Hurricane Alberto began to weaken on August 22 as it accelerated into higher latitudes. It was downgraded to a tropical storm early on August 23. Initially, it was forecast to become extratropical on August 22, but a little burst of colder cloud tops enabled Alberto to remain tropical for a longer time, persisting into August 23, while it moved into a very high latitude of 53˚N. The weakening storm finally became extratropical late on August 23, while accelerating to the north-northeast, passing near Iceland on August 24. Gale-force winds became non-existent, as the centre turned to the east-northeast on August 25. Alberto dissipated about 85 mi (140 km) east of Jan Mayen later that day.
