321 PM EDT Sun Oct 12 2025
...COASTAL FLOOD ADVISORY REMAINS IN EFFECT UNTIL 8 PM EDT
MONDAY...
* WHAT...1 to 1 1/2 ft, locally 2 ft of inundation above ground
level expected in vulnerable areas near the waterfront and
shoreline for this afternoon, but moreso tonight, and Monday
afternoon high tide cycles.
* WHERE...Southern Fairfield, Southern New Haven, Southern
Middlesex and Southern New London Counties.
* WHEN...Thru 8 PM EDT Monday, around times of high tide.
* IMPACTS...Widespread minor to locally moderate flooding is
expected in the most vulnerable locations near the waterfront
and shoreline. Expect 1 to 1 1/2 ft, locally 2 ft of inundation
above ground level in low lying, vulnerable areas. Some roads
and low lying property including parking lots, parks, lawns and
homes/businesses with basements near the waterfront will
experience shallow flooding.
* ADDITIONAL DETAILS...This forecast has been weighted towards a
reasonable worst case scenario to account for differences in
model depiction of low pressure track and intensity, and provide
a safety margin for planning. Water levels would fall on lower
end or short of current forecast range if winds remain more from
the north versus the northeast.
PRECAUTIONARY/PREPAREDNESS ACTIONS...
If travel is required, allow extra time as some roads may be
closed. Do not drive around barricades or through water of
unknown depth. Take the necessary actions to protect flood-prone
property.

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

MONDAY...
* WHAT...Up to one foot of inundation above ground level in low-
lying areas near shorelines and tidal waterways.
* WHERE...In New Jersey, Gloucester, Camden and Northwestern

* IMPACTS...At this level, flooding begins on the most

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 National Water Prediction Service at
https://water.noaa.gov/wfo/phi for additional water level and
flood impact information for your local tide gauge.
