otto formed under much the same set of environmental conditions, originating from a similar system about four weeks ago. the old 26-27c rule doesn't work well with hybrids in the subtropics, especially in the cold months. i'd give this feature more account if it were to get a substantial and persistent upper feature at first, as a transitional core warming and deep surface low would require a solid break in the strong westerlies this time of year. recalling how long the nhc sat on otto before classification, i'd say the chances of a classified system are near zero, but should be worth tracking nonetheless.
MM you're as bad as me, rooting for hybrid fishspinners in the off months...
might as well get one, the forecast for snow here at the end of the week turned into a wash. dull dry cold is what i'm getting.
