Areal Flood Watch
Issued by the National Weather Service at 3:38 PM EST on March 12, 2010


... Flood Watch remains in effect from 7 PM EST this evening
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.

* From 7 PM EST this evening 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 up to 5 inches
possible.

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.
