MIAMI, Florida (CNN) -- Hurricane Fred quickly strengthened into a Category 2 storm early Wednesday, after initially reaching hurricane status six hours earlier, the National Hurricane Center reported.
Hurricane Fred is a Category 1 storm in the Atlantic, but it's not expected to make landfall.
"Some additional strengthening is forecast and Fred could become a major hurricane later today," forecasters said. "Weakening is expected to begin on Thursday."
Fred is the second hurricane of the Atlantic season, which runs through November 30.

Fred was moving toward the west-northwest near 13 mph (20 km/hr) and was expected to turn toward the northwest and then the north-northwest over the next few days as its forward speed decreases.
A National Hurricane Center forecast map shows Fred becoming a tropical depression on Sunday.
In the Pacific, Tropical Storm Linda churned through open waters.
At 2 a.m. PT (5 a.m. ET), Linda was located about 1,300 miles (2,095 km) west-southwest of the southern tip of Baja California and was more than 1,700 miles (2,800 km) east of Hawaii.
The storm had maximum sustained winds near 65 mph (100 km/hr) and was meandering to the north-northwest at about 2 mph (4 km/hr).
"Some additional strengthening is possible tonight and Wednesday," the hurricane center said. Linda is forecast to weaken on Thursday.
Neither storm was expected to make landfall before dissipating.
