It is the second time in three years the event has been cancelled in similar circumstances.
Only one race went ahead on Saturday - the Supersport, which was won by Michael Dunlop.
Even that race was cut short from five laps down to two.
A message on the event's official Facebook page said: "The race organisers have given in to the inevitable and the Vauxhall International 2013 North West 200 road races have been abandoned."
Police said all roads have reopened to the public.
Ballymoney rider Dunlop took the Supersport title after the race was stopped two laps in and decided over quickest lap times.
Bruce Anstey of New Zealand took second place and Lee Johnston third.
The race was earlier delayed due to the heavy rain and an oil spillage on the track.
Victory for Dunlop made it four out of four for Northern Ireland riders at the north coast event this year.
