The warning was contained in NiMet’s Tuesday Weather Outlook for June 30, 2026, which forecast sustained rainfall across the southern region throughout the day.
According to the agency, continuous rainfall could trigger flash flooding in coastal and low-lying communities, particularly in Lagos and other states along Nigeria’s southern coastline.
The forecast also outlined expected weather conditions across the northern and North Central regions while advising residents and key sectors to take precautionary measures.
NiMet forecast thunderstorms accompanied by light rainfall over parts of Ondo, Ogun, Edo, Lagos, Rivers, Delta, Bayelsa, Cross River and Akwa Ibom states during the morning. The agency added that rainfall would intensify later in the day, with moderate rainfall expected across the entire southern region during the afternoon and evening.
For the northern region, NiMet forecast morning thunderstorms with moderate rainfall over parts of Borno, Adamawa and Taraba states, adding that thunderstorms would later extend to parts of Bauchi, Kano, Jigawa, Katsina, Zamfara, Kaduna, Sokoto, Yobe, Gombe and Kebbi states.
The agency urged residents in affected areas to monitor weather conditions and remain alert as rainfall intensifies during the day.
Across the North Central region, NiMet predicted predominantly cloudy conditions in the morning, with chances of thunderstorms accompanied by light rainfall over parts of the Federal Capital Territory, Nasarawa and Benue states. It added that thunderstorms with moderate rainfall are expected across the region during the afternoon and evening.
For the aviation sector, NiMet advised airline operators to obtain airport-specific weather reports to support safe and efficient flight operations.
The agency said adherence to these safety measures will help reduce risks associated with severe weather conditions.
The 2026 rainy season has been accompanied by repeated incidents of flash flooding across several parts of Nigeria, disrupting transportation, damaging property and raising concerns over urban drainage and flood preparedness.
The government said flooding in Agungi and Ajiran is linked to a major drainage channel that conveys stormwater through Chevron Drive into the Lagos Lagoon, warning that any obstruction increases flood risks.
In September 2025, the state unveiled plans to integrate estate lakes, canals and pumping stations into a Blue-Green Network designed to improve flood management through stormwater retention, flap gates, pumps, wetland restoration and stricter drainage enforcement.
Earlier in June 2026, the National Economic Council (NEC) approved N83.2 billion under the Anticipatory Action Task Force (AATF) to mitigate the impact of anticipated flooding and other climate-related emergencies across Nigeria.
In 2025, President Bola Tinubu approved N16.7 billion for the reconstruction of the Mokwa Bridge in Niger State after it was destroyed by flooding.
The Federal Government also approved N2 billion for the reconstruction of homes affected by the Mokwa flood disaster.
