National Hurricane Center tracking Tropical Storm Don. New tropical wave appears on map
Tropical Storm Don picked up some speed and power, but it's still not expected to impact land, according to the latest advisory from the National Hurricane Center.
As Don turns more toward the west over the next couple of days, it should move over warmer waters, allowing some gradual strengthening.
Also in the Atlantic basin are three tropical waves, including one in the eastern Atlantic with a 20 percent chance of developing over the next seven days.
In the Pacific, Calvin has become a post-tropical cyclone as it pulls away from Hawaii. Maximum sustained winds are 40 mph.
Tropical storm warnings for Calvin have been discontinued.
