...COASTAL FLOOD ADVISORY IN EFFECT UNTIL 11 PM EDT THIS
EVENING...

* WHAT...For the High Surf Advisory, large breaking waves up to 8
  feet. For the Coastal Flood Advisory, up to one half foot of
  inundation above ground level expected in low-lying areas near 
  shorelines and tidal waterways. For the High Rip Current Risk, 
  dangerous rip currents.

* WHERE...The Atlantic coast of Sussex County in Delaware.

* WHEN...For the High Surf Advisory, until 6 PM EDT Wednesday. 
  For the Coastal Flood Advisory, until 11 PM EDT this evening. 
  For the High Rip Current Risk, through Wednesday afternoon.

* IMPACTS...At this level, flooding begins on the most vulnerable
  roads in coastal and bayside communities, and along inland tidal
  waterways. Some partial or full road closures are possible.
  Dangerous swimming and surfing conditions and localized beach
  erosion are expected. Rip currents can sweep even the best 
  swimmers away from shore into deeper water.

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.

Inexperienced swimmers should remain out of the water due to
dangerous surf conditions.

Swim near a lifeguard. If caught in a rip current, relax and
float. Don't swim against the current. If able, swim in a
direction following the shoreline. If unable to escape, face the
shore and call or wave for help.

TONIGHT...

* WHAT...Up to one foot of inundation above ground level in low- 
  lying areas near shorelines and tidal waterways.

* WHERE...The extreme upper portion of Delaware Bay and the tidal
  Delaware River down from the Commodore Barry Bridge area.

* WHEN...Until midnight EDT tonight.

* IMPACTS...At this level, flooding begins on the most 
  vulnerable roads along tidal waterways. Some partial or full 
  road closures are possible.

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.
