Despite area loss back to average,
2019 is strengthening its position as front runner, but for how long?
Other StuffWeatherGFS over the next 7 days showing temperature anomalies in a temperature anomaly range of +0.5 to +1.7 degrees celsius.
- over the Arctic Ocean itself temperatures a bit above average,
- the CAA, Baffin Bay and Hudson Bay are mostly warm,

The winds described in previous posts seem to have mostly faded away, apart from strongish winds along the Russia shore from the Laptev to the Kara.
A cliff or not a cliffWe are in the period of maximum daily area loss that lasts until late July.
Area losses have ticked up a lot in the last 10 days, but moderating.
Being a five day trailing average, above average area losses should continue for 2 or 3 days at minimum.
A steep downward slope, separating 2019 from 2016 and now from 2012.
