Moist Southwesterly winds originating and blowing from the Atlantic Ocean are established and reaches far into Niger and Chad republics; for today, they have maintained their position to Lat. 19.0oN in the Western sector and also to North of Lat. 18.0oN in the Eastern sector, all outside the country. The Inter Tropical Discontinuity (ITD) which is the indicator to measure the extent of the moist Southwesterly winds is located to North of Bilma (18.7oN) in Niger republic whilst also moving to North of Faya (18.0oN) in Chad republic, both to the Western and Eastern sectors respectively (Both stations are the farthest and Northernmost synoptic observing stations in Niger and Chad republics respectively). The South Atlantic anticyclone (also known as St. Helena high pressure cell) located in the Southern Hemisphere remained established and strengthened, whilst extending it’s ridge of high pressure into West Africa. As the ITD continue it’s Northward movement, more moisture influx into all parts of Nigeria, Niger and Chad republics are sustained.
