Areal Flood Watch
Issued by the National Weather Service at 10:44 PM EST on March 12, 2010
... Flood Watch remains in effect through Sunday morning...
The Flood Watch continues 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... coastal ocean...
Cumberland... eastern Monmouth... Gloucester... Hunterdon...
Mercer... Middlesex... Morris... northwestern Burlington...
ocean... Salem... Somerset... southeastern Burlington... Sussex...
Warren and western Monmouth. In Pennsylvania... Berks... Bucks...
Carbon... Chester... Delaware... Lehigh... Monroe... Montgomery...
Northampton and Philadelphia.
* Through Sunday morning
* periods of rain will occur across the area into Sunday
morning. The heaviest rain is anticipated to occur starting
late tonight and especially during Saturday.
* Widespread total rainfall amounts of 2 to 4 inches are
anticipated with this storm... with locally around 5 inches
possible.
The first area of heavy rain will be affecting Delmarva,
southeastern New Jersey over the next few hours. This area is
expected to weaken as it moves farther away from the surface low
later tonight. Then the convective heavy rain over the Carolinas
should then move into the region during the day on Saturday into
Saturday evening.
Given this amount of rain... the potential exists for areas of
dangerous flooding to develop over the next couple of days. Small
streams and possibly main Stem rivers will reach flood stage.
Smaller streams will respond first to the rainfall followed by the
larger rivers. Flooding could begin toward daybreak Saturday along
fast responding creeks... while the larger... slower responding
rivers could see flooding persist into early next week. In
addition... these rainfall amounts will cause areas of flooding on
roadways and poor drainage.
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.
