2 Cooperative Observer
"I’ll never
again see
clouds
with an
artist’s eye.
Now I see
cumulus,
cirrus or
stratus.”

When a select group of volunteers gathered
in the Yucca Valley of California recently, they
identied each other by elevation.
The confab was the annual gathering
of participants in the Morongo Basin’s
Cooperative Observer Program, a partnership
between the National Weather Service and
citizen volunteers.
The group met with Donald Maker, the
program’s manager, to discuss issues and get
updates about procedures.
Attending were volunteers from the width
and breadth of the Basin, from Morongo Valley
to Wonder Valley and from Johnson Valley to
Joshua Tree.
Theresa Langlois, el. 1376 (Wonder
Valley), has been a weather Observer since
2008. Each morning at 9 a.m.,“without fail,”
she gathers data and reports to the NWS in
Las Vegas.
Using equipment installed by the NWS,
Langlois assiduously records the daily
temperature and any precipitation that may
have fallen at elevation 1376. She was trained
onsite by Maker, as were all the volunteers.
Langlois, an artist who has lived in
Wonder Valley for 18 years, loves the beauty
and solitude of the desert and is an active
volunteer in the community. In addition to
her weather work, she serves on the Wonder
Valley Advisory Commission.
“I love weather, nature, animals … not too
crazy about people,” she admits with a smile.
Langlois also volunteers as a certied
weather Spotter, a different job than observing.
Spotters watch for weather events such as
tornadoes, and immediately alert the NWS
to potentially hazardous conditions.
“We learn to read clouds as part of the
training. Certain types of clouds you’d report
on right away,” she says, peering into the
distance. “I’ll never again see clouds with
an artist’s eye. Now I see cumulus, cirrus or
stratus.”
Langlois says the most amazing weather
phenomenon she reported to the Weather
Service was a massive sandstorm that
decreased visibility to zero.
“It was moving east and it got higher and
higher and it was big,” she recalls. “I knew
it was going to hit Highway 62 and affect
visibility, and it was important for them to
know.”
Spotters are obligated to report any critical
weather, especially high winds and flash
ooding. “The Basin is diverse in its weather,”
Langlois comments.
Maker agrees, saying, “The Morongo
Basin is a high-desert region with numerous
elevation changes in a fairly short span. This
creates a challenge to forecasters because the
Basin is not covered well by Doppler Radar.”
Until 2003, the NWS forecast ofces in Las
Vegas and San Diego shared responsibility
for Basin weather statements. The NWS Las
Vegas took over after ofcials decided one
ofce should handle all of those duties.
