Watches & Warnings

Flash Flood Watch, Coastal Flood Advisory
Issued: 4:20 PM EDT Jul. 21, 2018 – National Weather Service

... Flash Flood Watch remains in effect through late tonight...

The Flash Flood Watch continues for

* northeastern Maryland, Delaware, southeastern Pennsylvania,
southern New Jersey and parts of central New Jersey.

* Through late tonight.

* Moderate to locally heavy rain continues to overspread the area
late this afternoon. The risk for poor drainage flooding and
flash flooding increases this evening as a band of heavy
rainfall lifts northward through the region. Rainfall amounts
of around 2 inches are forecast with much of the rain expected
to fall over a period of only a few hours this evening. Locally
higher amounts of 3 to 4 inches possible, especially across
northeastern Maryland and southern Delaware.

* Excessive rainfall in a short amount of time can lead to flash
flooding. Urban areas, locations along small streams and
creeks, and areas of poor drainage are most vulnerable to
flash flooding.

Precautionary/preparedness actions...

A Flash Flood Watch means that there is the potential for flash
flooding which can be life-threatening. Heavy rain is expected to
occur over a short period of time. Rapidly rising flood waters
may quickly inundate roadways and areas of poor drainage. Streams
and creeks could leave their banks, flooding nearby properties.

Please monitor the forecast, especially if you live in a location
that is prone to flooding. Be prepared to take action if a Flash
Flood Warning is issued for your area.




320 PM EDT Sat Jul 21 2018

... Coastal flood advisory remains in effect until 9 PM EDT this
evening...

* locations... tidal areas of Cumberland and Salem counties in New
Jersey, and Kent and New Castle counties in Delaware.

* Timing... high tide along the middle and upper parts of Delaware
Bay, and on the far lower part of the Delaware River occurs
between about 5 PM and 8 PM this evening.

* Coastal flood impacts... up to one half foot of saltwater
inundation above ground level in low-lying areas near shorelines
and tidal waterways in the affected counties. Some roadway
flooding is expected.

* Waves... around 3 feet on the middle and upper parts of
Delaware Bay.

Precautionary/preparedness actions...

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
water.Weather.Gov/ahps for additional water level and flood
impact information for your local tide gauge.
