Two disturbances are approaching our area and will combine off the Middle Atlantic Coast Monday, causing a strong Nor’easter to form. This Nor’easter will then move northward off the NJ Coast, pulling moisture back into our area.

It will also become windy Tuesday morning with gusts up to 40 mph possible, especially in Southern sections and on Eastern Long Island.
