There’s a new tropical storm in the Atlantic.
Tropical Storm Don, the fourth named storm of 2017, formed on Monday in the central Atlantic, according to the National Hurricane Center.
The hurricane center said the Hurricane Hunter aircraft on Monday found a small but well-defined surface circulation and a small area of tropical-storm-force winds over the eastern semicircle of the circulation. So the tropical wave was given an official title.
At it was getting stronger as of Monday evening. The National Hurricane Center said a reconnaissance aircraft found its winds had risen from 40 to 45 mph.
A tropical storm warning was in effect for the Caribbean island of Grenada, where Don is expected to move near by Tuesday.
A tropical storm watch has also been issued for the islands of Barbados, St. Vincent and the Grenadines and St. Lucia, the hurricane center said.
As of 7 p.m. CDT Monday Tropical Storm Don was located about 405 miles east-southeast of Barbados and is moving west at 17 mph.
On that path Don will move through the Windward Islands late Tuesday.
The hurricane center said Don is moving through a low-shear environment and over warm water, “so some strengthening is possible tonight and Tuesday.”
However, once it enters the eastern Caribbean, unfavorable winds could take their toll, and forecasters said Don could fall apart in 72 hours.
A second tropical system was located to the east of Don in the central Atlantic on Monday evening.
The hurricane center said some gradual development will be possible with this wave while it moves to the west-northwest or northwest over the Atlantic.
It has a 30 percent chance of becoming a tropical depression over the next five days.
The Atlantic hurricane season runs through Nov. 30.
