The first Atlantic hurricane of the year is bearing down on the US Gulf Coast. Hurricane Isaias is forecast to strengthen to category three before making landfall later Friday into Saturday, according to BBC Weather reporting. The storm arrives after months of unusual quiet across the basin. El Niño has suppressed tropical activity this season, keeping the Atlantic unusually calm through early autumn. That pattern is breaking now. Isaias represents the kind of rapid intensification forecasters watch for late in the season, when a single system can upend weeks of relative peace. The Gulf Coast now faces a narrow window to prepare. Category three hurricanes bring sustained winds of at least 111 miles per hour, capable of catastrophic damage to structures and infrastructure. Residents in the projected path have hours, not days, to secure property and finalize evacuation plans as Isaias churns closer to shore.
