- Tropical Storm Kirk is more than 2,000 miles east of the Lesser Antilles.
- Kirk will face a strong wind shear in the Caribbean this weekend.
- As a result, Kirk may be torn as the Lesser Antilles approach.
- Another disturbance could bring downpours in the areas affected by Florence Tuesday or Wednesday.
Tropical storm Kirk may become stronger over the next few days over the eastern Atlantic, but it is expected to weaken as it reaches the Lesser Antilles later this week.
Tropical Storm Kirk, the 11th storm of the 2018 hurricane season, developed on Saturday morning about 450 miles south of the Cabo Verde Islands.
Kirk moves fairly quickly west and will continue to do so midweek. Meanwhile, Kirk can gain a little bit of intensity.
Current state and forecast of the storm (The red box indicates where the center of the system is supposed to follow, impacts may occur well off the road.)
As Kirk gets closer to the Lesser Antilles later this week, he should encounter a rather formidable wind shear wall – changing the wind speed and / or direction with height.
Current satellite and wind shear (The cloud areas are indicated in white, the areas of strong wind shear, the difference in wind speed and direction with height are indicated in purple, and the high wind shear is hostile to mature and tropical cyclones. to those who are trying to grow.)
This strong wind shear should tear Kirk, perhaps to the point of degrading him into a tropical wave by the time he reaches the Windward Islands later on Thursday or Friday.
For the moment, interests in the Lesser Antilles should continue to follow Kirk's progress.
Elsewhere in the Atlantic Basin
Several hundred kilometers east of the Lesser Antilles, eleven tropical depressions is fighting against the aforementioned Caribbean wind shear and should soon dissipate.
The National Hurricane Center (NHC) is also monitoring some other disturbances in the Atlantic for possible development.
A low pressure zone located about 300 miles south-southwest of Bermuda, named Invest 98L by the National Hurricane Center, has had little chance of developing over the next five days.

Although this disturbance is expected to migrate from west to northwest to the Carolinas coast by mid-week, strong winds and / or dry air at high altitudes should minimize all development.
The main impact of this system could be a slight increase in downpours in eastern North Carolina, perhaps Virginia Tidewater, Tuesday to Wednesday morning, before the system slips into the water. 39 North Atlantic Ocean. No heavy rain is expected from this system.

Another system in the central Atlantic between Bermuda and the Azores may turn into a tropical or subtropical storm. It is not expected that it will be an earthly threat as it will continue next week.
The next system that becomes a tropical storm in the Atlantic will receive the name of Leslie.
This activity is not unusual, as the tropical Atlantic can remain busy in late September or early October.

According to the NHC, four named storms develop in the Atlantic basin after mid-September in mid-season, three of which become hurricanes and one becomes a category 3 or stronger hurricane.
