Hurricane Barbara was the easternmost landfalling Pacific hurricane on record. As the first hurricane of the 2013 Pacific hurricane season, Barbara developed from a low-pressure area while located southeast of Mexico on May 28. It headed slowly north-northeastward and strengthened into a tropical storm early on the following day. After recurving to the northeast, Barbara intensified into a Category 1 hurricane on May 29 and made landfall in Chiapas at peak intensity with winds of 80 mph (130 km/h) and a barometric pressure estimated at 983 mbar (hPa; 29.03 inHg). When the hurricane made landfall, it was the second earliest landfalling hurricane in the basin since reliable records began in 1966. Barbara then moved across the Isthmus of Tehuantepec and dissipated within the mountainous terrain of Sierra Madre de Chiapas on May 30.
