The tropical depression off the coast of Mexico is targeting the area soaked by Hurricane John By Reuters

MEXICO CITY (Reuters) – A new storm system that made landfall on Mexico’s southern Pacific coast and near Guatemala on Tuesday night is expected to move inland on Wednesday, according to the U.S. National Hurricane Center (NHC ).

The tropical depression, called Eleven-E because it is not yet a named storm, is likely to strengthen to tropical storm strength overnight, threatening further flooding and landslides, the NHC said. The area has recently had devastating rains.

Last week, Hurricane John and its remnants dumped massive amounts of rain over much of Mexico’s southwestern coast, triggering deadly mudslides that left at least 22 dead.

The Miami forecaster said the tropical depression is located about 75 miles (121 km) southeast of the main Mexican port of Salina Cruz in Oaxaca state. The port is home to a major oil refinery operated by the national oil company Pemex.

The company did not immediately respond to a request for comment after its business hours.

The storm system is expected to produce between 4 and 12 inches (10 cm and 30 cm) of rain in several southern Mexican states as well as a portion of western Guatemala, the NHC said.
