At least one oil and gas platform in the U.S. Gulf of Mexico was shut on Monday and Florida ports imposed restrictions on vessel navigation as Hurricane Milton rapidly intensified. Most energy infrastructure on the U.S. Gulf Coast, including oil and gas production facilities, liquefied natural gas (LNG) plants, and refineries, is expected to be out of the storm's path. However, the closure of terminals could temporarily disrupt exports and imports. Florida was the sixth largest state exporter of goods last year, according to the Office of the U.S. Trade Representative. Meteorologists forecast 10 to 15 feet (3.05 to 4.57 meters) of storm surge, 120 mph to 140 mph wind gusts, and say more than 2 feet of rain is possible along the Florida Gulf Coast in the area where Milton makes landfall, probably near Tampa. President Joe Biden approved an emergency declaration for Florida. The U.S. National Hurricane Center said on Monday the storm will approach the west coast of the Florida Peninsula by Wednesday after becoming a powerful Category-5 hurricane on the Saffir-Simpson scale. Electricity provider Duke Energy said it was mobilizing about 10,000 responders in Florida as it prepared for more than 1 million power outages associated with Milton. U.S. energy producer Chevron said on Monday that all staff from its Blind Faith platform in the Gulf were transported and the facility had been shut. Blind Faith, located 160 miles (257.5 km) southeast of New Orleans, is Chevron's deepest water development.
