... Flash Flood Watch in effect until 6 PM EDT this evening...
The National Weather Service in Blacksburg has issued a
* Flash Flood Watch for portions of central Virginia... south
central Virginia... southwest Virginia and west central
Virginia... including the following areas... in central
Virginia... Amherst... Appomattox... Buckingham and Campbell. In
south central Virginia... Bedford. In southwest Virginia...
Craig. In west central Virginia... Alleghany VA... Bath...
Botetourt... Franklin... Roanoke and Rockbridge.
* Until 6 PM EDT this evening
* locally heavy rain fell over parts of the watch area last
night... in some cases upwards of 3 inches. An additional 1 to 3
inches of rain is likely today. If rainfall exceeds 2 inches in
an hour... flash flooding will become likely.
* Streams in parts of Bath... Rockbridge... and Alleghany counties
are already running high due to last nights rainfall. Additional
rainfall today will cause these streams to go even higher.
Be aware of sudden bursts of very heavy rain... and especially if
they are associated with thunderstorms. Rain rates associated with
storms today may approach 4 inches in an hour. With this sort of
rate... just 15 minutes would cause ditches to overflow putting
debris on high ways. 30 minutes of this sort of rain would bring
streams to bankfull. And 45 minutes to an hour of these sort of
rain rates would result in flash flooding.
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.
