In early June, a low pressure system entered the Caribbean Sea. The low remained disorganized with only isolated convection, mostly in the eastern quadrant. Convection began to wrap into the center as the storm curved northward into the Gulf of Mexico on June 3. After the low passed over the Yucatán Peninsula on June 5, the National Hurricane Center upgraded it to Tropical Depression Three and tropical storm warnings were issued for the Big Bend of Florida. Later that day, the depression intensified into Tropical Storm Colin, just after tropical storm watches were put in place for eastern Florida and Georgia. The formation into a tropical storm marked the earliest formation on record of the third named storm within the Atlantic basin, exceeding the previous record set in 1887 by seven days.
