Arctic Sea Ice is not freezing In October for the first time since measurements began, now having an unknown effect on weather development towards Winter

Arctic sea ice melt season usually lasts from March till September. After reaching the minimum extent in September, sea ice starts to grow back in October. But this year, the growth is much slower than last year, with almost no growth in some places. How did this unusual situation happen and can it mean something for the weather towards Winter 2020/2021?

Growth has obviously begun since mid-September, but the rate was rather weak and is not increasing with time, evident by the recent daily increase rate on the image below. At this point, the daily growth should slowly increase over time, but we can see the daily growth area is not increasing and has rather been almost decreasing over time.
