Moist Southwesterly winds originating and blowing from the Atlantic Ocean are established and moving Northwards relative to it’s position of 06/08/2016, within Niger and Chad republics; for today, they have moved further North of Lat. 18.7oN in the Western sector, while also maintaining it's position at 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 has moved North of Bilma (18.7oN) in Niger republic whilst also sustaining it’s position at Faya (18.0oN) in Chad republic, both to the Western and Eastern sector respectively (These 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) in the Southern Hemisphere remained established and continued to extend it’s ridge of high pressure into West Africa. As the ITD continue it’s Northward momentum, more moisture influx into all parts of Nigeria, Niger and Chad republics are sustained.
The 1500GMT satellite imagery of today, shows convective cells developing over Adamawa/Mambilla high grounds and extending down to parts of the Southeast and across the border into Cameroon republic; convective cells were also observed in the Central states especially over Jos/Bauchi high grounds and parts of the Coastal states of the South-South.
The 0900GMT collective of today, gave rainfalls only in the following stations: Nguru (78.4mm), Iseyin (1.2mm), Ijebu Ode (0.3mm) and Port Harcourt (1.1mm) within the past 24 hours.
Sunny, partly cloudy to cloudy conditions will affect parts of the Northern states while isolated thunderstorms are expected to affect areas in the Northeast in the afternoon/evening.
