The Mexican oil export facility at Pajaritos in eastern Veracruz state reopened to shipping traffic early on Thursday and the nation's three other oil ports were operating normally, said port officials.
Pajaritos, part of the Coatzacoalcos complex, reopened at 6 a.m. (1200 GMT) as weather conditions improved, said an official at the captain's office. Winds were around 3 miles per hour (5 km per hour) and waves were between two and three feet, he said.
The Gulf ports of Dos Bocas in southeastern Tabasco state and Cayo Arcas in nearby Campeche state were also open to shipping, said officials at the captain's office in each port.
Salina Cruz on the Pacific coast was operating normally, said port officials.
