All vessels shall make immediate preparations to evacuate the RNA if not moored at a facility with an Annual Hurricane Operations Plan.

Port partners and mariners are cautioned that the COTP New Orleans may quickly progress through Port Conditions as the situation develops, so vessel evacuations from the RNAs should be completed as soon as possible.
