Moist Southwesterly winds originating and blowing from the Atlantic Ocean are established and have largely remain unchanged in their Northwards movement within Niger and Chad republics; for today, they remained at Lat. 22.0oN in the Western sector and at Lat. 21.0oN 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 and established and extends a ridge of high pressure into West Africa; allowing more moisture influx into all parts of Nigeria, Niger and Chad republics are sustained.
The satellite imagery of today at 1200GMT shows convective cells developing in the Northeast, in the Central states especially over Jos/Bauchi high grounds; convective cells were also observed over Mambilla plateau and across the border into Cameroon republic, over parts of Edo/Ondo states and the Coastal states of the South-South. Rains/thunderstorms will develop and affect places in the Central states including parts of Abuja this evening/night.
Partly cloudy to cloudy conditions will affect most parts of the Northern states while thundery showers are expected to affect areas in the Northwest and Northeast in the afternoon/evening. Cloudy conditions will prevail in the Central states with chances of afternoon showers 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 rain showers in the mid-morning/afternoon; however, thunder with rains are expected to affect parts of the Southwest, Southeast and areas in the Coastal states during the afternoon/evening periods.
