Flash Flood Watch
Issued: 12:35 PM EDT Aug. 18, 2017 – National Weather Service

... Flash Flood Watch in effect through late tonight...

The National Weather Service in Sterling Virginia has issued a

* Flash Flood Watch for portions of Maryland, the District of
Columbia, and Virginia, including the following areas, in
Maryland, Anne Arundel, Calvert, Carroll, central and
southeast Howard, central and southeast Montgomery, Charles,
Frederick MD, northern Baltimore, northwest Harford, northwest
Howard, northwest Montgomery, Prince Georges, southeast
Harford, southern Baltimore, and St. Marys. The District of
Columbia. In Virginia, Arlington/Falls Church/Alexandria,
Culpeper, eastern Loudoun, Fairfax, King George, Madison,
northern Fauquier, Orange, Prince William/Manassas/Manassas
Park, Rappahannock, southern Fauquier, Spotsylvania, Stafford,
and western Loudoun.

* Through late tonight

* thunderstorms with heavy rainfall are expected across the region
this afternoon and evening. The potential for training
thunderstorms exists, which could result in several inches of
rain in one to two hours. Soils are already very moist, meaning
most of this rain would rapidly run off.

* Runoff from excessive rainfall may cause rapid rises of water
in low-lying and poor drainage areas as well as streams and
creeks, resulting in flash flooding. Urban areas will be most
susceptible.

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.

Heat Advisory
Issued: 11:15 AM EDT Aug. 18, 2017 – National Weather Service

... Heat advisory remains in effect until 8 PM EDT this evening...

* heat index values... around 105 degrees due to temperatures in
the lower 90s and dewpoints in the mid to upper 70s.

* Impacts... the heat and humidity may cause heat stress during
outdoor exertion or extended exposure.

Precautionary/preparedness actions...

A heat advisory means that a period of high temperatures is
expected. The combination of high temperatures and high humidity
will create a situation in which heat illnesses are possible.

Take extra precautions if you work or spend time outside. When
possible, reschedule strenuous activities to early morning or
evening. Know the signs and symptoms of heat exhaustion and heat
stroke. Wear light weight and loose fitting clothing when
possible and drink plenty of water.

To reduce risk during outdoor work, the occupational safety and
health administration recommends scheduling frequent rest breaks
in shaded or air conditioned environments. Anyone overcome by
heat should be moved to a cool and shaded location. Heat stroke
is an emergency - call 911.
