...FLOOD WATCH REMAINS IN EFFECT THROUGH 4 AM PST TUESDAY MORNING...

The Flood Watch continues for

* A portion of northern California, including the following area, 
  Western Siskiyou County.

* Through late Monday night

* Periods of moderate to heavy rainfall are expected through 
  Tuesday morning resulting in storm total rainfall amounts of 2 to 
  as much as 6 inches across much of western Siskiyou County near, 
  over portions of, and
  west of the Marble Mountains. Recent significant snowfall in the  
  mountains below 6,000 foot elevations is expected to receive rain 
  on it as snow levels rise into the
  5,000 to 6,000 foot range, increasing run-off across the area. 
  Areas below 5,000 foot elevations are expected to see significant 
  melting of the snowpack.

* Small streams and creeks could reach bankful or even flood during 
  this time period. Areas with poor drainage could see significant 
  ponding of water in low lying areas. No main stem river flooding 
  is expected.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

Do not enter or cross flowing water or water of unknown depth.

Stay away or be swept away. River banks and culverts can become 
unstable and unsafe.

A Flood Watch means there is a potential for flooding based on 
current forecasts. 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.

...FLOOD WATCH REMAINS IN EFFECT THROUGH LATE MONDAY NIGHT...

The Flood Watch continues for

* A portion of southwest Oregon, including the following areas, 
  Curry County Coast, Eastern Curry County and Josephine County and 
  South Central Oregon Coast.

* Through late Monday night

* Periods of moderate to heavy rainfall are expected through Tuesday 
  morning resulting in additional rainfall amounts of 2 to 6 inches 
  across Curry County, 2 to 4 inches across Coos County, and 2 to 5 
  inches across Josephine County. Recent significant snowfall in the 
  mountains is also expected to melt substantially as snow levels 
  rise into the 5,000 to 6,000 foot range, increasing run-off across 
  the area.

* Small streams and creeks could reach bankful or even flood during 
  this time period and urban areas could see significant ponding 
  water in low lying areas and areas with poor drainage. Currently 
  there is concern that the South Fork of the Coquille River at 
  Myrtle Point could peak at Minor Flood Stage and that the South 
  Fork of the Coquille at Powers and the Coquille River at Coquille 
  could peak between Action Stage and Flood Stage.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

Do not enter or cross flowing water or water of unknown depth.

Stay away or be swept away. River banks and culverts can become 
unstable and unsafe.

A Flood Watch means there is a potential for flooding based on
