2017 Tropical Outlook: The Weather Company Says Latest Data Now Suggesting Season Will Be More Active than Originally Thought

ANDOVER, Mass. (May 27, 2017) — In its second seasonal tropical forecast for the North Atlantic basin for the 2017 season, The Weather Company, an IBM Business, now expects a total of 14 named storms, 7 hurricanes, and 3 major hurricanes. These numbers include Tropical Storm Arlene, which formed in April.  This is an increase relative to the original April forecast numbers of 12/6/2. The current forecast numbers are more than the long-term 1950-2016 normals of 12/7/3 but slightly fewer than the recent “active period” (1995-2016) normals of 15/8/3.

According to Dr. Todd Crawford, chief meteorologist at The Weather Company, “There has been a clear trend over the past month towards warmer North Atlantic ocean temperatures and a less bullish view on El Nino development/magnitude, both of which favor a more active 2017 Atlantic tropical season than originally thought.  Dynamical model forecasts are also more aggressive this month relative to last. The big North Atlantic blocking in May has favored continued increases in Atlantic water temperatures, which suggests that we may need to move our numbers up a bit more in our June update.”
