Coastal Flood Advisory issued February 2 at 4:16AM EST until February 2 at 1:00PM EST by NWS Mount Holly NJ

Effective: Mon February 2, 2026, 4:16 AM
Expires: Mon February 2, 2026, 1:00 PM

* WHAT...Up to one foot of inundation above ground level expected in low-lying areas near shorelines and tidal waterways. * WHERE...Ocean, Atlantic, Coastal Atlantic, Coastal Ocean and Southeastern Burlington. * WHEN...Until 1 PM EST this 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. * ADDITIONAL DETAILS...Ice from the back bays could get pushed onshore during high tide, and flood waters could freeze on roadways, further complicating impacts.

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.

The times presented here are based upon the solunar theory, which is the idea that the movements of fish and other animals are affected by the location of the sun and moon. The major periods are believed to be the times of the greatest animal activity and occur when the moon is directly overhead or underfoot (lunar transits). The minor periods also see increased activity and occur when the moon is rising or setting. The strongest activity occurs during full or new moons, and the weakest during quarter or three quarter moons. This is indicated by the Action Rating.
