(CNN) -- Once a tropical storm, Colin was downgraded Sunday to a tropical depression before dissipating entirely, the National Hurricane Center said.
As of 5 p.m. ET, the remnants of Colin were located about 60 miles (100 kilometers) northwest of Bermuda, forecasters said. It was moving north at about 12 mph (19 kph) with maximum sustained winds of near 30 mph (45 kph).
A tropical storm watch for Bermuda was discontinued, the hurricane center said.
However, tropical storm-force wind gusts were possible overnight for Bermuda, forecasters said, and Colin was expected to produce some coastal flooding and large waves along Bermuda's south-facing beaches. The system is expected to dump between one and two inches of rain on Bermuda.
Meanwhile, an area of low pressure in the eastern North Atlantic is showing signs of organization and could become Tropical Depression Five or Tropical Storm Danielle, according to CNN meteorologist Sean Morris. The National Hurricane Center has given the system a 70 percent, or high, chance of becoming a tropical cyclone in the next 48 hours.
Computer models show the system turning toward the north and then northeast, away from the United States and Bermuda, and losing tropical characteristics before it affects land.
