Flash flooding risk, heavy rain threaten NYC Monday

NEW YORK CITY - Scattered storms, heavy downpours and flash flooding are possible on Monday afternoon into the evening across the New York City area.

"There's going to be some heavier rain, which does focus more to the north and west, but a lot of that does bleed into the core of the Tri-State by I'd say late this evening into the early overnight hours," FOX 5 NY's Mike Woods said.
