The storm intensified significantly over the next few days, and by August 22, it peaked as a Category 3 hurricane with maximum sustained winds of 125 mph (205 km/h).

In New England, rainfall caused minor street flooding, especially in central Massachusetts and Maine, where 2.09 inches (53 mm) of precipitation fell in the city of Portland.

Of the 173–192 fatalities in Canada, most of them occurred due to damaged or missing ships, with two boats losing their entire crew.

Crop damage from the hurricane was severe as the storm destroyed about half of the fruit, vegetable, and hay harvest, leaving a loss of $1 million (1927 USD).

The storm's rains and winds caused similar but less severe damage in the provinces of New Brunswick, Prince Edward Island, and Newfoundland.

The cyclone peaked as a Category 3 hurricane with sustained winds of 125 mph (205 km/h) and a minimum pressure of 950 mbar (28 inHg) around 06:00 UTC on August 22.

Around 18:00 UTC on August 24, the hurricane made its closest approach to the United States, passing about 60 mi (100 km) southeast of Nantucket island in Massachusetts.

[3] Based on distribution of rainfall over Nova Scotia, the storm was believed to have made landfall as a tropical cyclone.

The remnants moved quickly east-northeastward, striking Newfoundland and later Iceland, before dissipating near Jan Mayen on August 29.

[3] Shipping ahead of the hurricane received repeated warnings broadcast by both American and Canadian weather officials.

[7] Rainfall from the hurricane contributed to causing the Taunton River to reach its then-highest known crest at some locations, forcing floodgates to be opened.

About a half-dozen locations along the New York, New Haven and Hartford Railroad from Brockton to Middleborough were inundated with between 6 and 10 in (150 and 250 mm) of water, resulting in a difficult passage of trains over the low-lying grades.

Heavy rainfall brought by the hurricane caused landslides and flooding along the Harbourville Mountain which washed out numerous roads.

In Lakeville, flooding washed away a 25-foot (7.6 m) bridge, and fallen trees and other storm debris littered the streets and roads.

[14] Roads were extensively impacted in Digby, Wolfville, Yarmouth, and Annapolis County, which suffered $150,000 in damage to streets alone.

Crop damage from the hurricane was severe as the storm destroyed 50 percent of the fruit, vegetable, and hay harvest, leaving a loss of $1 million.

[12] Wind gusts in Newfoundland as strong as 90 mph (140 km/h) at the Corner Brook subdivision of Curling caused about $500 in damage to circus tents and associated equipment.

Throughout the province, streets, bridges, gardens, and crops, particularly hay and grain, were damaged, while railroad lines were destroyed.

The Joyce Smith was carrying 22 men (mostly from Newfoundland) and it and the Walters were fishing off the coast of Sable Island at the time of the hurricane.

Today, the hurricane is commemorated in a waterfront monument and an exhibit at the Fisheries Museum of the Atlantic in Lunenburg, Nova Scotia.
