...Remnants of Hurricane Ida to Bring Heavy Rainfall to the 
Region Tuesday Afternoon through Wednesday...

.The remnants of Hurricane Ida, now located in west central
Mississippi, will turn northeast today into Tuesday and move 
toward southwest Virginia and southern West Virginia by late
Tuesday into early Wednesday. This will bring widespread heavy
rainfall to the region, first in the form of spiral bands of
locally heavy rainfall and scattered thunderstorms Tuesday
afternoon and evening transitioning to a more stead moderate to
occasionally heavy rainfall Tuesday night into Wednesday. The
heavy rainfall associated with the remnants of Hurricane Ida will
then move to the northeast of the area by Wednesday evening with
dry weather conditions returning to most of the region by
Thursday. The heaviest rainfall is expected to occur along and
west of a line from Hot Springs to Covington to Blacksburg to
Hillsville with lesser rainfall amounts east and southeast of this
line. Minor adjustments in the eventual track of the remnants of
Hurricane Ida could bring heavier rainfall to areas further east
and south resulting in additional counties being added to the
Flash Flood Watch with later forecast updates.

...FLASH FLOOD WATCH IN EFFECT FROM TUESDAY AFTERNOON THROUGH
WEDNESDAY EVENING...

The National Weather Service in Blacksburg has issued a

* Flash Flood Watch for portions of southwest Virginia and 
  southeast West Virginia, including the following areas, in 
  southwest Virginia, Bland, Carroll, Giles, Grayson, Pulaski, 
  Smyth, Tazewell, and Wythe. In southeast West Virginia, 
  Eastern Greenbrier, Mercer, Monroe, Summers, and Western 
  Greenbrier. 

* From Tuesday afternoon through Wednesday evening.

* Heavy rainfall is expected as the remnants of Hurricane Ida move
  through the region Tuesday afternoon through Wednesday morning.
  Widespread rainfall amounts of 2 to 4 inches are expected with
  locally heavier amounts of 3-5 inches possible where any spiral
  rain bands set up and persist over a particular area for any
  period of time. Localized thunderstorms could also result in
  excessive rainfall in some locations.

* Widespread minor flooding is expected which will impact low-
  lying, poor drainage, and typically flood prone areas. Small
  creeks and streams will likely rise out of their banks and flood
  adjacent areas. Flash flooding will be possible in areas where 
  heavier rainfall occurs. Landslides and mudslides will also be 
  possible in areas of steep mountainous terrain. Some roads and 
  highways could become closed as a result of mudslides and/or 
  flooding/flash flooding.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

A Flash Flood Watch means that conditions may develop that lead
to flash flooding. Flash flooding is a VERY DANGEROUS SITUATION. 
Check preparedness requirements and be ready for quick action if 
a Flash Flood Warning is issued or flash flooding is observed. 
Seek higher ground immediately. Do not drive your vehicle into 
areas where water covers the road. Remember...TURN AROUND...DON'T 
DROWN!

You should monitor later forecasts and be prepared to take action
should Flash Flood Warnings be issued.

...FLASH FLOOD WATCH REMAINS IN EFFECT THROUGH WEDNESDAY EVENING...

The Flash Flood Watch continues for

* Portions of North Carolina, Virginia and southeast West Virginia, 
  including the following areas, in North Carolina, Alleghany NC, 
  Ashe, Stokes, Surry, Watauga, Wilkes and Yadkin. In Virginia, 
  Alleghany VA, Amherst, Bath, Bedford, Bland, Botetourt, Carroll, 
  Craig, Floyd, Franklin, Giles, Grayson, Montgomery, Patrick, 
  Pulaski, Roanoke, Rockbridge, Smyth, Tazewell and Wythe. In 
  southeast West Virginia, Eastern Greenbrier, Mercer, Monroe, 
  Summers and Western Greenbrier.

* Through Wednesday evening.

* Widespread heavy rain is expected first with the spiral bands of
  showers and scattered thunderstorms this evening, then transition 
  to a steadier moderate to occasionally heavy rainfall tonight into 
  Wednesday. Rainfall amounts of 1 to 3 inches will be common, with 
  locally heavier amounts of 2 to 5 inches possible where any rain 
  bands set up and persist over a particular area. Localized 
  thunderstorms could also result in high rainfall rates.

* Widespread minor flooding is expected which will impact low-lying, 
  poor drainage, and typically flood prone areas. Small creeks and 
  streams will likely rise out of their banks and flood adjacent 
  areas. Landslides and mudslides will also be possible in 
  areas of steeper terrain closer to the Blue Ridge. Some roads and 
  highways could become impassable as a result of mudslides and/or 
  stream and creek flooding.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

A Flash Flood Watch means that conditions may develop that lead
to flash flooding. Flash flooding is a VERY DANGEROUS SITUATION. 
Check preparedness requirements and be ready for quick action if 
a Flash Flood Warning is issued or flash flooding is observed. 
Seek higher ground immediately. Do not drive your vehicle into 
areas where water covers the road. Remember...TURN AROUND...DON'T 
DROWN!

You should monitor later forecasts and be prepared to take action
should Flash Flood Warnings be issued.
