month. However, the month of November was considered to be very active, with three storms forming during that month. The season's activity was reflected with an accumulated cyclone energy (ACE) rating of 149, which is classified as "above normal". 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. Its only calculated for full advisories on tropical systems at or exceeding 39 mph (63 km/h), which is the threshold for tropical storm intensity. Systems Tropical Depression One A decaying cold front entered into Gulf of Mexico, and developed a low-pressure area of July 17. Later that day, the low-pressure area developed into Tropical Depression One almost halfway between Louisiana and the Yucatán Peninsula. The depression moved northwestward, and minimal intensification occurred, as it approached the Gulf Coast of the United States. The depression made landfall in Texas near the Galveston area, and dissipated by July 21. Minimal impact was recorded from the depression, and light rainfall was reported in Texas and western Louisiana, peaking at in Refugio, Texas. Hurricane Allen A tropical wave emerged off the west coast of Africa on July 30 and quickly developed into Tropical Depression Two about two days later. By August 2, the depression had strengthened and was upgraded to Tropical Storm Allen. The storm steadily intensified and became a hurricane on August 3. Thereafter, Allen rapidly deepened, and was a major hurricane only 24 hours later. While it was becoming a Category 3 hurricane, and a Category 4 hurricane, shortly after, Allen passed through the Windward Islands. Upon entering the Caribbean Sea, Allen continued to strengthen and became a Category 5 hurricane on August 5, while about halfway between Puerto Rico and Venezuela. Allen briefly curved northwestward and approached the Tiburon Peninsula of Haiti. Shortly thereafter, Allen weakened significantly on August 6, but was still a Category 4 when it bypassed Jamaica. While paralleling the south coast of Cuba, Allen re-strengthened into a Category 5 hurricane. Later that day, the storm attained its peak intensity with winds of 190 mph (305 km/h) and a minimum barometric pressure of . Immediately following peak intensity, Allen entered the Gulf of Mexico and weakened back to a Category 4 hurricane on August 8. On the day next, Allen re-intensified into a
