Sub-Tropical storm Leslie is moving out over the Atlantic. Unfavorable upper-level winds and dry air are expected to limit development tonight and Sunday, but conditions could become more conducive for some development of this system on Monday or Tuesday while it moves westward and west-northwestward over the southwestern Atlantic Ocean. It may impact the Windward Islands as soon as Wednesday.
Winds are sustained at 40 miles per hour and is moving west at 14 miles per hour. After that time, with the development of the new low to the north, Leslie will likely move east until it becomes absorbed.
Kirk reached tropical storm-strength Saturday and is cruising west at about 18 miles per hour, the National Hurricane Center said Sunday morning. Isaac then weakened to a tropical storm as it passed through the Lesser Antilles, though it did produce heavy rainfall.
At 5 a.m., the center of the storm was located near 9.1 degrees north, 28.0 degrees west or about 465 miles south-southwest of the Cabo Verde Islands.
One possible storm down and two to go, with another maybe in the wings.
No coastal warnings or watches are in effect for the storm. A slight decrease in forward motion is expected by mid-week.
The second wave is located about 1000 miles west-southwest of the Azores. Some strengthening is expected in coming days, but forecasters say Kirk is likely to begin weakening later in the week. "In fact, after becoming extratropical, the models show Leslie merging with another frontal low to its north, leading to the formation of a powerful slow-moving non-tropical low with gale- or storm-force winds over the central Atlantic later this week", reads a discussion of the storm.
