For a limited period beginning June 15, 2008, NOAA RNCs will not be updated for Notices to Mariners or for new editions of the nautical charts. This temporary interruption of service is due to a change in RNC production systems. Full RNC service will resume when reliable production is restored. In the interim, continuously updated NOAA Print on Demand charts (www.OceanGrafix.com), traditional printed charts, and free Electronic Navigational Charts and updates will continue to be available.
