The 2011 Atlantic hurricane season was one of the most active Atlantic hurricane seasons since 1851. The season started on June 1, 2011 and it ended on November 30, 2011.[1] This season has been "above-average". This means that there has been a lot of tropical cyclones that have developed in the Atlantic basin. The season started when Tropical Storm Arlene formed on June 29. It formed in the Gulf of Mexico. It then made landfall on Veracruz. The storm killed 25 people. The amount of damage was $223 million (2011 USD). After Arlene dissipated, a lot of tropical storms began developing. Most of them developed from a frontal boundary. Which makes this season the first time to have the first eight named storms to have not reached hurricane status.[2]
The record ended when Hurricane Irene formed in late August. Irene also became the first major hurricane (being a category three or higher on the Saffir–Simpson Hurricane Scale). After Irene dissipated, Hurricane Katia became the second major hurricane of the season. With seventeen tropical storms, only four became hurricanes. The following hurricane was Hurricane Rina. Between September 7-9, there were three tropical cyclones active, which were Katia, Maria and Nate. This information made the Climate Prediction Center issue a La Niña Advisory.[3]
