In an 11 a.m. update on Saturday, the National Hurricane Center said Kirk was moving west at 14 miles per hour with maximum sustained winds near 40 miles per hour.
Meanwhile, Tropical Depression 11, what forecasters are calling a "poorly organized" storm, is likely to dissipate by this evening. National Hurricane Center advisory, Kirk's sustained winds measured 35 mph and extended 70 miles north of the storm's center.
As of 5 a.m., Kirk was 465 miles south-southwest of the Cape Verde Islands, heading west at 18 mph. Strong upper-level winds are expected to diminish by Sunday or Monday, which could allow for some slow development of this system while it moves westward and then northwestward over the southwestern Atlantic Ocean.
The National Hurricane Center thinks Leslie could merge with another subtropical low that could form nearby this week.
NHC forecasters predict Leslie will likely be absorbed by a larger low-pressure system by mid-week.

When manure pits overflow, there is a risk that water supplies will be contaminated with bacteria like salmonella and e. coli. Thousands of homes are still underwater in the Carolinas and thousands of families have had to be rescued from the floods.
Some intensification is possible this weekend, but vertical wind shear may increase next week possibly limiting additional strengthening.
The system is expected to be close to the Lesser Antilles by Thursday. It may strengthen some in the next two days, but some dry air will prevent too much strengthening.
"Low- to mid-level ridging over the eastern Atlantic is expected to cause Kirk to move even faster toward the west during the next couple of days, reaching speeds of at least 22 kt in 24-36 hours".
While some storms are just getting started, Tropical Depression 11 near the Windward Islands dissipated Sunday afternoon. This low, called Invest 98 for now, has been fighting a lot of wind shear, so development chances only sit at 30 percent.
