(CNN) -- It's a double threat. Hurricanes are barreling through the ocean on both sides of the continental United States. Hurricane Gonzalo on Friday slammed the British territory of Bermuda in the North Atlantic Ocean. Hurricane Ana is heading for the Hawaiian Islands and could cause trouble over the weekend.
Hurricane warnings were posted on Bermuda as Gonzalo raged through the region. The powerful Category 3 storm battered the island with wind gusts that topped 115 miles per hour, according to the National Hurricane Center in Miami, as it moved in a northeasterly direction at 16 miles per hour.
