CAIRO (AP) — Sudan issued what it described as a “red alert” warning of potential floods in five provinces along the Nile River, citing rising water levels in its two main tributaries, the Blue and White Nile. The Sudanese irrigation ministry issued the alert Sunday and it remained in effect Monday. The ministry urged residents in Khartoum, River Nile, White Nile, Sennar, and Blue Nile provinces to practice caution as floods may affect agricultural lands and houses.
