Coastal Flood in Southern New London, Connecticut

Moderate coastal flooding occurred at the New London NOS tidal gauge, with water levels above the moderate threshold of 6.0 ft MLLW from 854 AM EST to 1148 AM EST, and a peak water level of 6.6 ft MLLW from 1000 AM EST to 1112 AM EST.

Strong low pressure shifted northeast through the eastern Great Lakes on January 13, 2024, sending a warm front through during the morning hours, followed quickly by a cold front. Strong winds produced by this system, combined with peaking high astronomical tides associated with a recent new moon, produced widespread moderate coastal flooding along the southern Connecticut coastline.
