They will be flying again in Benin, the Edo state capital.

It's not the famous witches this time but the anopheles and its relatives.

When mosquitoes bite they leave the individual with ‘plasmodium falciparum’, a protozoan parasite that causes malaria.

Malaria could be deadly, especially for children, a reason the Nigerian Meteorological Agency (NiMet) is giving this early warning.

It is also advising the health sector to be better prepared to deal with the deadly disease.

In a 2017 Seasonal Rainfall Prediction, the agency warned that some states in Nigeria would experience increase in the mosquito population, which would pose a big threat to communities.

"In 2017, locations including Benin City and to its north are likely to experience high to extreme mosquito population throughout the year.

"To the north of Benin City, risk in mosquito population is expected to grow with rainy season months.

"In 2017, we expect lowest mosquito population risk occurring in areas north of Yelwa, Zaria, Bauchi and Yola axis.

"NiMet hopes to develop partnership with health sector and others involved in malaria control through partnership on data collection on mosquito population and infected population to improve its malaria forecast model," the agency’s report read.

The News Agency of Nigeria  reports that NiMet had predicted that neutral El-Nino Southern Oscillation (ENSO) – variation in winds and sea surface temperatures phase, was most likely to dominate the January to June weather system across the country in 2017.

It said that the ENSO phase was expected to give way to a dominant El-Nino phase later this year.
