The latest forecast says Kirk was moving west near 14 miles per hour and a westward to west- northwestward motion at a similar forward speed is expected to continue through tonight.
Kirk does not pose a threat to the US over the next eight days. But forecasters are also keeping an eye on an area of disturbed weather between the Bahamas and Bermuda that could move toward the USA east coast later this week.
Kirk is expected to move west toward the Caribbean Ocean over the next several days.
"Kirk is moving through an environment of warm water and within an area of relatively low shear", AccuWeather Expert Senior Meteorologist Dan Kottlowski said.
Tropical Depression 11 formed overnight about 500 miles east of the Windward Islands and as of 8 a.m. Saturday, it was moving due west at about 5 mph. "The biggest limiting factors for intensification would be the cyclone's fast motion and possible entrainment of dry air". 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 two "outermost" waves will take closer to five days to develop, but the middle wave (Invest 90) has a 70% chance of developing those tropical or subtropical features within the next 48 hours, however, current projections show it simply meandering in the north-central Atlantic and not making progress toward land.
That system is now producing limited showers and thunderstorms, but could see some development.
Tropical Storm Kirk is located 450 miles south of the southernmost Cabo Verde Islands.
This system has a low chance of development. On Sept. 10, Isaac achieved minimal hurricane status as top winds reached 75 miles per hour.
