Cuba prepared to evacuate people along the island’s southern region on Sunday amid fears that Tropical Storm Elsa could unleash heavy flooding after battering several Caribbean islands, killing at least three people.

The government opened shelters and moved to protect sugarcane and cocoa crops ahead of the storm, whose next target was Florida, where Gov. Ron DeSantis declared a state of emergency in 15 counties, including in Miami-Dade County where the high-rise condominium building collapsed last week.

Elsa was located about 175 miles (280 kilometers) east-southeast of Montego Bay, Jamaica, and was speeding west-northwest at 17 mph (28 kph). It had maximum sustained winds of 65 mph (100 kph), according to the National Hurricane Center in Miami.

The storm killed one person in St. Lucia, according to the Caribbean Disaster Emergency Management Agency. Meanwhile, a 15-year-old boy and a 75-year-old woman died Saturday in separate events in the Dominican Republic after walls collapsed on them, according to a statement from the Emergency Operations Center.

Elsa was a Category 1 hurricane up until Saturday morning, causing widespread damage in several eastern Caribbean islands on Friday as the first hurricane of the Atlantic season. Among the hardest hit was Barbados, where more than 1,100 people reported damaged houses, including 62 homes that completely collapsed as the government promised to find and fund temporary housing to avoid clustering people in shelters amid the pandemic.

Downed trees also were reported in Haiti, which is especially vulnerable to floods and landslides because of widespread erosion and deforestation.

A tropical storm warning was in effect for Jamaica and from the Haitian capital of Port-au-Prince to the southern border with the Dominican Republic. A hurricane watch was issued for the Cuban provinces of Camaguey, Granma, Guantanamo, Holguin, Las Tunas, and Santiago de Cuba. Some of those provinces have reported a high number of COVID-19 infections, raising concerns that the storm could force large groups of people to seek shelter together.

Elsa is the earliest fifth-named storm on record and also broke the record as the tropic’s fastest-moving hurricane, clocking in at 31 mph on Saturday morning, according to Brian McNoldy, a hurricane researcher at the University of Miami.
