Flood warnings in the area have prompted Clark County Manager Virginia Valentine to issue a declaration of emergency to deal with the threat of flooding in the area.

An emergency operations center has been set up at the Clark County Government Center in downtown Las Vegas. The declaration means that there is a state of emergency because of weather conditions, officials said.

“With a declaration in place, we can call upon other public entities for assistance, including the state of Nevada and the federal government to get resources as quickly as possible,” Valentine said in a prepared statement.

Mesquite

Earlier Tuesday afternoon, the National Weather Service issued a civil emergency message at the request of the Mesquite Police Department because of flooding in that city.

The message said voluntary evacuations due to flooding east of Sage Way are now occurring between East Mesquite Boulevard and East Old Mill Road in Mesquite. An evacuation center has been set up at Virgin Valley High School and sandbags are available at Hunter Park. Mesquite residents can call 702-346-5295, ext. 5101 for more information.

The power outage in Kyle Canyon – which is affecting around 500 customers -- is expected to last at least 72 more hours, according to NV Energy spokesman Mark Severts.

“This is the worst storm in the memory of our crews that they’ve ever had to battle,” Severts said.

Severts said that the Mount Charleston area has been so dangerous that NV Evergy crews are being pulled for the rest of the day and expect to return to work on the area at daylight.

He said heavy snowfall has been building up on trees and limbs, causing some trees to fall into powerlines and cabins.

“Those branches could break at any moment,” Severts said. “That needs to be their number one concern.”

Snow is also building up on the powerlines itself and causing them to fall, he said. There was also an active avalanche in the early afternoon.

So far there has been 3 feet of snow accumulated in the area and another 10 inches is expect overnight, Severts said.

NV Energy is discouraging people from going to play in the snow on Mount Charleston, and asking them to avoid any NV Energy crews doing work in the area.

Stacey Wellling, Clark County public information officer, said the county's Public Works may be gearing up to do 24-hour snow removal at Mount Charleston, which got 2 feet of snow between 6 p.m. Monday and 3:30 a.m. today. She said that there are also a lot of power lines down at Echo Canyon this morning. Public Works reports they are plowing Echo Subdivison now. They can't access a back road into the subdivision due to the down power lines, but they can access via other roads, she said.

Road closings today included Arroya Road going into the town of Blue Diamond, Bonnie Springs Road and Elbow Canyon Road, outslde of Bunkerville, which is a dirt road that was washed out, she said. No roads are closed in Moapa Valley, but Public Works is monitoring Cooper Crossing in case of flooding on the Muddy River, she said.

State Route 159 is closed at mile marker 13, said National Highway Patrol Trooper Chelita Rojas. Rojas said she isn’t sure when the route will reopen — that will depend on the weather and flooding in the area, she said.

Clark County Public Works is monitoring the Flamingo Wash area behind Imperial Palace, she said.

Metro Police confirmed road closures on State Route 157, Kyle Canyon Road; State Route 156, Lee Canyon Road, above the 12-mile markers on each. State Route 158, the road that connects Kyle Canyon Road and State Route 156, is completely closed to traffic.

Police said that residents driving four-wheel drive vehicles or tire chains will be allowed past emergency check points.

A very moist Pacific storm is expected to continue bringing wet weather and snow to the region through Wednesday, according to the National Weather Service.

Widespread valley rain and more snow can be expected, with locally heavy rain potentially causing flooding, the weather service said.

Heavy snow will fall in the Spring Mountains and Sheep Range in southern Nevada through Wednesday evening, but will leave to the east late Wednesday night, leaving dry conditions Thursday and Friday, forecasters said.

Flash flood watch

A flash flood watch continues through Wednesday afternoon for portions of northwest Arizona, California and southern Nevada, including the Las Vegas Valley and Lake Mead National Recreation Area, the weather service said.

Rain is expected to become more scattered during the day today. However, more rain, locally heavy at times, is expected tonight and Wednesday, forecasters said.

The rain will cause ponding of water in low lying areas as well as rapidly flowing water in normally dry washes, they said. Flows of water and mud or debris might occur over area roads, they said. Travelers, campers and residents should be aware of the potential for flash flooding, they said.

Winter storm warning in mountains

The weather service has issued a winter storm warning for heavy snow and strong winds for areas above 7,000 feet in the the Sheep Range, the Spring Mountains, Red Rock Canyon and the town of Mount Charleston through 10 p.m. Wednesday.

