LAS VEGAS (KSNV MyNews3.com) -- A flash flood advisory has been amended for the Lovell and Trout canyon areas near Mt. Charleston.
Storms are also expected later today in the Las Vegas Valley.
Flooding has been reported on Tecopa Road near the California-Nevada border several dozen miles south of Mt. Charleston.
The National Weather Service issued a warning at 12:14 p.m. Saturday and said it will last until 3:15 p.m. for an area about seven miles south of Mt. Charleston in the burn area from last year's Carpenter One fire.
The NWS said radar indicated rainfall that was producing flash flooding moving west at 5 miles an hour.
Earlier this afternoon the NWS revised the warning to call it an advisory and said it would extend until 4:30 p.m. Saturday.
At 1:37 p.m. a thunderstorm was producing heavy rain on the west side of last year's Carpenter 1 burn scar. The rain will lead to increased runoff and minor flooding on downstream washes and streams, according to the NWS.
The affected areas include Mt. Charleston and the following campgrounds: Kyle Canyon, Fletcher View, Hilltop, Mahogany Grove and Mary Jane Falls.
UPDATES: A power outage was reported shortly after 1:30 p.m. on Sandy Valley Road (Nevada 161) halfway between Kean and Sandy Valley. Just over 100 customers were affected, according to the NV Energy outage website. Power was restored before 3 p.m.
As of 2:30 p.m., the NWS was reporting that 3 to 4 inches of water was running over Tecopa Road near the California-Nevada border as a result of runoff from the storms near Mt. Charleston. Hail was reported earlier at the ski area of Mt. Charleston, and hail was reported between Barstow and Baker in California.
The hazardous weather outlook will continue this evening and Sunday in southern Nevada, according to the NWS.
Isolated to scattered thunderstorms producing erratic and gusty winds and brief periods of heavy rain are expected this afternoon and tonight.
Some dry lightning is expected, primarily in Lincoln County. A red flag warning remains in effect with high winds possibly blowing dust across the lower deserts.
Monsoon moisture will remain possible across the region into next week. The main threats will be erratic gusty winds with brief periods of heavy rainfall and dangerous lightning possible for most of southern Nevada, northwest Arizona and the high desert of California.
