Flash Flood Watch, Coastal Flood Advisory

Expires 9:00 AM EDT on July 23, 2018
Statement as of 10:09 PM EDT on July 22, 2018

... Flash Flood Watch now in effect until 5 am EDT Monday...

The Flash Flood Watch is now in effect 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, eastern Loudoun,
Fairfax, King George, Prince William/Manassas/Manassas Park,
Spotsylvania, and Stafford.

* Until 5 am EDT Monday

* periods of showers and thunderstorms may continue overnight and
into Monday morning. There is potential for repetitive rounds of
precipitation. Combined with saturated ground and high stream
levels from recent rainfall, this precipitation could lead to
flash flooding.

* Urban areas, locations along small streams and creeks, and
poor drainage areas are most vulnerable to 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.

You should monitor later forecasts and be prepared to take action
should flash flood warnings be issued.




651 PM EDT sun Jul 22 2018

... Coastal flood advisory remains in effect from 2 am to 9 am EDT
Monday...

* locations... shoreline in southern Baltimore County and the
city of Baltimore.

* Tidal departure... one to two feet above normal.

* Timing... around the time of high tide early Monday morning.
High tide at Bowley Bar is at 5:48 am and at Baltimore at 4:32
am Monday.

* Impacts... flooding is expected at the end of Thames street in
Baltimore. Water also is expected to cover the promenade at The
Dragon boat dock in the Inner Harbor. Minor shoreline
inundation up to one foot above ground is possible elsewhere.

Precautionary/preparedness actions...

A coastal flood advisory indicates that onshore winds and tides
will combine to generate flooding of low areas along the shore.



Forecast tides are referenced to mean lower low water
(mllw) and mean higher high water (mhhw) unless
otherwise noted. Time of high total tide is
approximate to nearest hour. Total tide combines the
normal tide and departure from normal. Flood impact
is based on the total tide and waves where applicable.
