...FLASH FLOOD WATCH HAS EXPIRED...

The Flash Flood Watch for portions of east central California and 
western Nevada has expired.

Storms have weakened. Therefore, the threat of flash flooding has 
dropped considerably. Nocturnal thunderstorms may still pose a flash 
flooding threat, especially near recent burn scars and steep 
terrain. However, these threats will be localized and not widespread 
if they do occur. Please continue to heed remaining road closures.
