Buildings adapted to the country's usually dry weather have been demolished after several weeks of rain and around 150,000 Sudanese are affected by the extreme weather.
According to the UN, the figure is expected to rise to nearly half a million at the end of the rainy season, which extends into September.

According to authorities, 89 people have died and 50,000 homes have been destroyed in connection with the disaster.
Thousands are without shelter and residents in, among other places, the city of Al Managil state that they have limited access to drinking water and food.
- All assistance, protection or transport takes place through the local volunteer effort.
The government has not offered any help, city chief Altayib Abdallah said on Wednesday.
Over the weekend, however, the government promised to send aid to Al Managil, which includes clearing the ditches, fixing the main road to the area and arranging for compensation.
State of exception announced
The authorities in Sudan have declared a state of emergency in a third of the country's provinces.
"Sudan is particularly vulnerable to the effects of the climate crisis, with decades of extreme weather eroding the nation's resilience to disasters such as floods and droughts," the NGO said in a statement.
