Seventeen states, mostly in the northern part of the country will experience heavy rains that may lead to flooding as from Monday.
The seven-day flood advisory from the Nigeria Hydrological Services Agency (NIHSA) will happen between July 21 and July 27.
The agency said the alert followed rising water levels at key river monitoring stations, increasing the likelihood of localised flooding along river channels and floodplains.
NIHSA’s Director-General Umar Mohammed dropped the hint in its National Flood Advisory (Alert No. NFA-2026-200) issued yesterday.
Mohammed listed the flood-prone states as Adamawa, Bauchi, Benue, Borno, Edo, Gombe, Imo, Jigawa, Kaduna, Kano, Kebbi, Nasarawa, Niger, Plateau, Taraba, Yobe and Zamfara.

According to Mohammed, river levels at Saminara on the Karam River, Waya Dam Site on the Waya River and Amber on the Amber River had exceeded watch and warning thresholds.
He said 16 gauging stations nationwide were recording elevated river stages, placing nearby communities at risk of flooding.
Mohammed urged state governments, local authorities and residents of flood-prone communities to take precautionary measures immediately.
NIHSA said Bauchi had the highest exposure, with 1,841 communities, 145 schools, 101 health facilities and eight markets identified as vulnerable.
The agency also identified vulnerable communities and public facilities in Edo, Imo, Kaduna, Plateau and Benue states.
