"The last time we had a strong El Niño event followed by a La Niña event in the same year, in 1998, we had a Atlantic hurricane season 40% above average in activity, with 14 named storms, 10 hurricanes, and 3 intense hurricanes. The season was relatively late-starting, with only one named storm occurring before August 20. I'm thinking this year's season may be similar, though four or more intense hurricanes are a good bet due to the record warm SSTs (surface sea temperatures)."
Above are the storm tracks from 1998 and you can see it was a busy year. Two of those storms came through our area - Earl, a poorly formed storm that went from the gulf coast inland to the east coast, and Bonnie, which came ashore as a hurricane, became a tropical storm and then re-intensified to become a hurricane as it moved up coastal North Carolina and Virginia.
