The storm is infamous for striking just 20 days prior to the devastating 1867 Virgin Islands earthquake and tsunami in the same region.

In a 2014 analysis, climate historian Michael Chenoweth suggested that the storm reached Category 4 intensity. In total, it caused at least 811 deaths in Saint Thomas (Danish West Indies) and Captaincy General of Puerto Rico and around $1 million (1867 USD) in damage.

Meteorological history

On October 27, the storm developed northeast of the Lesser Antilles unusually late into the season, in which the mail steamer Principe Alfonso skillfully avoided the storm. This tropical storm continued westward before intensifying to a hurricane the next day. It then reached category 3 status on October 29, before striking Sombrero, Anguilla near or at peak intensity. After 8 am local, a barometric pressure of 28.65 inches of mercury (97.0 kPa) accompanied by a half-hour calm occurred. The wind then shifted to a violent easterly until 11 am and then diminished through 1 pm. The hurricane reached its peak intensity of 125 miles per hour (201 km/h) at 1200 UTC near the island.

From 1:30 pm to 2:00 pm local, the eye passed over Sankt Thomas, Danish West Indies.

The hurricane made landfall on Puerto Rico late during the day on October 29th; less than three days from November. Despite its small size, it ranks among the most intense hurricanes recorded on the island. It passed near the city of Fajardo between 5 pm and 6 pm local, and later passed near Caguas. People sensed tremors in the towns of Humacao, Luquillo, and Peñuelas. The storm affected every town on the island of Puerto Rico. It then struck the island of Hispaniola as a hurricane, and then dissipated over the high mountains on October 30th.
