The National Weather Service has issued a Coastal Flood Warning for parts of southern Connecticut and southeastern New York from Friday evening through Sunday evening. Inundation of two to three feet above ground level is expected in vulnerable shoreline areas.

The National Weather Service office in Upton, New York, issued the warning at 5:27 AM EDT on September 25. The warning is in effect from 6:00 PM EDT on Friday, September 25, until 6:00 PM EDT on Sunday, September 27.

Forecasters report that moderate flooding will occur over multiple high tide cycles starting Friday night and continuing through Sunday. The worst flooding is expected during the daytime high tide cycles on Saturday and Sunday.

Widespread flooding is expected near waterfronts, shorelines, tidal rivers, and bays. Impacted areas will likely include roads, parking lots, parks, lawns, and homes or businesses with basements situated near the waterfront.
