It does seem to be only the less insightful Canadian model persisting with a local LOW on 17 Oct http://www.meteociel.fr/modeles/geme...mode=0&carte=0 If still there , virtually, tomorrow I'll rerun my app as tonights GEM looks stronger wind in the approaches and channel proper, than this morning run. Not much of a low but it shows that on top of the highest of spring tides, does not need much residual to cause local residential flooding, if not defended against. |

TSR wrote it off just now as dissipated. I think they mean no longer tropical its core is still the same size and doing 90+ kph in places: https://earth.nullschool.net/#curren...-73.983,36.169 https://earth.nullschool.net/#curren...-64.144,24.663 The Spanish may be seeing the end of this run but it could get deep into the Med. I wonder if it intends to wake Sillisea. |

GEM now pushes that 17 oct low more north.
And that was the only model to have a follow-on of bringing ex-Nicole across the Atlantic. So NHC projected upping of her winds to 100mph in her senescence , is keeping her to the west of the Atlantic and expiring over there? |

Perhaps the late strengthening of Nicole, is not yet factored in the models yet, and will punch through that high. |
