“Flood is a natural event and with the increase in climate change activities there will be more floods. This is because climate change is due to increasing temperatures. With increased temperature, the atmosphere will be more pregnant with more water vapour.Director-General, NiMet, Prof. Mansur Bako Matazu, stated this in Abuja at the sidelines of the public release of the 2023 Seasonal Climate Prediction (SCP).
“Flood is a natural event and with the increase in climate change activities there will be more floods. This is because climate change is due to increasing temperatures. With increased temperature, the atmosphere will be more pregnant with more water vapour.
According to the forecast, the earliest onset is likely to occur on or around March 2, 2023 in Bayelsa, Rivers, Akwa Ibom, and their environs.
NiMet also said strong windstorms across the country and sandstorms in the extreme northern states can occur before the onset of rainfall.
Highlighting the forecast, Sirika said: “The annual total rainfall is predicted to be normal to above normal in most parts of the country.
“The rainfall onset date is predicted to be earlier than the long-term average in most parts of the country.
“However, parts of Katsina, Zamfara, Kano, Jigawa, and Yobe in the North, and Cross River, Ebonyi, Imo, and Rivers in the South, are likely to experience a delayed onset.”
On when the rain will start and its intensity, the minister said: “The onset dates will range from March 2 to July 7, 2023.
“The onset is expected to become established in early March from the coastal states of Bayelsa, Rivers, and Akwa Ibom; in April, for the inland states of the South; in May, around the central states; and around July, in the northern states…”
“Parts of Yobe, Jigawa, Kano, Bauchi, Jigawa, Kaduna, and FCT are likely to observe below normal to near normal annual rainfall amounts.
“The annual rainfall amount is expected to range from 420 millimetres (mm) in the far northernmost parts to 3,253 mm in the coastal areas.”
On the likelihood of dry spells, Sirike said: “Dry spell occurrences have characterised our seasons in recent years. In 2023, we should also prepare for its occurrence between June and early July as dry spell lasting between 15 and 21 days is in the forecast, especially from the central parts of the country to the North.
“When compared to the last years, the little dry season (August Break) for 2023 is expected to be less intense. It is expected to last between 14 and 20 days starting from late July, especially over the Southwest of the country.”
On when the rains will stop, he said: “An early End of Season (EoS) is predicted over parts Osun, Ondo, Edo, Delta, Imo, Bayelsa, Rivers, Akwa Ibom, Ogun, Lagos, Yobe, Adamawa, Niger, Nasarawa, and Kogi.
“However, an extended rainfall season is predicted over parts of Gombe, Kaduna, Kwara, Enugu, Anambra, western Ogun, and Lagos.
“The end of season period is expected to range from September 26 till December 25.”
For farmers and those in the Agricultural sector, NiMet said: “The length of the growing season in most places in the country is likely to be near the long-term average, except for some states, like Katsina, Jigawa, and Kano, where shorter than the long-term average length of the growing season is anticipated.
“The season is expected to range from 84 to 283 days. Abuja and surrounding states are expected to witness between 170 and 230 days.”
Speaking on the likelihood of flooding, the agency’s Director General, Prof. Mansur Matazu, said: “Flooding is a natural event, and with the increase in climate change activities, we are going to see more floods.