Snowfall will be heavy at times today before tapering off some tonight, then increasing again late tonight and Wednesday evening, forecasters said.

Total accumulations of up to 4 feet of snow are possible at the 7,500-feet level, with 6 feet or more at the highest elevations through Wednesday evening, they said.

The latest 24-hour snow totals this morning include the Nevada Division of Forestry in Kyle Canyon, with 16 inches and the Las Vegas Ski and Snowboard Resort with 26 inches, forecasters said.

Winds will be from the west at 20 to 30 mph, with gusting.

Travel will be difficult or impossible at times on roads above 7,000 feet, including State Roads 156, 157 and 158 in Kyle and Lee Canyons, forecasters said.

Flood warning continues

A flood warning has been extended through Thursday evening for the Virgin River and Beaver Dam Wash in northeastern Clark and north central Mohave counties, forecasters said.

At 12:25 p.m., flooding was occurring on the Beaver Dam Wash at Beaver Dam, Ariz., and mandatory evacuations were in effect, the weather service said.

Stream flows similar to , if not higher than 2005 are occurring on the Virgin River from Littlefield to Lake Mead, forecasters said. One to 2 feet of water in extreme southeast Mesquite is occurring near East Mesquite Boulevard and Cottonwood, forecasters said. Flood mitigation activities are occurring around Mesquite, they said.

The Virgin River and Beaver Dam Wash will continue to flood through Thursday evening, they said.

A flood warning means that flooding is imminent or has been reported, forecasters said. They urged motors not to dirve vehicles into areas where the water covers the roadway.

Flood advisory

The weather service has extended the flood advisory until 5 p.m. for west central Clark County in southern Nevada. Locations affected include Red Rock Canyon, Spring Mountain Ranch, Blue Diamond and Rocky Gap Campground.

At 1:44 p.m., radar continued to indicate light to moderate rain in and around the Red Rock Canyon area. Highway 159 and the Red Rock Scenic Loop Road remain closed, forecasters said. Flooding will continue to be a threat through 5 p.m., they said.

Christmas weather outlook

Forecasters said a weak ridge of high pressure will move over the region on Thursday, bringing drier conditions. However, that will be short lived.

Another weaker storm will move across the region over the Christmas weekend, bringing a chance of rain and snow once again north of Las Vegas. Dry conditions are expected by next Monday as that system shifts to the east.

Record rainfall recorded Monday

McCarran Internation Airport's daily rain total Monday was .4 of an inch, which broke the old Dec. 20 daily record of .25 of an inch set back in 1959.

  1. Waiting to see an Ark on the STRIP!

  2. @ revtomperl:

    Don't give Steve Wynn any ideas, he might open a Noah's Ark Casino!

    :)

  3. fill lake mead up!!!!

  4. People can be electrocuted standing in puddles or trip on unseen hazards.

  5. I remember one winter, it may have been my second winter in Vegas, it rained and rained and rained for about 12 days. Plants in the desert were blooming that hadn't done so in 100 years!! Water was coming into the garage floor and we couldn't figure out where it was coming from (we actually did remove all the decorative rock next to the foundation). I remember constantly checking the upstairs rooms looking for leaks!! But as soon as the rain stopped, that damn desert ground was still as hard as a rock!! Hardly even damp!

  6. Now rain is good since we don't get much of it but hate to tell some, rain in this valley does not help Lake Mead.

    Now, all the rain in So. Cal. is helping because they cut their water orders and take less when they get to much rain. That does help the lake because they are not drawing as much from it.

    A bit of wet is good for the valley though. Keeps some of you from over watering your yards. ;-)

  7. Gee this is all government. I thought NPRI and the liberloontoonians don't like government. Maybe they can form a private sector bucket brigade. Sherm, Vin..get out there with your sham-wows and deal with the floods.

  8. Hey, surface drainage does go into lake mead so all of you can enjoy drinking the dirt from the leaky seals on your cars!

    No, it's not sad. I still have people I care about living in Las Vegas and because I liked living in Vegas, like to keep up on what's happening back there.

    And yes, I am kinda bored right now. I start a new job on Jan. 3 so I have easy time on my hands and a very limited budget so can't go hang out and shop!

    BTW - there are quite a few people who don't live in Vegas commenting on this site all the time!! Haven't you realized that yet?? And what about YOUR life that you even noticed that I comment here?
