Heavy rain flooded roads and destroyed buildings across Senegal over the weekend, and the government said several people were killed and that more rain is coming. Flash floods in the capital, Dakar, and other areas disrupted traffic, and Prime Minister Ahmadou Al Aminou Lo warned that the school year, due to start this week, could be postponed if the water does not recede.
The floods come less than four weeks before Dakar hosts the 2026 Summer Youth Olympics, which start on October 31.
Deaths reported in Dakar and Matam
Senegal’s Interior Ministry reported deaths and injuries in Dakar and in Matam, a town in the northeast. It said a building collapsed in Kaolack, a town in the south. The reports did not give a death toll.
Local media reported that a mother and her child died in the Parcelles Assainies area of Dakar after their home flooded.
More rain forecast for Monday to Wednesday
Lo said there is a high probability of more rain on Monday, Tuesday and Wednesday. The forecast covers the same days on which many families would be preparing children for the start of term.
He said the school year could be postponed if floodwaters have not receded. The government has not yet announced a new date.
How much rain fell
Senegal’s meteorological agency, ANACIM, published rainfall totals for 24 hours. Rufisque, a town just outside Dakar, and Ranerou, in the Matam region, each recorded 142 mm. Dakar’s Yoff district recorded 138 mm.
The two places with the highest totals are about as far apart as two parts of the country can be, which suggests the rain covered a wide area and was not limited to the capital.
For comparison, after floods in Dakar in 2020, then-Water Minister Serigne Mbaye Thiam said 124 mm of rain had fallen, about what the city normally gets over the whole rainy season from July to September. The measuring stations and years differ, so the figures are not an exact match. Even so, both totals reported this weekend are above that 2020 number, and they were recorded within one day.
The Youth Olympics clock
Senegal is preparing to host the first Youth Olympic Games ever held in Africa. The event runs from October 31 to November 13, 2026.
The government expected flooding to be a risk for the event. On July 3, Lo chaired an interministerial meeting on flood preparedness and management, and the government approved measures to protect the venues and infrastructure. A dedicated task force was set up to handle flooding and waste at competition and accommodation sites, according to Ecofin Agency
That work followed Law No. 2026-381 of May 19, 2026, which strengthens the role of local authorities in flood prevention and management. The law is not specific to the Games. The task force works with the organising committee and the International Olympic Committee’s coordination commission.
This weekend’s rain is the first major test of those plans. The reports so far do not say whether any Olympic venues were affected, so that question remains open.
A problem that comes back each year
Floods in Dakar are not new. In 2020, the government faced criticism over a slow response to flooding that killed at least six people. A local resident told FRANCE 24 at the time that every flood brings food rations, but that what residents need is drainage and sanitation.
Dakar has a record of flooding after heavy local downpours, according to a European Space Agency hazard map, which classes the risk using flood events over the past 10 years. This weekend adds another event to that record.
What happens next
Three things will show how serious the situation is. The first is the rainfall on Monday, Tuesday and Wednesday, and whether floodwater drains from the streets of Dakar and Matam. The second is the government’s decision on the start of the school year. The third is whether the Interior Ministry publishes a full death toll and the number of damaged buildings.
With the Youth Olympics less than four weeks away, how quickly Dakar’s roads reopen will also be watched by organisers, athletes and visitors planning to travel.
