Tropical Storm Arlene, the first named storm of the 2011 Atlantic hurricane season, brought blustery conditions to much of eastern Mexico in late June to early July 2012. Arlene originated from an Atlantic tropical wave, which crossed the Yucatán Peninsula before emerging over warm waters in the Bay of Campeche. Despite moderate wind shear, the disturbance strengthened and developed a surface circulation, prompting the National Hurricane Center to declare it a tropical storm on June 28. Arlene remained vigorous for most of its existence; the storm peaked in intensity with winds of 65 mph (100 km/h) on June 30, just before making landfall on the coast of Veracruz. Crossing the mountains of eastern Mexico, Arlene weakened to a depression before dissipating early on July 1.
