8 p.m. UPDATE: The remnants of Tropical Storm Kirk are likely to redevelop into a tropical cyclone during the next day or two before it moves into an area of highly unfavorable upper-level winds as it approaches the Caribbean, according to the latest Tropical Weather Outlook from the National Hurricane Center in Miami.
At 8 p.m., the remnants were about 750 miles east of the Windward Islands and moving quickly westward at 20-25 mph. Chance of tropical formation in the next 48 hours was 70 percent.
Meanwhile, off the coast of North Carolina, a low pressure area still has a 50 percent chance of becoming a tropical system. An Air Force Reserve Hurricane Hunter aircraft reported that the circulation has become better defined but the associated showers and thunderstorms remain disorganized.
11 p.m. UPDATE: Tropical Storm Kirk’s top sustained winds decreased to near 35 mph as it accelerated westward across the Atlantic, according to the latest National Hurricane Center advisory. It’s now a tropical depression.
Kirk is about 835 miles west-southwest of the southernmost Cabo Verde Islands and moving rapidly around 25 mph.
Little change in the maximum winds is forecast during the next several days. But forecasters said Kirk could degenerate into a trough of low pressure as it moves quickly across the tropical central Atlantic over the next several days.
5 p.m. UPDATE: Tropical Storm Kirk continues on its rapid westward trek across the tropical Atlantic, speeding due west at 23 mph, according to the latest National Hurricane Center advisory.
Kirk is about 645 miles southwest of the southernmost Cabo Verde Islands with maximum sustained winds near 40 mph. Some strengthening is forecast during the next day or two.
However, Kirk could encounter shear that could weaken the storm over the Caribbean.
Meanwhile, newly named Subtropical Storm Leslie is crawling toward the west in the middle of the Atlantic. Maximum sustained winds are near 40 mph, but Leslie is forecast to dissipate in a few days.
11 a.m. UPDATE: Tropical Storm Kirk continues its westward trek, and is now moving west at 21 mph. It is 545 miles southwest of the Cape Verde Islands and still has maximum sustained winds of 40 mph, according to the National Hurricane Center. Kirk’s forecast of continued westward movement and strengthening early in the week hasn’t changed.
Meanwhile, a new storm, Leslie, has formed. A subtropical storm, Leslie has maximum sustained winds of 40 mph, and is out in the middle of the Atlantic on the same latitude as South Carolina. Leslie is only moving west at about 3 mph and isn’t expected to move very far in the next two days, forecasters say.
NHC forecasters predict Leslie will likely be absorbed by a larger low-pressure system by mid-week.
Finally, Tropical Depression 11 is no more. The remnants of the depression were expected to weaken further in the next day or so. They have maximum sustained winds of 25 mph and are about 350 miles east-northeast of the Windward Islands.

Forecasters say Kirk will begin moving more quickly across the ocean as of Tuesday and is expected to strengthen in the next two days. However, they add it may begin weakening in the middle of the week.
Meanwhile, Tropical Depression 11, what forecasters are calling a “poorly organized” storm, is likely to dissipate by this evening. It’s 415 miles east-northeast of the Windward Islands and had maximum sustained winds of 30 mph.
11 p.m. UPDATE: Kirk is about 425 miles south-southwest of the southernmost Cabo Verde Islands and moving west-northwest about around 16 mph, according to the National Hurricane Center advisory. Top sustained winds were still 40 mph.
A faster westward motion across the deep tropical Atlantic Ocean is expected Sunday through Tuesday. Some strengthening is forecast through Sunday night, with little change in intensity expected on Monday and Tuesday.
Meanwhile, poorly organized Tropical Depression 11 is creeping northwestward about 440 miles east of the Windward Islands with sustained winds of 30 mph.
The depression is forecast to dissipate on Sunday or early Monday.
5pm UPDATE: (Eliot Kleinberg)
Tropical Storm Kirk, which formed overnight, continued Saturday to cross the Atlantic Ocean, steering toward a possible collision with the islands of the eastern Caribbean by the end of next week, according to a 5 p.m. National Hurricane Center advisory.
At 5 p.m. Saturday, Kirk was about 430 miles south of the Cabo Verde Islands and was moving west-northwest at 15 mph, up slightly from its earlier 14 mph pace. Top sustained winds were 40 mph.
” A faster westward motion across the deep tropical Atlantic Ocean is expected Sunday through Tuesday,” the advisory said.

Tropical Storm Kirk has formed out in the eastern Atlantic, and is expected to move quickly across the ocean and possibly threaten islands as early as Thursday, the National Hurricane Center said Saturday in an 11 a.m. advisory.
At 11 a.m., Kirk was far south of the Cabo Verde Islands. Top winds were 40 mph, just 1 mph over the minimum to be a tropical storm. It was moving west near 14 mph and was expected to speed up from Sunday through Tuesday.
“Some strengthening is forecast through Sunday, with little change in intensity forecast on Monday and Tuesday,” the advisory said.
