The Nigerian Meteorological Agency (NiMet), has predicted low weather visibility of below a thousand over some parts of the northern region on November 20, 2021.
The dust haze which are expected to affect the northern States such as Borno, Yobe, Jigawa, Kano, Katsina and its environs originated from the Faya Largeau in Chad Republic – a major dust haze source region for Nigeria and indeed the West African Sub-region.
Disclosing this in a statement on Thursday, the General Manager, Public Relations, Muntari Yusuf Ibrahim, said the value scale of significant visibility deterioration over the northern cities on the 20th as stated above would range from 2000-5000 metres with isolated cases of visibility below 1000 metres.
He added that most parts of the central states are expected to be partly cloudy with sunny intervals while the southern states are expected to be cloudy with prospects of isolated thunderstorms.
“Consequently, motorists are advised to drive with caution especially in the extreme northern parts where reduction in visibility is envisaged.
“More attention is expected especially during the early morning period when horizontal visibility is mostly impaired. Hot and dry atmospheric condition associated with harmattan could result in heat exhaustion and dehydration, hence keeping the body hydrated by drinking water is crucial to avoid heat stroke, however temperatures at night could be very low, adequate clothing is therefore essential”, he said.
He noted that the expected reduction in visibility may disrupt flight operations through cancellation and delay of flights; adding that this is for the safety of air travellers.
Ibrahim stressed that the Nigerian Meteorological Agency will continue to monitor the weather and keep Nigerians updated.
