BULLETIN - EAS ACTIVATION REQUESTED
Flash Flood Warning
National Weather Service El Paso Tx/Santa Teresa NM
257 PM MDT Fri Aug 5 2022

The National Weather Service in El Paso Tx/Santa Teresa has extended 
the

* Flash Flood Warning for...
  North Central Grant County in southwestern New Mexico...

* Until 430 PM MDT.

* At 257 PM MDT, Doppler radar indicated thunderstorms producing 
  heavy rain across the warned area. Up to 1.5 inches of rain have 
  fallen. Flash flooding is ongoing or expected to begin shortly.

Excessive rainfall over the burn scar will result in debris flow 
moving through the Black Canyon. The debris flow can consist of 
rock, mud, vegetation and other loose materials.

  HAZARD...Flash flooding caused by thunderstorms.

  SOURCE...Radar.

  IMPACT...Flash flooding of small creeks and streams, urban
           areas, highways, streets and underpasses as well as
           other poor drainage and low-lying areas.

* Some locations that will experience flash flooding include...
  mainly rural areas of North Central Grant County

PRECAUTIONARY/PREPAREDNESS ACTIONS...

This is a life threatening situation. Heavy rainfall will cause 
extensive and severe flash flooding of creeks...streams...and 
ditches in the  Burn Scar. Severe debris flows can also be 
anticipated across roads. Roads and driveways may be washed away in 
places. If you encounter flood waters...climb to safety.

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.

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

.PREV DISCUSSION...353 AM MDT Fri Aug 5 2022...

.SYNOPSIS...
Somewhat drier air will push into areas east of the Rio Grande
generally keeping the focus for thunderstorms with the potential
for localized flooding in western areas. Warm temperatures will
continue to be seen areas east of the Rio Grande accompanying the
drier air. The monsoonal tap of moisture continues to be disrupted
as the meandering upper-high pressure only swirls around trapped
moisture into the area. Moisture content will be near average or
just above average allowing for daily rounds of afternoon
monsoonal thunderstorms. Temperatures will steadily decline a
degree or two each day through much of next week.

&&

.DISCUSSION...
.SHORT TERM...Today and Tonight...
Like last night, ongoing convection should be wrapping up as the the
forecast period begins. We continue to see above average moisture
across the region. The precipitable water value (PW) from last
nights balloon sounding was a little above an inch and this morning
satellite passes indicate slightly higher PW's. The satellites also
indicate that some slightly drier air has moved into the region the
southern part of the area , but that really hasn't slowed ongoing
convection this AM. We will see the convection wrapping up this
morning and clouds will be on the decrease to start the day. Then
later in the morning we will see clouds on the increase, as again
above average high temperatures will combine with abundant moisture
to help fuel scattered mountain and isolated to scattered lowland
thunderstorms this afternoon and evening. Like the last few days, no
clear trigger to get thunderstorms going, so it should be the
typical pattern for the monsoon season, with the mountain
thunderstorms starting first and then the lowlands getting in on the
action in the late afternoon and evening hours. Our high
temperatures this afternoon will run 3 to 5 degrees above average.
El Paso may end its current streak of triple digit days at 4 as
today's high temperature is forecasted to be 99.

Thunderstorms may linger into the overnight ours again, but where
they form and move, will depend a lot on outflow boundaries from
earlier thunderstorms. Low temperatures Saturday morning will run a
few degrees above average.

&&

.LONG TERM...Saturday through Friday...
Upper-high pressure will elongate itself over the central Plains
on Saturday. Drier air will start filtering into areas east of the
Rio Grande with PW values of ~0.9" (below average) and ~1.2"
(above average) for areas out west. Scattered mountain
thunderstorms in the early afternoon will transition to isolated
lowland storms by the early evening. With the higher moisture
content in place for western areas, these locations will have
increased chances for localized flooding. As for eastern areas,
drier air may keep things somewhat quiet, but the drier air could
have the potential to enhance convection. Small hail and gusty
winds may also be seen with thunderstorms Saturday.

Heading into Sunday, the upper-high is fairly stagnant over the
central Plains, but will begin to erode away. Above average
moisture will slosh around the Borderland allowing for another
round of monsoonal thunderstorms areawide with the same
aforementioned hazards as we will see on Saturday. The ridge will
rebuild over the Four Corners region on Monday and will slowly
meander eastward through Friday morning. The work week will
consist of near average or just above average moisture content
from recycled moisture and will continue the pattern of daily
afternoon thunderstorms.

&&

.FIRE WEATHER...
Our low grade monsoon pattern will continue for the next seven days.
Saturday and Sunday may see lower chances for thunderstorms, but
then better rain chances return for the start of next week. Critical
fire weather conditions are not expected through at least the middle
of next week. The winds, away from thunderstorms, will stay well
below critical levels and our min RH's look to stay at or above 15%
for today through next Thursday. Ventilation rates will range from
good to very good for today through the weekend.
