The Nigerian Meteorological Agency(NiMet), has on Thursday, advised road users to exercise caution and avoid over speeding, especially during early morning period when horizontal visibility is impaired by fog, mist or dust haze.
This is coming on the heels of another dust plume which has been observed over the southern Chad and Niger Republic, and is expected to propagate into the country in the next few hours.
According to the Agency, in a statement signed by the Assistant General Manager, Central Forecast Office,Olaniyan Olumide (Mrs), flight disruptions are also likely during this period especially over the North eastern airports.
“A further deterioration of the horizontal visibilities to values below 1 – 2km over the northern parts of the country with possibilities of visibility less than 1000m (1km) especially over the North eastern cities is expected.
“The horizontal visibility over the central states in dust haze condition is still poor with visibility ranging from 1km – 5km. Some cities over these regions are still expected to have visibility less than 1000m (1Km). No significant change is expected in coming days over the region.
“Over the south, the visibility is currently ranging between 3000m-5000m in hazy condition. Poorer visibility is reported over the coast and places close to water bodies, especially in the early morning due to fog. No significant change is expected in coming days over the region”, she said.
Olumide, further stated that visibility has slightly improved over the northern parts of the country due to the southward propagation of dust into the Central and the Southern cities.
While noting that dust particles are well known for their potential to cause respiratory and cardiovascular health problems, which can also irritate eyes, throat and skin, NiMet advised people allergic to dust to take necessary precautions and seek medical advice if experiencing increased symptoms.
