Kirk passed narrowly north of Barbados, where tropical storm-force winds cut power to multiple neighborhoods and caused property damage at the official residence of the Governor-General.

In Saint Vincent and the Grenadines, rough seas caused coastal flooding and led to the presumed deaths of two fishermen after they ventured out during the storm.

On Saint Lucia, strong winds destroyed two buildings; additional structures, including schools and the anemometer at the Hewanorra International Airport, sustained damage.

After two days of sporadic convective development, it acquired sufficient organization to be declared a tropical depression by the National Hurricane Center (NHC) around 06:00 UTC on September 22 to the south of Cabo Verde.

Thereafter, the cyclone's presentation morphed into a comma-shaped appearance, with the center at times partially exposed on the western edge of this convection due to increasing westerly wind shear.

[4] Kirk temporarily moved west-northwest, passing just north of Barbados, before banking west-southwest under the dominant steering regime of a ridge in the western Atlantic.

By 00:00 UTC on September 29, after a reconnaissance aircraft was unable to locate a well-defined and closed center, the NHC downgraded Kirk to a tropical wave again while it was positioned a few hundred miles south of the United States Virgin Islands.

[1] Rainfall in excess of 10 in (250 mm) caused extensive flooding of streets and homes, peaking on the night of September 27–28 on the back end of the storm system.

[18] About 40 of the 110 buses owned by Barbados Transport Board were removed from service to allow for repairs of water-related damage incurred while driving through flooded streets.

[21] A stretch of beach on the south coast was closed until the evening of October 1 so the sluice gate that regulates the Graeme Hall Swamp could be opened to release excess rainwater.

Coastal flooding due to high surf forced three families to evacuate their homes in New Sandy Bay Village and seek shelter in a public school.

[34] This donation marked the beginning of the Banana Productivity Improvement Project, a joint program between the ICDF and the Saint Lucia government to support and educate farmers.

[39] During his four-day tour of the French West Indies, President of France Emmanuel Macron canceled a planned visit to Fort-de-France in response to the storm.

[41] After Kirk dissipated, its remnants interacted with a trough of low pressure to produce showers and thunderstorms across Jamaica that prompted the dissemination of flash flood watches.
