Mid-August through late October historically is the most active period of the Atlantic basin tropical storm season (June 1-November 30, for the Atlantic Ocean, Caribbean Sea, and Gulf of Mexico), and late August 2016 is corresponding to that history. Three tropical cyclones–Hurricane Gaston and two tropical depressions–were in the basin on the afternoon of August 30, 2016, as seen in the image below, the 2-day Graphical Tropical Weather Outlook from the National Hurricane Center (accessed online at http://www.nhc.noaa.gov/gtwo.php?basin=atlc&fdays=2 at 3:30 p.m. EDT on 8/30/16). According to the Hurricane Center, “the outlook is updated at approximately 2 AM, 8 AM, 2 PM, and 8 PM EDT from June 1 to November 30, with special outlooks issued at any time as conditions warrant. The graphic displays all currently active tropical cyclones, and disturbances with tropical cyclone formation potential over the next 48 hours.” Below the graph is the Hurricane Center’s outlook text as of 2 p.m. EDT on Aug. 30.
