The Hudson County Office of Emergency Management said Monday that "the best chance of strong storms is north of Interstate 195 with the weather service noting in its morning forecast discussion that the heaviest rain could fall overnight." NWS officials also said that the "greatest risk of flash flooding exists in areas that received heavy rain late last week."

The storm could also bring damaging wind, with gusts that could exceed 58 mph. Those winds have the potential to damage trees and power lines, possibly causing scattered power outages.

A warm front is to blame for the rain in the area, but the amount of rain also hinges on the movement of that front, according to the NWS. If the front sinks south quickly, rainfall could be less than the 1 to 3 inches projected, but if it holds position over the area, showers and storms will likely stay longer, leading to a greater chance of "significant rain and flash flooding."

Here's the latest forecast:
