    What to Know

    • A First Alert is in effect from noon Thursday to 9 a.m. Friday for heavy downpours and localized flooding in Philly and points south.

    • The remnants of Tropical storm Michael will combine with other moisture and a cold front to bring the potential for heavy rain.

    • Driving could be difficult in areas hit by heavy downpours. Damaging coastal winds are also possible.

    The NBC10 First Alert Weather Team issued a First Alert for heavy tropical downpours packing the potential for localized flooding and potentially damaging winds along the coast.

    The First Alert is in effect from noon Thursday to 9 a.m. Friday from Philadelphia southward through Delaware, South Jersey and the Jersey shore.

    People woke up Friday morning to flooding along roads in South Jersey, including the Black Horse Pike in Williamstown and White Horse Pike in Camden County. The rain, however was pushed off the sea before daybreak.

    “A lot of moisture coming up from the south as a cold front comes in from the west and, in addition to that, we also have what’s left of Hurricane Michael,” First Alert Weather meteorologist Bill Henley said.

    “Even though it’s expected to pass to our south, that’s the center of the storm, the heaviest rainfall will be to the north of that center, which includes parts of Delaware and South Jersey,” Bill said.

    The heaviest of the rainfall came later Thursday evening into early Friday morning. There was also a potential for strong coastal wind gusts.

    Once the storm moves out to sea, much colder air will move in, and will stay with us through the weekend – high temps likely won’t get out of the 50s Saturday -- and all of next week.
