Moist Southwesterly winds originating and blowing from the Atlantic Ocean are established and have moved further Northwards relative to it’s position of 08/08/2016, within Niger and Chad republics; for today, they have continued to move further North of Lat. 18.7oN in the Western sector, while also moving it's position Northwards 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 has further moved North of Bilma (18.7oN) in Niger republic whilst also continuing it’s movement further North of 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). A westerly trough stagnant over Europe and extends down to induced a surface low pressure centre over the Arabian peninsula, from which a trough of low pressure extends across East Africa into the West African sub-region including Nigeria. The South Atlantic anticyclone (also known as St. Helena high pressure cell) located 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 the Central states of Adamawa/Gombe/Bauchi/Plateau/ Nasarawa/Abuja and parts of Kaduna state; convective cells were also observed over the Mambilla high grounds. Thunderstorms may likely developed in the Central states and will move Westwards to affect places including Abuja this evening/night.
The 0900GMT collective of today, gave rainfalls in the following stations: Kano (60.4mm), Sokoto (30.8mm), Yola (19.2mm), Gombe (less than 0.3mm) Makurdi (4.6mm), Jalingo (22.2mm), Akure (0.6mm), and Port Harcourt (less than 0.3mm) 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. Cloudy conditions will be experienced in the Central states with chances of thunderstorms affecting places especially in the high grounds during the evening/night period. The Southern parts will be mainly cloudy with showers likely to develop in the afternoon; however, thunderstorms are expected to affect places in the Southeast and parts of the Coastal states during the afternoon/evening periods.
