1854 Atlantic hurricane season
The 1853 Atlantic hurricane season featured five known tropical cyclones, three of which made landfall in the United States. At one time, another was believed to have existed near Galveston, Texas in September, but HURDAT – the official Atlantic hurricane database – now excludes this system. The first system, Hurricane One, was initially observed on June 25. The final storm, Hurricane Five, was last observed on October 22. These dates fall within the period with the most tropical cyclone activity in the Atlantic. No tropical cyclones during this season existed simultaneously. One tropical cyclone has a single known point in its track due to a sparsity of data.
Of the season's five tropical cyclones, three reached hurricane status. Furthermore, one of those strengthened into a major hurricane, which is Category 3 or higher on the modern-day Saffir–Simpson hurricane wind scale. The strongest cyclone of the season, the third hurricane, peaked at Category 3 strength with 125 mph (205 km/h) winds. After making landfall near the Georgia-South Carolina border, the storm caused 26 fatalities and extensive damage in the area. Hurricane Four caused four deaths and approximately $20,000 (1854 USD) in damage after striking the coast of Texas. Hurricane One also caused moderate damage in Texas.
The season's activity was reflected with a low accumulated cyclone energy (ACE) rating of 31. ACE is, broadly speaking, a measure of the power of the hurricane multiplied by the length of time it existed, so storms that last a long time, as well as particularly strong hurricanes, have high ACEs. ACE is only calculated for full advisories on tropical systems at or exceeding 34 knots (39 mph, 63 km/h) or tropical storm strength.
