* the primary impacts will be localized ponding of water on low 
  lying roadways with poor drainage...rapid rises on streams and 
  creeks with some likely exceeding bankfull...some river 
  flooding...and potential rock and mud slides. recent burn 
  scars will also be susceptible to debris flows during periods 
  of intense rainfall. 

precautionary/preparedness actions...

a flash flood watch means that conditions may develop that lead
to flash flooding. flash flooding is a very dangerous situation.

you should monitor later forecasts and be prepared to take action
should flash flood warnings be issued.
