A storm expected to make landfall Saturday could bring a foot of flooding to shoreline communities in Connecticut.

The National Weather Service issued a coastal flood advisory in southern Fairfield and New Haven counties, starting Saturday afternoon.

“Shallow flooding is expected in the more vulnerable locations near the waterfront and shoreline. Some roads and low-lying properties including parking lots, parks, lawns, and homes and businesses with basements near the waterfront will experience shallow flooding,” the NWS said.

The rough weather could result in breaking surf up from one to three feet, which could result in beach erosion and wave splash-over on shoreline roads and property, the NWS said.

The advisory is in effect from noon to 3 p.m. Saturday.
