Afterwards, the hurricane slowly moved northwest paralleling the Leeward Islands, remaining steady in intensity for several days.

On October 25, as the system began to accelerate northeast ahead of an approaching trough, Tammy intensified and peaked as a Category 2 hurricane with maximum sustained winds of 110 mph (175 km/h).

Bermuda received minor impacts with wind gusts of 40 mph (65 km/h) as Tammy passed and meandered to the east of the island.

[2] Showers and thunderstorms associated with the disturbance became more concentrated and better organized on October 14,[3] but nearby dry air managed to infiltrate the system, suppressing convection to some degree.

[5] The following afternoon, satellite imagery indicated a well-defined low-level surface circulation, prompting the NHC to designate the system as Tropical Storm Tammy.

[9] Later, Tammy passed to the east-southeast of Guadeloupe,[10] and then at 01:15 UTC on October 22, made landfall on Barbuda at its initial peak intensity with sustained winds of 90 mph (150 km/h).

[12] After weakening to a minimal hurricane while struggling against wind shear for a couple of days, Tammy began to strengthen on October 25 due to increasing upper-level divergence associated with a deep-layer trough.

[13] Later that day, it intensified into a Category 2 hurricane and reached its peak intensity with maximum sustained winds of 110 mph (175 km/h).

[14] Shortly after peaking, Tammy then began to interact with a front to its north, which caused the hurricane to begin its transition to an extratropical cyclone.

Strong vertical wind shear and dry air entrainment quickly stripped the storm of its convection, and it became a remnant low on October 29.

[18] Sint Maarten closed their airport and businesses and the Ministry of Defense requested for soldiers to aid citizens after Tammy passed.

[34] Bermuda was buffeted with wind gusts of 40 mph (65 km/h) late on October 26,[35] resulting in the issuing of a gale warning.
