The Cat. 3 hurricane is stabilizing with movement north.

The image shows a central pressure leaving the coastline of Cuba. As soon as Katia dissipated into land, Irma locked into it's water vapor trail to the Arctic Circle. The UNISYS image shows that better.

This is the last image of Katia being connected to the water vapor trail to the north Atlantic.

Up to this point the water vapor feeder system was south of Irma. With the transition into the water vapor heat transfer system to the northeast/north Atlantic; Irma began to move west and north into this water vapor trail.

The very rough air mass over the country was an Arctic insertion into the lower latitudes. While Katia and now Irma were sending hot water vapor to the north Atlantic and the Arctic Circle, the cold air displaced down to lower latitudes.

Hot air rises and cold air sinks. The hot air has to go somewhere. There is not infinite room for more and more hot air over the Arctic. The cold air sinks to lower latitudes as the hot air is transferred to cool it down. The climate over the Arctic Ocean is vastly different from 20 years ago. The heat transfers are instrumental in that climate change.
