Moist Southwesterly winds originating and blowing from the Atlantic Ocean are established and advancing far into Niger and Chad republics; for today, they have moved further Northwards to around Lat. 21.0oN in the Western sector and Lat. 20.0oN in the Eastern sector, all outside the country. A surface low pressure centre located over the Arabian peninsula is still active and extends a trough of low pressure 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 strengthened and extends a ridge of high pressure into West Africa. As a result, 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 Adamawa/Gombe states, in the Central states especially over the Jos/Bauchi high grounds and parts of Kwara/Niger states; convective cells were also observed in the Mambilla plateau down to areas in the Southeast and across the border into Cameroon republic, over inland of the Southwest and parts of the South-South states. Thunderstorms are likely to develop in the Central states and will affect places including Abuja, this evening/night.
Sunny, partly cloudy to cloudy conditions will affect most parts of the Northern states while thundery showers are expected to affect areas in the 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 the high ground areas during the evening/night period. The Southern parts will be mainly cloudy with rain showers likely to develop in the afternoon; however, thunder with rain are expected to affect parts of the Southeast and areas in the Coastal states during the afternoon/evening periods.
