There are still no watches and warnings in effect and it's too soon to know if it will threaten land. A forecast map predicts that the storm will take a turn to the north in the middle of the week, but it's difficult to predict a storm's path days in advance.On Sunday night, the storm's center was about 385 miles (620 km) northeast of the Northern Leeward Islands and moving northwest at 13 mph (20 kph). It had sustained maximum winds of 105 mph (165 kph). Forecasters expect Katia to strengthen further and said it could be a major hurricane by Monday. RELATED: 6abc.com Hurricane Tracker
