...COASTAL FLOOD ADVISORY REMAINS IN EFFECT UNTIL 2 AM EDT 
THURSDAY...

* LOCATIONS...Tidal areas of Kent County.

* TIMING...Until 2:00 AM Thursday.

* COASTAL FLOOD IMPACTS...Minor tidal flooding is expected. Up to
  one half foot of inundation above ground level is possible in 
  low-lying areas near shorelines and tidal waterways. Some 
  roadway flooding is 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.

Time of high total tides are approximate to the nearest hour.
