The Nigeria Meteorological Agency (NiMeT) through its Central Forcast Office (CFO) has warned against dust drifting into the country which will reduce horizontal visibility, especially in the north.
In a statement released by NiMeT, it said dust was raised over the dust source region (Faya Largeau, Chad Republic) during the morning hours of December 21, 2021.
“This dust advected into Nigeria and reduced horizontal visibility in parts of the north from 500m to 2000m as at December 22, 2021. Another dust plume has been raised on December 22, 2021 and should equally advect into the country.
“The raised dust should advect into the country as from 0600LT of December 23, 2021 and will re-enforce the already existing dust in the atmosphere. Cases of thick to moderate dust haze are expected over the extreme north and parts of the central states.
“Areas expected to be most affected include Yobe, Kano, Jigawa, Katsina, Kaduna, Bauchi, Gombe, Zamfara and parts of Borno where horizontal visibilities should be around 1000m and below.
“Flight operations may be disrupted and airline operators are advised to pick up their flight folders and adhere to regulations, especially at aerodromes in the northern parts of the country.
“Road users should exercise caution while driving along with areas with poor visibility during this period. People with respiratory problems should take caution,” it added.
