Mauritania’s national meteorological agency issued an alert on the evening of October 23 for significantly reduced horizontal visibility associated with suspended dust and sandstorms. Western areas and the coast were already affected, with conditions expected to spread elsewhere over subsequent days. (ami.mr)

The agency forecast gradual improvement on October 27 and 28. It urged people with asthma or other respiratory conditions, children and older residents to minimize dust exposure. Drivers were advised to slow down, exercise caution in very poor visibility and watch for drifting sand accumulating on major roads. Mariners and fishers were also asked to follow official bulletins.

This was a new warning issued within the briefing period. Its end date is a forecast, not a guarantee that conditions will remain uniform across the country or improve everywhere simultaneously. (ami.mr)
