Tropical Cyclone Hidaya had triggered heavy rains and winds as it rolled towards Tanzania and neighboring Kenya, countries already battered by torrential downpours and floods that have left more than 400 people dead across East Africa in recent weeks.
In a statement published early Sunday on X, the Tanzania Meteorological Authority said that Hidaya had "completely lost its strength" after making landfall on Mafia Island in the Indian Ocean on Saturday.
"Therefore, there is no further threat of Tropical Cyclone 'Hidaya' in our country," it added.
Beaches on the Indian Ocean coast were deserted, shops were closed and marine transport suspended in the Zanzibar archipelago as the country braced for the cyclone.
As it approached, the storm had caused much heavier rainfall than normal in coastal areas but no casualties or damage were reported.
At least 155 people have died in Tanzania as heavier-than-usual torrential rains linked to the El Nino weather pattern triggered floods and landslides last month.
In neighboring Kenya, which had also taken precautions for the cyclone, a total of 210 people have been killed in flood-related incidents.
