#ClimateChangeNow Update THREAD.

The unusual, unpredictable and #ExtremeWeather of #HurricaneIAN is still continuing in the North East of the US. The remnant low has strengthened and remains parked off the Maryland coast.

This storm has now spent nearly a week over the US.

Last night I posted a fairly discursive thread looking at the Tropical Atlantic, and some threats in the long range GFS forecast - including the threat posted by the remnants of #HurricaneIan

Here we are looking in particular at the stationary low pressure center off the coast of Maryland (Top Left) in the animation above. The impacts are becoming more significant now as the remnants of #IAN - back over the Atlantic are strengthening again.

Last 12 hours in DC.

And last 12 hours in the broader Tri-State Area - NYC, New Jersey, Long Island, Conneticut and Eastern Pennsylvania.

Heres a 90 hour (4 day) forecast for the North East Seaboard. The storm can be seen bottom right, and it looks like it is going to get worse before it is swept away to the east.

The associated rain forecast shows 48 hours rain in New York.

Its not forecast to be particularly heavy fortunately. But it is astonishing that #HurricaneIAN is continuing to be as unpredictable as it is.

Going back to the original animation in this thread, a feature worth noticing is the atmospherica river (due south of Long Island coming up over the Atlantic) which is continuing to feed the storm with warm tropical energised water.
