Moist Southwesterly winds blowing from the Atlantic Ocean are established and their position have moved Southwards in the past 24hours within Niger and Chad republics; for today, they have moved to Lat. 16.6oN in the Western sector and to Lat. 15.0oN in the Eastern sector, all outside the country. The South Atlantic anticyclone (also known as St. Helena high pressure cell) located in the Southern Hemisphere remain active but continue to reduce in strength whilst the extent of it's ridge of high pressure into West Africa is diminished; hence moisture influx into all parts of Nigeria are sustained but decreased in both Northern Niger and Chad republics.
The satellite imagery of today at 1500GMT shows convective cells developing in the Northeast, in the Central states especially over Jos/Bauchi high grounds and extending into Kaduna/Katsina/Kebbi/Zamfara states; convective cells also form over Mambilla plateau in Taraba and extends into parts of the Southeast and across the border into Cameroon republic, over parts of the Southwest and across the Coastal states of the South-South. Thunderstorms are likely to develop in the Central states including parts of Abuja this evening/night.
Partly cloudy conditions will affect most parts of the Northern states while thundery showers are expected to affect areas in the Northeast in the afternoon/evening. Partly cloudy to cloudy conditions will prevail in the Central states while thunderstorms are expected to affect places especially in the high ground areas during the evening/night period. The Southern parts will be mainly cloudy with chances of rains in the morning; however, thunder with showers/rains are expected to affect parts of the Southwest, Southeast and areas in the Coastal states during the afternoon/evening periods.
