Moist Southwesterly winds originating and blowing from the Atlantic Ocean are established and have continued to maintain their Northwards movement within Niger and Chad republics; for today, they their position remained at Lat. 21.0oN in the Western sector and to Lat. 20.5oN 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 have remained established and strengthened and extends a ridge of high pressure into West Africa. Hence, more moisture influx into all parts of Nigeria, Niger and Chad republics are sustained.

The satellite imagery of today at 1500GMT shows convective cells developing in Borno state, in the Central states especially over Jos/Bauchi high grounds; convective cells were also observed over Mambilla plateau down to areas in the Southeast and across the border into Cameroon republic and over parts of the Coastal states of the South-South.
