Early assessments from other areas were grim. Quissanga district reported “extensive damage” to houses, and communication links with Macomia and Muidumbe districts were down, the International Federation of Red Cross and Red Crescent Societies said in a statement.
The aid group cited weekend forecasts of as much as 250 millimeters (9 inches) of torrential rain, about a quarter of the average annual rainfall for the region. The districts of Macomia, Quissanga, Mocimboa da Praia and Mecufi were said to be most at risk.
The largest city in the cyclone-hit region, Pemba, had significant power outages.
While damage assessments are still in the very early stages, “we know this is a very vulnerable area, higher in poverty” than the one hit by Cyclone Idai, Red Cross spokeswoman Katie Wilkes said.
