Moist Southwesterly winds originating and blowing from the Atlantic Ocean are established and have continued to move Northwards within Niger and Chad republics; for today, their position remained at Lat. 21.0oN in the Western sector and to Lat. 20.5oN 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 is active established and strengthened and extends a ridge of high pressure into West Africa. Hence, more moisture influx into all parts of Nigeria, Niger and Chad republics are sustained.
The satellite imagery of today at 1200GMT shows convective cells developing in the Northeast state of Borno, in the Central states especially over Jos/Bauchi high grounds; convective cells were also observed over Mambilla plateau and across the border into Cameroon republic and over parts of the Coastal states of the South-South.
Sunny, partly cloudy to cloudy conditions will affect most parts of the Northern states while thundery showers are expected to affect areas mostly 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 in the high ground areas during the evening/night period. The Southern parts will be mainly cloudy with rain showers in the mid-morning/afternoon; however, thunder with rains are expected to affect parts of the Southeast and areas in the Coastal states during the afternoon/evening periods.
