A string of hurricanes has formed and is heading towards the Eastern US. This "train" of storms could become an extreme weather event.

According to satellite data gathered by the National Atmospheric and Oceanic Administration (NOAA), a marine heatwave (anomaly) in August increased sea surface temperatures in the western North Atlantic. The ocean was significantly warmer than normal when the typically chilly waters were running as much as 9-10F degrees above average.

One storm has now been named as a dangerous hurricane, Florence, with its storm track projected directly towards the mid-Atlantic states. Warmer water temperatures allow for higher atmospheric water vapor carrying capacity and Florence could undergo the process of 'bombogenesis' when the storm intensity increases very rapidly in a 24 hour period.

Climate change models consistently predict that as atmospheric and ocean temperatures increase, storm intensity is amplified. A major "train wreck" of multiple hurricanes could be in the making soon. It's time to watch out!
