Selon Abdoulaye Diouf, chef de la Pr\u00e9vision et de la r\u00e9duction des risques \u00e0 l\u2019Agence nationale de l\u2019aviation civile et de la m\u00e9t\u00e9orologie (Anacim), ce ph\u00e9nom\u00e8ne reste inhabituel pour un mois d\u2019octobre, p\u00e9riode de transition pr\u00e9c\u00e9dant le retour plus fr\u00e9quent des \u00e9pisodes de poussi\u00e8re \u00e0 partir de novembre.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u00c0 l\u2019origine, des vents forts au niveau du sol en Mauritanie ont soulev\u00e9 des particules de poussi\u00e8re. Celles-ci ont ensuite \u00e9t\u00e9 transport\u00e9es vers le S\u00e9n\u00e9gal par des vents intenses en altitude, autour de 600 m\u00e8tres. \u00ab Les vents forts \u00e9taient beaucoup plus intenses dans l\u2019ouest de la Mauritanie. Ils ont long\u00e9 la c\u00f4te et transport\u00e9 la poussi\u00e8re sur le littoral nord du S\u00e9n\u00e9gal \u00bb, explique le sp\u00e9cialiste.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Cette configuration a particuli\u00e8rement expos\u00e9 l\u2019axe Saint-Louis-Dakar. Selon M. Diouf, la visibilit\u00e9 y a fortement diminu\u00e9, \u00ab passant sous la barre des 1500 m\u00e8tres, avec des valeurs avoisinant 1200 m\u00e8tres \u00e0 certains moments \u00bb. D\u2019autres localit\u00e9s ont \u00e9galement enregistr\u00e9 une visibilit\u00e9 inf\u00e9rieure \u00e0 2500 m\u00e8tres, tandis que les conditions observ\u00e9es \u00e0 l\u2019a\u00e9roport ont \u00e9t\u00e9 particuli\u00e8rement d\u00e9grad\u00e9es. Pour l\u2019expert, les conditions m\u00e9t\u00e9orologiques en amont ont favoris\u00e9 cet \u00e9pisode. \u00ab En Mauritanie, l\u2019insuffisance des pr\u00e9cipitations laisse les sols secs et meubles.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">En l\u2019absence de pluies suffisantes pour humidifier et compacter la surface, quelques jours d\u2019ensoleillement combin\u00e9s \u00e0 des vents forts peuvent suffire \u00e0 soulever les particules \u00bb, a expliqu\u00e9 Abdoulaye Diouf.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Babacar Gu\u00e8ye DIOP<\/strong><\/p>\n","protected":false},"excerpt":{"rendered":"<p>L\u2019\u00e9pisode de poussi\u00e8re, observ\u00e9 vendredi et samedi sur le littoral s\u00e9n\u00e9galais, s\u2019explique par une configuration m\u00e9t\u00e9orologique particuli\u00e8re.
