Grace has formed in the beginning of October near the 40th parallel north (around 20-25° ouest, north-east of the Azores islands) from a phasing between an old frontal system and an upper level forcing. This mechanism of cyclogenesis has not to be compared to tropical cyclogenesis and is very common for mid-lattitude disturbance.
