Exxon Mobil Corp. had said it is cutting output at its Hoover production platform in the Gulf of Mexico ahead of the storm. The company’s also working on plans to evacuate staff in stages from offshore facilities that will be in the path of the storm. Royal Dutch Shell Plc shut production at its Perdido platform and evacuated the facility.

Anadarko Petroleum Corp. said earlier this week it is removing nonessential staff from some production platforms in the Gulf of Mexico in response to weather conditions. Cheniere Energy Inc. activated the severe weather team at its Sabine Pass LNG export terminal in Louisiana.
