Irene formed on August 4^th west of Cape Verde. Despite poor organization and shearing wind it became a tropical storm on August 7^th. Irene went back and fourth between strengthening and weakening. It became disorganized on the morning of August 10^th and this caused forecasters to declare that the storm dissipated. Later it regrouped and became a category 1 hurricane on August 14^th. On August 16^th it became a category 2 hurricane briefly. It eventually became an extra tropical south east of Cape Race, Newfoundland on August 18^th. Irene never posed a threat to land.
