Hurricane Oscar made landfall Sunday evening on the northern coast of east Cuba, according to the National Hurricane Center.

The hurricane made landfall at 5:50 p.m. ET in the Cuban province of Guantanamo, near the city of Baracoa, the hurricane center said.

The storm has weakened, and as of the center’s 8 p.m. update, it had winds of 75 mph with higher gusts. At landfall, Oscar was packing maximum sustained winds near 80 mph.

The storm was “bringing hurricane conditions, heavy rainfall, and storm surge to portions of eastern Cuba,” the center said.

Oscar, which the National Hurricane Center had characterized as “compact but powerful,” formed off the coast of the Bahamas Saturday, prompting a hurricane warning for the north coast of Cuba’s Holguin and Guantanamo provinces, all the way to the easternmost tip of the island, Punta de Maisi.

The Category 1 storm was moving west-southwest at 6 mph, according to the hurricane center update.

“Weakening is expected as Oscar interacts with the mountainous terrain of eastern Cuba, but Oscar could still be a tropical storm when it moves north of Cuba late Monday and then moves across the central Bahamas on Tuesday,” the NHC said in the 8 p.m. ET update.

Cuba was already dealing with dayslong outages following four major grid failures since Friday.

The country was bracing for impact with storm warnings and watches. In addition to the hurricane warnings, the north coast of the Cuban province of Las Tunas was under both a hurricane watch and tropical storm warning.

A tropical storm warning was in effect for the southeastern Bahamas as well as the south coast of Guantanamo, and a tropical storm watch was in effect for the north coast of the province of Camaguey as well as the central Bahamas.

Rainfall in eastern Cuba is expected to reach 6 to 12 inches with up to 18 inches of rainfall in some places through Wednesday, the center said. The southeastern Bahamas can get anywhere from 3 to 8 inches of rain, and Turks and Caicos may get 2 to 4 inches of rain through Wednesday morning.

Around 1 to 3 feet of storm surge can also be expected along Cuba’s north shore, which will be accompanied by “large and destructive waves” near the coast.
