The radar

The Elko radar (KLRX), 133 km from the middle of the area, began a volume at 19:21 UTC, the scan nearest the moment this went out.

The archived warnings, watches and discussions in force at that minute are drawn over the scan, this one among them.

Did it verify

Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this flash flood warning while it was in force. That is not proof nothing happened: reports are thin where few people live.

Cow counts a report within 15 km of the polygon while the warning was in force: a tornado for a tornado warning; hail of 1 inch or more, a gust of 58 mph or more or wind damage for a severe thunderstorm warning; a flash flood report for a flash flood warning.

The nearest sounding before it

Reno, NV (KREV), launched 12:00Z, 7.3 hours before the alert went out and 66 km from the middle of its area. This is the routine balloon launch nearest before it, the air the forecaster had in hand, not a measurement taken for the alert.

Flash Flood Warning
National Weather Service Elko NV
1220 PM PDT Thu Aug 13 2026

The National Weather Service in Elko has issued a

* Flash Flood Warning for...
  The New Pass burn scar in...
  Southwestern Lander County in north central Nevada...

* Until 315 PM PDT.

* At 1220 PM PDT, Doppler radar indicated thunderstorms producing 
  heavy rain over the New Pass Burn Scar. Between 0.4 and 0.5 inches 
  of rain has fallen. The expected rainfall rate is 1 to 2 inches in 
  1 hour. Additional rainfall amounts of 1.5 to 2.5 inches are 
  possible in the warned area. Flash flooding is ongoing or expected 
  to begin shortly.

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

  HAZARD...Flash flooding caused by thunderstorms in and around
           the New Pass Burn Scar.

  SOURCE...Radar.

  IMPACT...Flooding of areas in and around the New Pass Burn
           Scar.

* Some locations that will experience flash flooding include...
  mainly rural areas of Southwestern Lander County

PRECAUTIONARY/PREPAREDNESS ACTIONS...

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.

.DISCUSSION...
(Tonight through next Wednesday)

WEATHER PATTERN OVERVIEW: Upper level ridging to the east and
troughing to the west continue to funnel moisture into the Great
Basin area. This will result in continued rounds of showers and
thunderstorms, mainly in central and eastern Nevada today before
expanding to the entire forecast through Thursday. Thursday is
also expected to be the wettest day, with widespread accumulations
of 0.25” and a band of 0.5” to 0.75” shaping up just south of the
US-50 corridor. This has resulted in a Slight (15%) risk of
excessive rainfall for tomorrow and isolated flash flooding is
expected with the strongest cells.

The trough begins to lift to the north on Friday, weakening the
moisture flow for the weekend and mostly cutting off storms,
leaving about a 10% to 20% chance through Sunday. Models remain in
disagreement after Sunday, with the biggest question being the
future of the current monsoon event. The general indication is
still for the monsoon to continue in central Nevada, however the
strength and northern extent of the event still depend on how the
upper ridge behaves over the next few days and into next week. The
current forecast is reflecting the more cut off scenario, with
dry conditions Monday and Tuesday and some isolated showers for
Wednesday.

FORECAST CONFIDENCE & DEVIATIONS: High confidence in showers and
thunderstorms through Friday, with moderate confidence in spatial
extent of the heaviest accumulations. Moderate confidence in a
mostly dry weekend. Low confidence in the forecast after Sunday as
models continue to strongly disagree regarding the upper level
pattern. No changes to NBM forecast.

&&

.AVIATION...

VFR conditions will be predominant at all terminals through
Thursday afternoon though momentary MVFR/IFR conditions are
possible due to TSRA and smoke from area wildfires. -TSRA is
forecast at all terminals through Thursday afternoon.

&&

.FIRE WEATHER...

Continued moisture flow into the Great Basin will
result in several more rounds of showers and thunderstorms. While
this moisture will keep humidity levels elevated and prevent dry-
windy threats, heavy rainfall may pose flooding and debris flow
threats, particularly for the New Pass and Ward fire areas.
Lightning may also be a threat to fire personnel, although
associated rainfall is expected to prevent any new starts from
lightning.
