The 1905 Atlantic hurricane season featured five known tropical cyclones, two of which made landfall in the United States. The first system was initially observed near the Windward Islands on September 6. The last system to dissipate, the fourth storm, transitioned into an extratropical cyclone on October 11, while located well southeast of Newfoundland. These dates fall within the period with the most tropical cyclone activity in the Atlantic. Between October 5 and October 10, the fourth and fifth system existed simultaneously. Of the season's five tropical cyclones, only one reached hurricane status, the fewest since 1890. Furthermore, that storm strengthened into a major hurricane, which is Category 3 or higher on the modern-day Saffir–Simpson hurricane wind scale. This storm, which was the fourth and strongest hurricane of the season, peaked at Category 3 strength with winds. It was also attributed to at least six fatalities after sending a rogue wave across the steerage of the steamer Campania. The first storm also resulted in two deaths after a schooner wrecked in Barbados. The season's activity was reflected with an accumulated cyclone energy (ACE) rating of 28, the lowest value since 1864. ACE is a metric used to express the energy used by a tropical cyclone during its lifetime. Therefore, a storm with a longer duration will have high values of ACE. It is only calculated at six-hour increments in which specific tropical and subtropical systems are either at or above sustained wind speeds of 39 mph (63 km/h), which is the threshold for tropical storm intensity. Thus, tropical depressions are not included here. Timeline Systems Tropical Storm One The first storm of the season, already at tropical storm intensity, was identified on September 6 to the east of Grenada. A small storm, it quickly passed through the southern Lesser Antilles early on September 7. The next day, the storm weakened to a tropical depression before dissipating as a shallow but large system. A schooner sailing from Bridgetown to Suriname encountered heavy seas just a day out of port and turned back. It was thrown onto the pierhead and wrecked. The captain and a crewman were swept overboard and drowned. Tropical Storm Two HURDAT indicates that a tropical storm originated to the northeast of the Windward Islands on September 11. Steadily tracking towards the west-northwest, the storm gradually intensified, reaching its peak intensity with winds estimated at on September 13. After
