Correct me if Im wrong but doesnt an ULL have a extremly low chance of making it to the surface..sorry if that sounded newbish...Im trying to learn on this great site....

95% or more never become surface lows
this one is differnt on sat pics. you can clearly see some outflow over it

Some seasons about 30 to 40 percent of the seasons tropical cyclones are formed from upper level lows...Alex was formed by one this year...So was the pest named Kyle. So yes upper level lows do form into tropical cyclones. What needs to happen is the upper low needs to cut off. Then form convection over the upper low. Over time that convection will form a low level low pressure under that upper low. Then the upper low will move away. Then a upper high forms over the upper low. So yes it could very well be a tropical cyclone.

They always have the chance to work their way down to the surface. GTHis would most definitely move North and out to sea.

As you said this year Alex, but also Gaston and Hermine were of subtropical origins, but the last two mentioned where like brother-sister since they developed from the same parent, a cold front.

TCs can form from ULL but it takes FOREVER!! Most start out as Subtropical before transiting to purely tropical systems

I agree, and I want to say that for me the most astonishing and interesting of those ULL becoming tropical lows after the Perfect Storm is last year Hurricane Erika. It traveled thousands of miles to achive its goal.
