Hurricane Elsa is an active strong tropical storm currently impacting Florida and threatening portions of the Southeastern United States. The fifth named storm and first hurricane of the 2021 Atlantic hurricane season, Elsa was first monitored by the National Hurricane Center (NHC) as a tropical wave on June 29, and was designated as a Potential Tropical Cyclone on the next day, while moving westward across the Atlantic. After showing signs of a better-defined low-level circulation, the cyclone was upgraded into a tropical depression by 03:00 UTC on July 1, then further to Tropical Storm Elsa a few hours later. Upon its naming, Elsa received widespread social media attention, due to the storm's sharing its name with Elsa from Disney's Frozen franchise. After undergoing a rapid intensification, at 10:45 UTC on July 2, Elsa was upgraded to a Category 1 hurricane. Elsa is the strongest July hurricane in the eastern Caribbean Sea since Hurricane Emily in 2005, and also the fastest-moving Atlantic tropical cyclone recorded undergoing rapid intensification in that part of the Atlantic. On July 3, Elsa weakened back into a tropical storm before slowing down by July 4, as it passed just north of Jamaica. On July 5, Elsa made landfall in Cuba, before emerging into the Gulf of Mexico early on the next day.
