Flash Flood Watch
Issued by the National Weather Service at 8:52 am EDT on September 5, 2008
... Flash Flood Watch in effect from Saturday morning through
Saturday afternoon...
The National Weather Service in Sterling Virginia has expanded
the
* Flash Flood Watch to include portions of north central
Maryland... Virginia and northeast West Virginia... including
the following areas... in north central Maryland... Washington.
In Virginia... Albemarle... Augusta... Clarke... Frederick VA...
Greene... Madison... Nelson... Page... Rappahannock... Rockingham...
Shenandoah and Warren. In northeast West Virginia... Berkeley
and Jefferson.
* From Saturday morning through Saturday afternoon
* heavy rain associated with Tropical Storm Hanna will move
northwest across the region early Friday evening into Saturday.
It appears at this time that the heaviest rains would fall late
Friday night into late Saturday afternoon. This is largely
dependent on the exact track of Hanna. However... along the path
of this storm totals of 4 to 7 inches with localized amounts up
to 10 inches are expected. Latest flash flood guidance
indicates that amounts of 3 to 4 inches in 3 hours or less will
cause small streams and creeks to flow out of their banks.
* If heavy rain develops... expect small streams to overflow and
low lying roads to flood. Do not ever drive into flood waters.
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.
