NIHSA can name the school, the clinic and the market that floodwater will reach next week. Nobody in government can tell you, with that same precision, when the evacuation trucks arrive.

In Bauchi State right now, there's a teacher who has already lived this once this year. Her school sits close enough to the Karam River that she knows exactly what it means when the Nigeria Hydrological Services Agency talks about water levels at Saminara. She doesn't need a map. She's heard this warning before. She's about to hear it again.

On Tuesday, NIHSA placed 17 states on medium flood alert for the week running from 21 to 27 July. This is the third such advisory in three weeks. Director-General Umar Mohammed didn't speak in generalities. He named the exact river stations where water had crossed warning thresholds, Saminara on the Karam River, the Waya Dam site, Amber on the Amber River. Sixteen gauging stations across the country are showing elevated levels right now.

The advisory gets specific in a way most flood warnings don't.

Bauchi has 1,841 communities at risk, including 145 schools, 101 health facilities and eight markets. Edo has 148 communities, 131 schools and 123 health facilities exposed. Imo has 415 communities, 423 schools and 198 health facilities on the list. Plateau has 205 communities and 137 schools. This isn't a vague warning about rain. It's a named inventory of the exact buildings children sit in and the exact clinics mothers walk their babies to.

Think about what that precision means if you're the parent reading it. NIHSA isn't guessing. Somewhere in Abuja, someone has already counted your child's school. They know it by name.

What NIHSA cannot tell you, and what its mandate doesn't cover, is what happens after the warning leaves its desk. That job belongs to the National Emergency Management Agency, the State Emergency Management Agencies, and the local governments Mohammed directed to "begin immediate evacuation." His advisory tells them to. It cannot make them.

Earlier this month, a separate NIHSA alert covered 14 states for the week before this one. Before that, the Federal Ministry of Environment issued its own alert for 26 states and the FCT. Three warnings in three weeks, each one naming different but overlapping communities. Each one asks the same local governments to move people who often have nowhere else to go. Many don't have transport to get there even if they did.

NIHSA's job ends the moment the advisory is published. It has done its work. It found the rising water before it reached anyone's doorstep, which is exactly what a hydrological agency is supposed to do. The failure, if it comes, will not be a failure of forecasting. It will be a failure of everyone downstream of the forecast. The state government that doesn't move trucks. The local chairman who doesn't clear the drainage NIHSA also asked for. The family with no relative to stay with and no money for transport out.

You already know how this ends if nothing changes. It ends the way it ended in June. Water rises, someone posts photos of a submerged school, and a minister issues a statement about lessons learned. Then the cycle starts again with the next advisory, precise down to the school name, and the same gap between the warning and the walk to safety.

The state has built one system that works exactly as designed. It is the system built to protect people that keeps missing.
