2017-18 Arctic cyclone season

The 2017-18 Arctic cyclone season is an upcoming event in polar cyclone formation over the Arctic basin. The season will officially begin on October 15 and end on January 7, 2018, with the start date being moved up to October 15, 2017 due to the recent uptick in early-season activity. This season will resume the same naming list as the 2015-16 season two years earlier, with the exception of the retired name Noel.

The Bob Nekaro Weather Center (BNWC) monitors the basin including the Hudson Bay, the Baffin Bay, the Labrador Sea, the Atlantic north of 50 degrees North, and the North Sea.

Seasonal Forecasts
On July 21, the BNWC issued their initial seasonal forecast for the 2017-18 season, predicting below average activity with 5-8 named storms, 2-4 polar cyclones and 1-2 major polar cyclones. The prediction was based on higher-than-normal wind shear over the Arctic. On August 10, the Garfield International Hurricane Center released its forecast, predicting below-average activity with 5-6 named storms, 2-4 polar cyclones and 0-2 major polar cyclones. That same day, the Collin D Meteorological Center released its forecast, predicting 7-9 named storms, 2-4 polar cyclones, and 0-3 major polar cyclones. The BNWC issued an updated forecast on September 11, raising their numbers slightly as wind shear was not expected to be as strong in the Arctic basin as expected two months ago. That same day, HTMC released its prediction, predicting below average activity with 7-11 named storms, 3-5 polar cyclones, and 1-3 major polar cyclones. The NKWC released their prediction that day as well, predicting 11 named storms, 6 polar cyclones and 2 major polar cyclones. Floyd Meteorological Center also released their prediction on September 11, predicting slightly below average activity with 9-12 named storms, 3-7 polar cyclones and 0-3 major polar cyclones. On September 13, GIHC updated their forecast, raising their numbers to 9-12 named storms, 4-7 polar cyclones, and 1-4 major polar cyclones.
