...FLOOD WATCH IN EFFECT FROM MONDAY AFTERNOON THROUGH THURSDAY 
MORNING...

* WHAT...Flooding caused by rain and snowmelt is possible.

* WHERE...Clearwater and Idaho County, Idaho. 

* WHEN...From Monday afternoon through Thursday morning.

* IMPACTS...Creeks and streams may rise out of their banks. Flooding 
  may occur in poor drainage and urban areas. Storm drains and 
  ditches may become clogged with debris. People, structures, and 
  roads located below steep slopes, in canyons, and near the mouths 
  of canyons may be at risk from landslides.

* ADDITIONAL DETAILS...
  - A prolonged atmospheric river is expected to bring periods of
    heavy rain to Idaho and Clearwater Counties, Monday night
    through Thursday. Rising snow levels will lead to a rain on
    snow event for elevations below 7,000 feet Monday night into
    Tuesday morning. The precipitation rates will briefly
    decrease Tuesday afternoon, before a second surge of moisture
    arrives Tuesday night into Thursday morning. By Thursday,
    significant precipitation totals are forecast, with 2 to 4
    inches in the valleys and 4 to 8 inches in the mountains,
    with locally higher totals over mountain crests. Landslides
    in areas of steep terrain and minor flooding in urban and
    poor drainage areas is possible.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

You should monitor later forecasts and be alert for possible Flood 
Warnings. Those living in areas prone to flooding should be prepared 
to take action should flooding develop.
