Flash Flood Watch
Issued by the National Weather Service at 8:52 am EDT on September 5, 2008
... Flash Flood Watch remains in effect from Saturday morning
through Saturday afternoon...
The Flash Flood Watch continues for
* portions of Maryland... the District of Columbia and Virginia...
including the following areas... in Maryland... Anne Arundel...
Calvert... Carroll... Charles... Frederick MD... Harford...
Howard... Montgomery... northern Baltimore... Prince Georges...
southern Baltimore and St. Marys. The District of Columbia. In
Virginia... Arlington/Falls Church/Alexandria... Culpeper...
Fairfax... Fauquier... King George... Loudoun... Orange... Prince
William/Manassas/Manassas Park... Spotsylvania and Stafford.
* From Saturday morning through Saturday afternoon
* heavy rain associated with Tropical Storm Hanna will move
northwest across the region 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 higher
amounts up to 10 inches. 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.

Sustained winds of 30 to 40 mph with gusts up to 50 mph are
possible beginning early Saturday morning and lasting into the
late afternoon. The strongest winds will occur east of the
Interstate 95 corridor... with southern Maryland having the highest
likelihood of strongest winds. Winds of this magnitude may cause

Tropical storms are capable of producing very heavy rainfall in a
short amount of time. While it has been dry during the past month
it will be possible for smaller creeks and streams in the region
to rise above bankfull very quickly... creating a flash flood and a
potentially life threatening situation. If you see flash flooding
occurring... report this to law enforcement immediately. Motorists
should be alert for flooding on roadways on Saturday.
