State Highway 137 and U.S. Highway 285 briefly impassable.

What these are

Flash Flood: Flooding that begins within six hours of the rain that causes it, or of a dam or levee failure or ice jam release, often with deadly speed.

After NWS Directive 10-1605, the rules offices file Storm Data by.
