Tropical Storm Arlene, the first named storm of the Atlantic hurricane season, killed 22 people as it moved across Mexico last week, the emergency management office said.

The storm, packing maximum sustained winds of about 100 kph (62 mph), made landfall Thursday near Cabo Rojo, a town on the east coast of Mexico.

The storm killed 16 men, four women and two people whose gender has not been determined, the emergency management office said.

Ten of the victims, including one in an automobile, perished when they were swept away while trying to cross a river, while six others died in mudslides and five were electrocuted, of whom three touched downed power lines and two were struck by lightning.

Five people died in Hidalgo, five in San Luis Potosi, one in Mexico state, which surrounds the Federal District and forms part of the Mexico City metropolitan area, and one in Puebla, all located in central Mexico.

The storm also killed three people in the eastern state of Veracruz and two in Guerrero, two in Oaxaca and one in Chiapas, located in southern Mexico, as well as two people in the northeastern state of Tamaulipas.

Arlene quickly dissipated as it moved over land, but the storm dumped heavy rains in some areas, prompting officials to declare a state of emergency in 53 cities in Veracruz and two cities in Mexico state, the emergency management office said.

A disaster declaration was also issued in Mexico state, the country's most populous state, due to the damage caused by the storm.

The Atlantic hurricane season started on June 1 and ends on Nov. 30.
