We are deeply concerned about the recent flash floods in the village of Nyamukubi, Democratic Republic of Congo.

Flash floods can occur without warning, leaving little time to evacuate or prepare. They are often caused by heavy rainfall or rapid snowmelt, and can cause widespread damage to homes, businesses, and infrastructure. In the case of Nyamukubi, the flooding has caused significant damage to roads, bridges, and homes, leaving many families without shelter or access to basic services.

About 50,000 people have been urged to evacuate their homes as floods hit Australia's largest city for the third time this year.

Parts of Sydney have received about eight months of rain in four days.

Roads have been cut off, some houses are under water and thousands have been left without power.

Widespread flooding across Australia - driven by a La Niña weather pattern - has killed more than 20 people this year, many in New South Wales (NSW).

More than 100 evacuation orders have been issued across Greater Sydney for the current emergency.
