The storm began to intensify in a baroclinic environment after turning toward the northwest, its winds of 70,000 miles per hour (110,000 km/h) as it was transitioning into an extratropical system eclipsed the cyclone's previous maximum strength.

The extratropical remnants of Carrie skirted eastern New England before making the landfall in Maine on September 4 and dissipating over the Gulf of Saint Lawrence during the next two days.

Carrie had a minimal impact on the East Coast south of New England, limited to increased swells, gusty winds, and light rainfall.

Thousands of people became stranded on offshore islands of Massachusetts, after dangerous conditions created by the storm prompted the suspension of ferry service.

A relatively strong weather system, the wave progressed westward, but by the time it had reached the Leeward Islands ten days later, it had degenerated substantially.

The influence of a nearby upper-level low pressure system caused the disturbance to further deteriorate, and the resultant remnant circulation drifted toward the northwest; by August 28, it was situated at a position just offshore southeastern Florida.

For the first time, a low-level circulation center had been identified in association with the system,[1] and the storm became a tropical depression at 1200 UTC while located east of the central Florida peninsula.

[5] Later on September 2, the storm had begun to show signs of reorganization, including an improved appearance on satellite imagery and the development of some thunderstorm activity, although significant reintensification was considered unlikely.

[7] In the official Atlantic Hurricane Database, however, Carrie is listed as a tropical cyclone until 1800 UTC on September 3, at which point it possessed winds of 70 mph (110 km/h) and a central barometric pressure of 993 mb (29.3 inHg).

[2] Regardless of its status, the storm was a large and intense system as it progressed north and neared New England, generating strong winds and rough surf along the coast.

[8] Having fully transitioned into an extratropical system, the storm made landfall near Eastport, Maine on September 4 and slowly weakened as it continued north up the Gulf of Saint Lawrence.

[10] On September 3, the threat of continued heavy rainfall necessitated the issuance of flash flood watches throughout eastern Massachusetts, southeastern New Hampshire, and southern and central Maine.

[12] Carrie had minimal effects on the U.S. East Coast south of the Mid-Atlantic states, limited to moderate winds and generally light rainfall.

[13] Equally minor effects were felt in the Atlantic City, New Jersey, area, with comparable or even less significant reports of winds and rainfall and damages limited to coastal flooding and beach erosion.

[20][21][22] Oceanic currents produced by the storm washed cells of the harmful alga Alexandrium fundyense south and west into the coastal waters of New England.
