Moist Southwesterly winds originating and blowing from the Atlantic Ocean are established and their position have remained unchanged from that of 01/09/2016 within Niger and Chad republics; for today, they remained around Lat. 18.0oN in the Western sector and at Lat. 17.0oN 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 remain active and extends a ridge of high pressure into West Africa; allowing 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 Southern Borno, in the Central states especially over Jos/Bauchi high grounds; convective cells were also observed over Mambilla plateau which extends into parts of the Southeast and across the border into Cameroon republic, in parts of the Southwest and Coastal states of the South-South. Rains/thunderstorms will likely develop and affect places in the Central states including parts of Abuja this evening/night.
Partly cloudy to cloudy conditions will affect most parts of the Northern states while isolated thundery showers are expected to affect areas in the Northeast in the afternoon/evening. Cloudy conditions will dominate in the Central states with chances of afternoon showers while thunderstorms are expected to affect places especially in the high ground areas during the evening/night period. The Southern parts will be mainly cloudy with rain/rain showers in the mid-morning; however, thunder with rains are expected to affect parts of the Southwest, Southeast and areas in the Coastal states during the afternoon/evening periods.
