The lull expected by meteorologist Richard Lewelling gave way to another round of storms on Monday afternoon in North Jersey that caused some locally heavy rain prompting a Flood Advisory for parts of Bergen. Passaic, Morris, Essex and Hudson counites.

Delays of 1-hour, 15-minutes on arrivals have developed at Newark Liberty Airport according to, due to the storms.

"Some of those storms could have damaging wind gusts, large hail, frequent lightning and locally heavy rainfall," explains Lewelling, who says a "conveyor belt of disturbance will keep New Jersey unsettled with daily storm chances over the next 7 days."

Sunday's weather also caused some problems for swimmers, where the beaches were crowded and rip currents were active. There were two rescues in Seaside Heights according to the Press of Atlantic City, which also reports rescues at Long Beach Island, Harvey Cedars, Barnegat Light, Surf City and Atlantic City.
