335 PM EDT Wed May 16 2018

...FLOOD WATCH IN EFFECT FROM THURSDAY EVENING THROUGH LATE
FRIDAY NIGHT...

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, Coastal Ocean,
  Cumberland, Eastern Monmouth, Gloucester, Hunterdon, Mercer,
  Middlesex, Northwestern Burlington, Ocean, Salem, Somerset,
  Southeastern Burlington, Warren, and Western Monmouth. In
  Pennsylvania, Berks, Delaware, Eastern Chester, Eastern
  Montgomery, Lehigh, Lower Bucks, Northampton, Philadelphia,
  Upper Bucks, Western Chester, and Western Montgomery.

* From Thursday evening through late Friday night

* Periods of light to moderate rain will continue this afternoon
  through tomorrow. A brief break in the rain is expected early
  tomorrow evening before it once again intensifies and becomes more
  widespread tomorrow night. Periods of moderate to heavy rain are
  then expected to persist into at least Friday, possibly into the
  weekend. General rainfall amounts of 2 to 4 inches are expected
  the next 72 hours with the highest totals along and south of the
  Interstate 78 corridor. Locally higher amounts are possible across
  the same area as thunderstorms are expected to periodically
  develop.

* A variety of flooding types are all possible within the Flood
  Watch area. First, low-lying and poor drainage flooding is the
  most likely type of flooding to develop. Second, flash flooding
  will be possible under the stronger thunderstorms. Flash
  flooding occurs quicker than other types flooding due to the
  torrential rain thunderstorms can produce in a short amount of
  time. Flash flooding is most likely to occur across urban areas
  where rainfall runoff is maximized and where small creeks and
  streams respond quickly. The rain has to go somewhere and
  eventually leads to larger streams and rivers. This is where the
  third type of flooding is possible. If you live across the
  Passaic, Raritan, and Rancocas basins in New Jersey or the
  Neshaminy, Schuylkill, and Brandywine basins across Pennsylvania
  and Delaware, keep an eye on later forecasts. These forecasts,
  as well as all of our hydrologic forecasts, can be accessed via
  our Advanced Hydrologic Prediction Service website.

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.
