Friday, May 18th: Flood Watch Continues, Coastal Flood Advisory Issued for Avalon

The National Weather Service has continued the Flood Watch and has now issued a Coastal Flood Advisory for the Borough.  The Flood Watch is in effect from now through Saturday afternoon, and the Coastal Flood Advisory is in effect from Friday, May 18th at 9:00pm through Saturday, May 19th at 2:00am.

A low pressure system will continue to produce rain in our region through Saturday morning.  The rain could be heavy at times which could cause some street flooding.  Never drive on a flooded street as this puts you, and your vehicle, in danger.  The Coastal Flood Watch means minor tidal flooding could occur at time of high tide late Friday evening; high tide at the Townsend’s Inlet Bridge will occur at 11:21pm Friday.

Streets that typically flood during coastal flood events may see some water.  Continue to exercise caution while driving.

Here is the text of the Flood Watch and the Coastal Flood Advisory issued by the National Weather Service:

The National Weather Service in Mount Holly has issued a Coastal
Flood Advisory, which is in effect from 9 PM this evening to 2 AM
EDT Saturday.

* LOCATIONS...The Atlantic coastal waters of New Jersey and
  Delaware and the adjacent areas near lower Delaware Bay.

* COASTAL FLOODING...Minor tidal flooding expected.

* TIMING...The high tide between roughly 11 p.m. and 1 a.m. High
  tide will occur several hours later across the back bays.


A Coastal Flood Advisory means that minor tidal flooding is
expected. Minor Tidal flooding often results in some road
closures. Usually...the most vulnerable roadways will flood.

Do not leave your vehicle at a location that is prone to tidal
flooding. Do not drive your vehicle through flood waters. The
water may be deeper than you think it is. You will be putting
yourself in danger and your vehicle may be damaged...leading to
costly repairs.

Visit the Advanced Hydrologic Prediction Service at for additional water level and flood
impact information for your local tide gauge.

Flood Watch
Flood Watch
National Weather Service Mount Holly NJ
342 AM EDT Fri May 18 2018


The Flood Watch continues for

* Delaware, northeast Maryland, most of New Jersey, and portions
  of southeast Pennsylvania.

* Through Saturday afternoon

* Periods of moderate to heavy rain will move into southern New
  Jersey and the Delmarva this morning. Periods of moderate to
  heavy rain will move into Delmarva late tonight through Saturday
  morning, then expand northward into southeastern Pennsylvania
  and New Jersey Saturday afternoon and night. Additional rainfall
  amounts of 1 to 4 inches are expected over the next 72 hours
  with the highest totals occurring in Delmarva and far southern
  New Jersey. Locally higher amounts over 5 inches are possible in
  slow-moving thunderstorms.

* A variety of flooding types are possible. Low-lying and poor
  drainage flooding will be the most common type of flooding to
  develop. Flash flooding will also be possible if thunderstorms
  repeatedly move over the same locations, especially in urban
  areas where rainfall runoff is maximized and where small
  creeks and streams respond quickly. Flash flooding occurs
  quicker than other types flooding due to the torrential rain
  thunderstorms can produce in a short amount of time. Several
  days of excessive runoff will eventually lead to a risk of
  flooding in larger streams and rivers though the extent of the
  flooding will depend on where the heaviest rain falls.


A Flood Watch means there is a potential for flooding based on
current forecasts.
