The National Hurricane Center said Monday it is tracking a system in the Gulf of Mexico that could become Tropical Storm Helene in the coming days.

U.S. oil producers on Monday were scrambling to evacuate staff from Gulf of Mexico oil production platforms as forecasters predicted the second major hurricane in two weeks could tear through offshore oil producing fields.

Forecasters warned residents along Florida’s Gulf coast of potential Hurricane Helene, which is expected to form in the next 48 hours and track toward an area somewhere between Tampa and Pensacola late in the week.
