There has been a strong negative velocity potential(divergent irrotational part of the total wind field) in the North Pacific in the last one week -


and it looks like it has spawned off a East Pacific Hurricane.


The Low(967 hPA) is centered around 50 N and 140 W and NWS expects it to move into the Gulf Of Alasks.

The Northern Pacific region has had a strong negative OLR anomaly for the past one week.

You are right it is an extratropical cyclone but with hurricane like winds. When the warning was issued the speed was 64 knots same threshold as a hurricane.

Paul - if this post needs to be moved to another forum and not tropical please go ahead and do it. I did not see a category for extratropical cyclone
