Thus It Ends For Nadine

Nadine's long, onerous, entertaining journey across the Atlantic and through a couple of loops is finally over. I think.

Nadine transitioned to a nontropical low for the second time in its life today; this time, absorbed into a frontal boundary associated with a larger nontropical low that's centered over the Central Atlantic.  Nadine's 88 advisories -- and 21 3/4 days of life as a tropical cyclone of any note rank it fifth on the list for longevity in the Atlantic, with it ranked second as longest lasting tropical storm or higher system (21 1/4 days).

Nadine, located to the north of the Azores Islands, continues to push northward and will continue to lose its identity as it dances around the larger storm system to its west.

Farther south, Oscar became the season's 15th named system yesterday but will not last as it has begun to feel the effects of the larger nontropical system to its north.   This storm is already moving northeast, pulled in that direction by southwesterly upper level winds and will gradually get absorbed by the cold front that also absorbed Nadine within the next 36 hours or so.

Down the line, this large scale storm system should gradually pinwheel across the Central Atlantic and eventually impact Europe early next week with wind and rain.   It will weaken a fair bit between now and its European date but it will contain tropical moisture from Oscar and also whatever leftovers from Nadine are still around.  The result will be more heavy rain and potentially more flooding issues for the UK.
