Hurricane Isaias strengthened from a tropical storm Thursday, October 8, and is moving toward the U.S. Gulf Coast with maximum sustained winds of 75 mph. The National Hurricane Center reported Thursday that the storm is positioned approximately 460 miles southwest of the mouth of the Mississippi River, with landfall projected between Friday evening and early Saturday.
The cyclone formed Wednesday in the eastern waters of Mexico during an Atlantic hurricane season that has remained unusually quiet due to a strong El Niño. According to the National Weather Service, Isaias tied a 121-year-old record for the latest-forming first hurricane of the season, a milestone last set on October 8, 1905.
Florida Governor Ron DeSantis declared a state of emergency for 25 counties, while Alabama Governor Kay Ivey issued a similar declaration for 40 counties. A hurricane warning is in effect from Ocean Springs, Mississippi, to the Bay/Gulf county line in Florida. Additionally, storm surge warnings extend from the mouth of the Mississippi River to Yankeetown, Florida, as forecasters warn of life-threatening surges.
The storm is impacting regional energy production. Off-shore oil and gas producers in the Gulf, which provides nearly 15 percent of U.S. annual crude, have halted approximately 25 percent of oil production. This suspension removed roughly 511,000 barrels a day from the market as of Wednesday. The Marine Minerals Administration reported that eight of the Gulf's 371 manned platforms were evacuated. Jim Burkhard of S&P Global Energy noted that while production cuts are affecting markets, a primary concern remains the storm's potential impact on coastal refineries.
The hurricane may also disrupt regional travel and events. Forecasters indicated the storm could affect Saturday's college football game between Georgia and Alabama, which President Donald Trump is scheduled to attend. Inland portions of the Southeast, including the Tennessee Valley and the Carolinas, could see 1 to 5 inches of rain through early next week. The storm follows historical precedents in the region, including Hurricane Camille in 1969 and Hurricane Katrina in 2005. Landfall is currently expected late Friday, October 9, or early Saturday, October 10.
