Hurricane Ike strengthened rapidly into an fiercely dangerous Category 4 hurricane in the open Atlantic on Wednesday and Tropical Storm Hanna intensified to a lesser degree as it swirled over the Bahamas toward the southeast US Coast.
Ike posed no immediate threat to land but strengthened explosively, growing in the space of a few hours from a tropical storm to an intense Category 4 hurricane on the five-step Saffir-Simpson intensity scale.
