A non-tropical low developed along a dissipating stationary front on September 16 in the central Atlantic and drifted north-northeastward.[43] The National Hurricane Center classified it as Tropical Depression Eleven on September 17 about 710 mi (1,150 km) east of Bermuda, and initially the depression did not have significant deep convection.[44] A wind report early on September 18 indicated the depression intensified into Tropical Storm Josephine. The storm continued generally northeastward, steered between a subtropical high to the northeast and a frontal system approaching from the west.[45] Josephine maintained a well-defined circulation, but its deep convection remained intermittent.[46] Early on September 19 the storm began being absorbed by the cold front, and as a tropical cyclone its winds never surpassed 40 mph (75 km/h).[47] Later that day Josephine transitioned into an extratropical cyclone and suddenly intensified to winds of 60 mph (95 km/h). The extratropical low was quickly absorbed by another larger extratropical system on the afternoon of September 19.[43][48]
