The remnants of Hurricane Ian, the Category 4 storm that devastated Florida before hitting the Carolinas last week, soaked the Philadelphia region with rain most of the weekend and into Monday, resulting in a flood advisory to be issued for coastal areas.
Windy conditions and rain are expected to continue through Tuesday, according to the National Weather Service's forecast. Due to all the precipitation, a coastal flood advisory is in effect from Monday at 1 p.m. through Tuesday at 9 p.m.
The advisory covers Philadelphia, Delaware and Lower Bucks counties in Pennsylvania, and Gloucester, Camden and northwestern Burlington counties in New Jersey. The lingering remnants of the Ian system changed from tropical to subtropical storm before reaching this area.
At this level of flood advisory, the Delaware River could flood vulnerable roads, resulting in partial or full road closures. The NWS says motorists traveling in these areas should allow extra time to reach their destination and warns people never to drive around barricades or through standing water where the depth is unknown

The Schuylkill River is not expected to reach levels that threaten flooding the communities along its banks, like Manayunk. With all the rain Sunday, the Schuylkill crested at more than 7 feet, and by Monday morning it was down to just more than 6 feet. The Schuylkill River floods low-lying areas along its banks when it reaches 10 feet.
Storms from Hurricane Ian affected parts of the Jersey Shore and Delaware, where coastal flood warnings also are in effect.
At the Jersey shore, roads in low-lying areas, like parts of Landis Avenue in Sea Isle, were flooded, and the Ocean City School District opted to dismiss students early Monday due to possible flooding.
