Wow, never seen this in a discussion before:
These winds in combination with even
colder sea surface temperatures along the forecast track should
result in weakening and extratropical transition. However...we have
been expecting such transition but there are no indications of this
happening yet.

People think hurricanes can't sustain themselves in 21-22 Sst's but Vince and Epsilon have proven us wrong. They may have the extra energy because how insane this season has been. Its just another way of mother nature to surprise us.

I use to think 26c was the limit, boy that was way wrong.

That's true. Epsilon is around the 22 degrees Celsius (71.6 F)isotherm.

so if a hurricane can live in those waters, then in the middle of summer when New Jersey has 22-24 Sst's, a hurricane can hit us instead of weaken

It's possible, but fortunately, not all hurricanes respond the same way to changes in their environment. Also, Epsilon's extratropical history could be helping the hurricane to sustain itself in cooler temperatures.

If a major hurricane is possible in NYC, a hurricane here is quite possible
But Epsilon is different just like Vince. It's like the crazy season itself is helping Epsilon

I can not emphatically say that space weather has effected Epsilon but I also believe that you can not say that it has not. So my objective is to try and talk about what I have observed over the years and to try and show/teach people this methodology.

I am trying to make it as simple as possible by giving out URL's to access solar wind and particle readings. I will continue to point things out when I have time but I also feel that if you really think that I might be on to something then you may want to take the next step. I would suggest that you read more about space weather. This would help you educate yourself more about the subject matter.

This winter may be a good time to do this while the tropics are quiet.

Epsilon isn't completely unprecedented. Tropical-style cyclones are occaisionally observed over colder waters. Fundamentally a tropical cyclone is a heat exchanger between warm surface and cold high-altitude air. If the high-altitude air is colder that can make up for chillier water, and I'll bet high-altitude air is pretty darn cold in December over the temperate Atlantic.

Given that the heat potential should be generally favorable out of the tropics, the puzzle is probably more of why such things are rare. Dr. Grey has suggested that the key element in tropical cyclones is moist mid-level air (permitting instability throughout the air column; dry air is generally fairly stable since it need a much higher temperature gradient to be unstable). Perhaps that's less common out of the tropics.

Epsilon according to this afternoons SSD dvorak sat estimates is a little more stronger.

I think Epsilon is making a bee-line for warmer water south, doesn't like the water temp it's approaching. :D
