The National Weather Service office in Las Vegas has issued a Flash Flood Warning for Lincoln County, Nevada, effective from 12:01 PM until 3:00 PM PDT on Sunday, September 28. A Flash Flood Warning means flooding is happening right now or is expected to begin very soon — this is a step above a watch and calls for immediate caution.
Flash flooding in this part of Nevada typically comes from slow-moving thunderstorms dumping heavy rain in a short time. Lincoln County is largely rural desert, and desert terrain floods fast: dry washes, normally empty creek beds, and low-water crossings can fill with fast-moving water in minutes, even if the rain is falling miles away upstream.
What residents and travelers might notice
Expect rapid rises in washes and small drainages, water over rural roadways and low-water crossings, and possible debris flows near recently burned slopes. U.S. Route 93 and State Route 318, which pass through Lincoln County, could see water or mud on the pavement in spots. Anyone recreating in slot canyons or desert washes should leave immediately.
Who is affected: residents of Lincoln County communities — including Panaca, Pioche, Caliente, and Alamo — as well as drivers passing through the region during the warning window.
Sensible precautions for the next few hours:
— Never drive or walk through floodwater. Six inches of moving water can knock a person down, and a foot can carry a vehicle away. If a road is covered, turn around.
— Stay out of dry washes and canyon bottoms, even under blue skies overhead — runoff travels far downstream.
— Keep a phone charged and weather alerts enabled, and be ready to move to higher ground if water begins rising near your home.
The warning is currently set to expire at 3:00 PM PDT, though it could be extended if heavy rain continues. This alert is based on data issued by the National Weather Service office in Las Vegas, Nevada.
Frequently Asked Questions
What should I do right now?
Move to higher ground if you're in a wash, canyon, or low-lying area, and stay off flooded roads. Keep weather alerts turned on until the warning expires at 3:00 PM PDT.
How long will this last?
The warning runs until 3:00 PM PDT on September 28, but NWS Las Vegas may extend it if heavy rain persists. Flood water in washes can remain dangerous even after the rain stops.
Is it safe to drive through Lincoln County right now?
Travel with caution and be prepared to stop or reroute — never cross water covering the roadway. Low-water crossings on rural routes can flood with little warning.
Can it flood where I am even if it isn't raining overhead?
Yes. Desert flash floods often come from storms miles upstream, sending water rushing down dry washes and canyons under clear local skies.
