above ground level in low lying, 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.

* SHOREFRONT/BEACH IMPACTS...Breaking waves of 3 to 6 ft, along

Splashover over seawalls and overwashes where dune structures
are compromised may locally exacerbate flooding of roadways and
vulnerable structures behind protective dunes.

flooding is possible for the Sunday afternoon high tide cycle.
