Areal Flood Watch
Issued by the National Weather Service at 3:44 PM EST on March 11, 2010
... Flood Watch in effect from Friday evening through Sunday
morning...
The National Weather Service in Mount Holly has issued a
* Flood Watch for portions of Delaware... northeast Maryland...
New Jersey and Pennsylvania... including the following areas...
in Delaware... Delaware beaches... inland Sussex... Kent and New
Castle. In northeast Maryland... Caroline... Cecil... Kent MD...
Queen Annes and Talbot. In New Jersey... Atlantic... Atlantic
coastal Cape May... Camden... Cape May... coastal Atlantic...

Burlington... ocean... Salem... Somerset... southeastern
Burlington... Sussex... Warren and western Monmouth. In
Pennsylvania... Berks... Bucks... Carbon... Chester... Delaware...
Lehigh... Monroe... Montgomery... Northampton and Philadelphia.
* From Friday evening through Sunday morning
A complex storm system will be affecting the region through
Sunday. An area of low pressure over the central portion of the
nation will move eastward through Saturday. A second low pressure
system is then expected to form near the North Carolina/Virginia
border and move generally northward Saturday into Sunday.
The combination of all of these low pressure systems will bring
rain to the area beginning on Friday. The rain will become
steadier and heavier Friday night into Saturday as the second low
approaches the region.
Widespread rainfall amounts of 2 to 4 inches are anticipated with
this storm. Local amounts up to 5 inches are possible, especially
in those locations that receive the heaviest rain.
Given this amount of rain, small streams and possibly mainstem
rivers will reach flood stage. Smaller streams will respond first
to the rainfall followed by the larger rivers. Flooding could
begin as soon as late Friday night along fast responding creeks,
while the larger, slower responding rivers, could see flooding
persist into early next week. These rainfall amounts also have the
potential to cause flooding of roadways and poor drainage areas.
If you are traveling, please allow extra time to reach your
destination. In addition to any flooding, heavy rain can cause
reduced visibilities. Please stay tuned to NOAA Weather Radio or
your favorite media outlet for further updates and any possible
warnings. People who live near rivers or streams that are prone to
flooding should be on heightened alert and should be prepared to
take action if flooding develops.
Precautionary/preparedness actions...
A Flood Watch means there is a potential for flooding based on
current forecasts.
You should monitor later forecasts and be alert for possible
flood warnings. Those living in areas prone to flooding should be
prepared to take action should flooding develop.
