Detailed History and Climate

Areal Flood Watch

Issued by the National Weather Service at 2:27 PM EST on March 11, 2010

... Flood Watch in effect from Friday evening through late
Saturday night...

The National Weather Service in State College has expanded the

* Flood Watch to include a portion of central Pennsylvania...
including the following areas... Adams... Bedford... Blair...
Cumberland... Dauphin... Franklin... Fulton... Huntingdon...
Juniata... Lancaster... Lebanon... Mifflin... Perry... Schuylkill
and York.

* From Friday evening through late Saturday night.

* A storm system is expected to form along the Carolina coast
Friday... then move up along the eastern Seaboard Saturday. The
storm will spread rain into the area... beginning during the day
Friday and lasting through most of the weekend. The heaviest
rains are expected to fall from around midnight Friday night
through the day Saturday. Widespread amounts of 2 inches or
more are expected before the storm winds down later in the
weekend. The combination of the heavy rain and snow melt will
create the potential for flooding on regional rivers and streams.

* With the amount of rain expected... and some areas still having
considerable amounts of high water content snow on the
ground... this has the potential to be a very dangerous flooding
situation developing over the next couple of days. Persons near
flood prone areas should keep a close watch on later
forecasts... statements and changing weather conditions.

Precautionary/preparedness actions...

A Flood Watch means there is a potential for flooding on small
streams... creeks... poor drainage... urban and low-lying areas
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.
