How are emergency alerts issued in Nigeria?

Short answer. Nigeria has no cell broadcast system and no public siren network. Warnings come from two federal agencies: NIHSA for river floods (Annual Flood Outlook and a high, moderate or low risk level for each state) and NiMet for weather and climate (flash-flood risk advisories and the Seasonal Climate Prediction) ¹³⁵. NEMA and State Emergency Management Agencies relay them ³⁴.

How will I be warned in Nigeria?

There is no national alert that reaches every phone automatically. Phaenyx found no cell broadcast or location-based warning SMS in the sources of the Nigerian Communications Commission (NCC) or NEMA; the NCC's 112 service is for calling for help, not for receiving warnings ⁷. Warnings travel through:

• NIHSA: the Annual Flood Outlook, seasonal bulletins and a flood-risk outlook you can check by state on nihsa.gov.ng ¹. NIHSA's website says it "does not issue emergency alerts" itself; urgent warnings come from the emergency authorities ¹.
• NiMet: the Seasonal Climate Prediction, produced every year and published in English, Hausa, Igbo, Yoruba and Nigerian Pidgin ⁵ (the 2026 edition was released in February ⁴), and short-range advisories such as the flash-flood risk map for 11-20 July 2026, which covered 26 states and the FCT ³.
• NEMA, SEMAs and Local Emergency Management Committees, which pass warnings on through community awareness campaigns and traditional institutions ⁴⁸.

What do NIHSA's flood-risk levels mean?

NIHSA also separates observations, forecasts, seasonal outlooks and official warnings, and labels each item on its site ¹.

Is there an official alert app?

NIHSA publishes the "NIHSA National Flood Intelligence" app for Android, installed from its website: flood and drought forecasts by state and LGA, gauge readings, risk maps and alerts; full-resolution data is for subscribers ². NiMet's website links to a "NiMet Weather" app for weather updates ⁶. Neither replaces a national public-warning system. Our guide on emergency alerts abroad explains how phone alerts work elsewhere.

Are there sirens in Nigeria?

No public siren network or national siren signals were found. Nigeria does not run national siren or phone-alert tests. NEMA organises flood simulation exercises in high-risk communities instead: in 2025, full-scale exercises in Ogbaru (Anambra State) and Wudil (Kano State), and "Exercise Hadin Kai" in Dukku (Kebbi State) ⁴.

What should I do when a flood warning is issued?

NEMA asks residents of flood-prone communities to remain alert, monitor official weather forecasts and early warning information, clear drainage channels, refrain from driving or walking through floodwaters and promptly report emergencies ³. Its Director General urges people to relocate to safer, higher ground whenever there is a threat of flooding ⁸. A battery emergency radio keeps you informed during power cuts; see also flood preparedness.
