2017 Tropical Outlook: The Weather Company Bumps Up Tropical Atlantic Forecast Numbers because of Warmer Tropical Atlantic and Fast Start to Season

ANDOVER, Mass. (August 22, 2017) — In its fifth and final seasonal tropical forecast for the North Atlantic basin for the 2017 season, The Weather Company, an IBM Business, has increased its forecast numbers for the full season from 15/8/3 to 17 named storms, 9 hurricanes, and 4 of which are major hurricanes. These numbers include the 8 named storms and 2 hurricanes to date (as of August 22). The current forecast numbers are now higher than both the long-term 1950-2016 normals of 12/7/3 but match the recent “active period” (1995-2016) normals of 15/8/3.

According to Dr. Todd Crawford, chief meteorologist at The Weather Company, “We are already off to a fast start to the 2017 tropical season. As the positive ocean temperature anomalies in tropical Atlantic continue to increase and the model trends lean more towards La Nina conditions heading through the peak of the season, we have no choice but to raise our numbers further. There will likely be significant sub-seasonal fluctuations in activity levels, such that the peak of the season may be less active than normal but that both sides of the peak will be unusually active.”

The Weather Company provides customized weather information to global commodity traders via its industry-leading WSI Trader Web site. This is the last tropical outlook for the 2017 season.
