JOHANNESBURG — Cyclone Kenneth dumped heavy rains in northern Mozambique on Sunday, flooding parts of a provincial capital, prompting evacuations and complicating efforts by rescuers to reach remote areas. The storm has killed at least five people so far, the government said.

Many roads were washed out, and aid officials said they had been able to reach some badly affected areas only by helicopter.

Rains were heaviest in Pemba, the capital of Cabo Delgado Province, which lost power. Rescue teams were evacuating residents, and 4,500 people have sought shelter in refuge centers.
