El Salvador President Nayib Bukele declared a 15-day state of emergency to cope with the effects of the storm, which he estimated to have caused $200 million in damage, but which weakened later in the day as it moved into Guatemala.

Amanda, the first named storm of the season in the Pacific, unleashed torrents of floodwater that tossed vehicles around like toys and damaged about 200 homes, the head of the Civil Protection Service William Hernandez said.

The fatalities were all recorded in El Salvador, Interior Minister Mario Duran said, warning that the death toll could rise.

One person is still missing, senior government official Carolina Recinos added.

"We are experiencing an unprecedented situation: one top-level emergency on top of another serious one," San Salvador mayor Ernesto Muyshondt said, referring to the coronavirus pandemic.

He added that half of those killed died in the capital, and that 4,200 people had sought refuge in government-run shelters after losing their homes or being forced to leave because they were in high-risk areas.

In some flooded areas, soldiers worked alongside emergency personnel to rescue people.

"We lost everything, we've been left with nowhere to live," said Isidro Gomez, a resident of hard-hit southeastern San Salvador, after a nearby river overflowed and destroyed his home.

Another victim, Mariano Ramos, said that at dawn residents of his San Salvador neighborhood were slammed by an avalanche of mud and water. An elderly man died in the area, officials said.

El Salvador's environment ministry warned residents of the "high probability" of multiple landslides that could damage buildings and injure or kill people.

Nearly 90 percent of El Salvador's 6.6 million people are considered vulnerable to flooding and landslides due to its geography.

In neighboring Guatemala, officials said roads had been blocked by at least five landslides and some flooding was reported, but no evacuations were underway.
