...FLASH FLOOD WATCH IN EFFECT THROUGH SATURDAY MORNING...

The National Weather Service in Peachtree City has issued a

* Flash Flood Watch for North and Central Georgia.

* Through Saturday morning

* Additional rounds of very heavy rainfall are likely as a trough
  of low pressure to the west feeds very high amounts of moisture
  into the area. Total rainfall amounts through Friday night could
  range from 2 to 4 inches with isolated amounts up to 8 inches.
  Much of this heavy rain could fall in a short amount of time.
  With the heavy rain that has already fallen in the last 2 days,
  it will only take a relatively small amount of heavy rain to 
  cause significant flash flooding.

* Creeks and rivers will rise out of their banks closing roads or
  impacting homes, businesses and farms. Roads may become closed
  for extended periods of time. High water will not recede until
  well after the rain has ended. 

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.

...FLASH FLOOD WATCH REMAINS IN EFFECT THROUGH SATURDAY MORNING...

The Flash Flood Watch continues for

* North and Central Georgia.

* Through Saturday morning

* Additional rounds of very heavy rainfall are likely as a trough
  of low pressure to the west feeds very high amounts of moisture
  into the area. Widespread rainfall amounts of one to two inches
  are likely. Locally higher amounts of 3 inches or more are 
  possible where storms repeatedly move. Much of this heavy rain 
  could fall in a short amount of time. With the heavy rain that 
  has already fallen in the last 2 days, it will only take a 
  relatively small amount of rainfall to cause significant flash 
  flooding.

...FLASH FLOOD WATCH IS CANCELLED...

The Flash Flood Watch for North and Central Georgia has been
cancelled. Although the soils across north and central Georgia remain
at or near saturation, the chances for widespread heavy rain have
temporarily diminished. Local areas of heavy rain will still be
possible today through tonight, however widespread flood issues are 
not anticipated. 

With the forecast path of Subtropical Storm Alberto likely to begin 
impacting the region later in the weekend through the beginning of 
next week, the potential for more widespread heavy rain may be on 
the increase once again by Sunday through the middle of next week.
