...FLASH FLOOD WATCH IN EFFECT THROUGH THIS EVENING...

The National Weather Service in Las Vegas has issued a

* Flash Flood Watch for portions of south central Nevada and 
  southern Nevada, including the following areas, in south central 
  Nevada, Lincoln County. In southern Nevada, Sheep Range.

* Through this evening.

* Thunderstorms capable of heavy rainfall resulting in flash 
  flooding, especially in high terrain areas. Areas that have 
  already received several rounds of heavy rainfall over the last 
  several days will be highly vulnerable to additional impacts 
  should more storms impact those areas.

* Rapid onset of flash flooding is possible. This could impact parts 
  of Highway 93 across Lincoln County as well as smaller county 
  roads that lead up to high terrain locations. Washes could very 
  quickly become flooded due to several days of heavy rainfall in 
  these areas.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

Turn around, don't drown when encountering flooded roads. Most flood 
deaths occur in vehicles.

Washes could very quickly become flooded and become life-threatening 
for those recreating. Avoid recreation in washes or low lying areas 
such as slot canyons as these can quickly become flooded.
