expected in vulnerable areas near the waterfront and shoreline.
* WHERE...In Connecticut, Southern Fairfield, Southern New

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.

depend on how quickly winds turn to the the north. If winds
turn northerly quicker than currently forecast, coastal
flooding magnitude would be lower than predicted and any wave
action minimized.
