The Sudanese Meteorological Authority issues an orange alert, warning eight states of heavy rainfall and severe dust storms.
Forecasters say torrential rain and strong winds are expected to affect central, southern and western Sudan through Wednesday morning.
Monsoon winds are also expected to trigger sandstorms across northern states, reducing visibility and creating dangerous travel conditions.
Weather officials warn the severe conditions could lead to flash floods and pose significant risks to public safety.
Authorities urge residents to avoid low-lying areas, drive with caution and stay away from flooded roads.
