Tropical storm Amanda killed at least 14 people during its passage through El Salvador and displaced more than 1200 families in four regions of the country and damaging 900 houses.
"We mourn and extend our deepest condolences to each of the families," the head of the Salvadorian government cabinet, Carolina Recinos, said at a media conference.
Fifty-one shelters for more than 1200 families have been set up in the regions of La Libertad, San Salvador, Sonsonate and San Vicente, she added.
Four people are also missing, Interior Minister Mario Duran said.
San Salvador Mayor Ernesto Muyshondt said people had been evacuated in the capital.
Floods and landslides caused by heavy rains early on Sunday damaged 900 homes, most of them in San Salvador, where 50 are reportedly destroyed.
The government, which will have to divide its efforts to tackle this emergency alongside the COVID-19 pandemic, will allow hardware stores to open and operate with 40 per cent capacity for people to buy equipment for repairs.
The government has also lifted the restriction on people's movement based on their identity card number so they can buy medicines without the need to present ID.
The hurricane, having formed on Sunday, is moving over Guatemala towards Mexico, the Mexican National Weather Service reports.
