Nigerian Meteorological Agency (NiMet) has predicted low weather visibility of below a thousand over some parts of the northern region on November 20, 2021 stating that dust haze are expected to affect Borno, Yobe, Jigawa, Kano, Katsina and environs .

The Dust haze originated from the Faya Largeau in Chad Republic – a major dust haze source region for Nigeria and indeed the West African Sub-region.

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. 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. The expected reduction in visibility may disrupt flight operations through cancellation and delay of flights; this is for the safety of air travellers.
