Public Information Statement

Statement as of 11:53 PM PDT on September 02, 2015

... Warmth for all but no so with rain in August...

August 2015 will go down as one of the warmest augusts on record in
the Mojave Desert and southern Great Basin. For much of the month,
high pressure aloft was either centered over the area or just to the
east, keeping the area in a warm south to southwest flow. At the
same time, this pattern largely limited the pushes of monsoon
moisture into the area compared to July. As a result, shower and
thunderstorm activity was not as extensive this month. A few areas
saw no precipitation at all.

Another characteristic of August was the smoke and haze caused by
wildfires mainly in northern and central California. Lofted smoke
and haze frequently impacted the Owens Valley of California. Haze
reduced visibility below 6 miles in Bishop on 11 days during the
month. Lofted smoke and haze from northern California and the
Pacific northwest drifted into much of Lincoln and Clark counties in
Nevada from the 19th into the 22nd. The Willow fire was first
reported in Mohave County, Arizona on the 8th and burned 5,976
before being listed as 100 percent contained on August 17th. A total
of 11 structures and 7 RV trailers burned from the fire.

The hottest period of the month was generally between the 14th and
18th when all locations set their highest readings of the month. The
coolest weather of the month was between the 5th and 9th as a series
of two upper level troughs moved across California and Nevada. Just
about all locations set their lowest reading of the month then.

Monsoon moisture that had worked into the area in late July lasted
through August 2nd. On August 1st, thunderstorms developed over the
White Mountains of California resulting in flash flooding in The
Narrows area of Highway 168. Later that day, thunderstorms moved in
Dyer, Nevada and dropped a total of 3.07 inches of rain between 4
and 9 PM. This established a new all-time 24 hour precipitation
record for Dyer. The previous record was 2.05 inches on August 9th
and 10th in 1983. Records at Dyer date back to 1903. Flooding took
place on Highway 264 in Dyer as a result.

Showers and thunderstorms returned to the area on the 6th and 7th.
Several reports of gusts of 58 mph or greater were reported on the
afternoon and evening of the 6th, including a gust of 58 mph at the
Boulder City, Nevada Airport and 67 mph at a mesonet station
southeast of Littlefield, Arizona. Several roads were reported on
the 7th in Lincoln, Clark and Mohave counties. An automated Guage on
upper Diamond Bar Road in Mohave County measured 4.76 inches of rain
between 5 PM on August 6th and 8 am on August 7th. Storms quieted
down on the 8th but returned on the 9th.

The next active period for the monsoon lasted from the 11th through
the 14th. Thunderstorms impacted Clark and Lincoln counties and
Mohave County on the afternoon and evening of the 13th. Again,
several roads were flooded. Overton, Nevada received hail and
clocked a 59 mph wind gust from a thunderstorm. On the evening of
the 14th, a thunderstorm developed near the Willow fire and lofted
ash and soot from the fire into a wall of dust that traveled as far
north as the Laughlin-Bullhead City area. Visibility dropped to or
below a quarter of a mile as the wall of dust moved through.

Another push of monsoon moisture arrived on the 25th and lasted
through the 27th. Thunderstorms kicked up dust near Dolan Springs,
Arizona on the 25th reducing visibility. On the 26th, a strong
thunderstorm developed over Joshua Tree National Park in California
and moved northeast unleashing heavy rain on Twentynine Palms. This
resulted in several roads flooding, including Highway 62, with one
Swiftwater Rescue reported. Storms that day also flooded roads in
parts of Lincoln County. Showers and thunderstorms also developed on
the 29th but no noteworthy impacts were reported.

* notable events during the month:

This August tied with 1994 for the 4th warmest August on record
based on the average temperature of 92.9 degrees. The warmest August
ever was not all that long ago in 2011 when the average temperature
was 93.9 degrees. The warmth this August was a combination of the
very warm low temperatures but also above average high temperatures.

There were a total of 23 days this August with a low of 80 degrees
or greater. This ties 2008 and 2011 for the second highest such
total ever in August in Las Vegas. The highest number of such
days for August is 25 set in 2012. The normal number is 12 days.

There were a total of 27 days with a triple digit high this August
which was 6 days above normal. This was the highest total for August
since 2011 when there were 30 such days.

The average wind speed of 7.1 mph made this the least windiest
August since 2009 when the average was 6.6 mph.

The outstanding event of the month was the series of showers and
thunderstorms that impacted the southeast and east-central parts of
the Las Vegas Valley on the afternoon of the 13th. Rainfall totals
of a half an inch to well over an inch fell in a span of 30 minutes
to a little over an hour resulting in numerous streets flooding in
Henderson. Mud and rocks washed onto several roads including Horizon
Ridge Parkway which resulted in Road closures. Several streets had
minor flooding as well in downtown Las Vegas. Thunderstorm wind
gusts were measured over 60 mph in parts of the valley. The highest
measured gust was 62 mph near Craig and Donner by a spotter. The
winds were powerful enough to knock down 27 wooden power poles near
Lake Mead Parkway and Warm Springs. At least 10,800 NV energy
customers lost power in the Las Vegas Valley with prolonged outages
in areas where the power poles were knocked down. In the same area,
several homes lost roof shingles, had fences knocked down and trees
toppled. A large metal billboard in southeast Henderson was

There was at least one confirmed heat-related death in Las Vegas on
August 11th when an 84 year old Australian tourist was found dead
near the McCarran Airport connector Road Tunnel. The death was ruled
a combination of a weakened and enlarged heart, senile dementia and
environmental heat stress by the Clark County coroner.

Lofted smoke and haze from wildfires in northern California and the
Pacific northwest reduced visibility in the Las Vegas Valley on the
19th and 20th.
