Tropical Storm Arlene brought blustery conditions to much of eastern Mexico in late June to early July 2011. The first named storm and first tropical cyclone of the 2011 Atlantic hurricane season. 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. Tropical Storm: peak winds of 65 mph (55 knots), lowest pressure 993 mb. June 28 – July 1, 2011. Landfall: June 30 at 65 mph, 21.6°N 97.4°W. Accumulated cyclone energy: 1.9. Wiki link Track: NOAA National Hurricane Center, HURDAT2 best track AL012011 (public domain).
