Torrential rains usually fall in Sudan between June and October, and the country faces severe flooding every year, wrecking properties, infrastructure, and crops.
The United Nations estimates that heavy rains and floods have affected some 102,000 people since July.
Last year, heavy rains forced Sudan to declare a three-month state of emergency, after flooding affected at least 650,000 people, damaging or destroying more than 110,000 homes.
