Moist Southwesterly winds blowing from the Atlantic Ocean are established and their position have continued their Southwards movement within the past 24hours; for today, they have moved South to Lat. 14.0oN in the Western sector and to Lat. 12.0oN in the Eastern sector respectively, within Niger and Chad republics respectively. The South Atlantic anticyclone (also known as St. Helena high pressure cell) located in the Southern Hemisphere has remained weakened and the extent of it's ridge of high pressure into West Africa is affected; reducing the moisture influx into the northern parts of Nigeria.
The satellite imagery of today at 1500GMT shows convective cells developing over Mambilla plateau and extends across the border into Cameroon republic; convective cells also formed over the Central states especially over the high grounds and over places in the Southwest and across the South-South states. Thunderstorms are expected to develop in places across the Central states including Abuja this evening/night.
Hot and clear to partly cloudy conditions will affect most parts of the Northern states. Partly cloudy to cloudy conditions will prevail in the Central states while isolated thunderstorms are expected to affect places especially in the high ground areas during the evening/night period. The Southern parts will be mainly cloudy in the morning; however, thunderstorms are expected to affect places in the Southwest and Coastal states during the afternoon/evening periods.
