The African nation's emergency officials said 30,000 people have been evacuated from the areas the storm would likely hit.
Forecasters say Kenneth could bring waves as high as five meters and some 600 millimeters of rainfall.
Kenneth descends on Mozambique just weeks after the the country was hit by Cyclone Idai which the U.N. labeled as "one of the deadliest storms on record in the southern hemisphere."
Officials have warned that Cyclone Kenneth could be even stronger than Idai as it targets an area not used to such storms.
This is the first time on record that Mozambique has been hit by two cyclones in one season, a U.N. spokesman said.
Before Mozambique, Kenneth swept over the island nation of Comoros, killing three people.
