Hurricane Fiona has continued to strengthen in the Atlantic, becoming a powerful Category 4 storm early Wednesday. After becoming the season's first major hurricane on Tuesday, the storm is finally moving away from the Turks and Caicos and the Caribbean islands after pummeling the area with heavy rainfall and life-threatening flash flooding, the National Hurricane Center reports. As of the 5 p.m. Wednesday advisory from the NHC, the storm was moving to the north at 9 mph. Fiona is a Category 4 hurricane with maximum sustained wind speeds of 130 mph. While Fiona intensified quickly overnight Monday it did not technically "rapidly intensify." This classification is given to a tropical cyclone (tropical depression, tropical storm or hurricane) when the winds increase 35 mph or more in a 24-hour period.
