déjà vu: How Beaufort sea early open water becomes important much later

NOAA HRPT latest visual animation Mainly April 5, 2017.   Beaufort sea water arises from a short winter slumber,  with sea ice measured quite new, about 1 meter thick,  something easily manipulatable by clockwise winds from a small 1030 mb High pressure system.  

2013-2014-2015-2016 and 2017 NASA EOSDIS gives foresight,  we know that 2013-2015 had lesser sea ice Minima extents in September.  We also know 2016 had a very long lasting High Pressure system already raging by April 5.  However, 2017 has the thinner sea ice with similar breaking open sea water as with 2016.  From this vantage point,  we can clearly  make 2017 potentially in league with 2016 early Beaufort sea warming equal or worse by thinner grayer sea ice,  it will not take much wind action to disintegrate the Beaufort pack,  20 degree high solar ray absorption by sea water, likely quite warmer,  does look good for a long boating season .  WD April 6, 2017
