Federal regulators say Tropical Storm Fay has not caused any production shutdowns of oil and natural gas drilling in the Gulf Mexico.

The storm’s center crossed over Key West on Monday and was moving north along Florida’s southwestern coast.

Minerals Management Service spokeswoman Caryl Fagot says some non-essential personnel have been evacuated from rigs in the eastern Gulf but there were no reports of evacuations that would halt production.

Shell Oil Co. says it evacuated 425 workers but there were no production interruptions. If the storm stays on its current track to make landfall in Florida, no more evacuations are expected.
