In Essex County, the Garden Staet Parkway was closed for a short time because of flooding between Exits 145 and 149.
Traffic had to be diverted and quickly backed up.
The Parkway reopened in both directions at about 3 p.m. after disabled vehicles were removed and water was plowed off the road.
Traffic also slowed to a crawl in Hackensack due to the rising flood water.
Five people stuck in two cars were rescued, but the water receded quickly.
There were no injuries.
