Federal authorities closed a new section of the Gulf of Mexico to fishing on Sunday due to the worst oil spill in U.S. history, extending the restricted zone westward along the Louisiana coast.

The latest order from the National Oceanographic and Atmospheric Administration adds nearly 1,100 square miles of federal waters off Louisiana’s Vermilion Bay to the off-limits zone. The new closure brings the portion of the Gulf closed to fishing due to the massive BP spill off Louisiana to 33.2 percent, NOAA reported.

A ruptured BP well has been spewing tens of thousands of barrels of crude oil into the Gulf every day since late April. The Coast Guard reported earlier Sunday that a shift in weather patterns could send more oil toward sensitive shores in Mississippi and Louisiana.
