Moist Southwesterly winds blowing from the Atlantic Ocean are established and their position have slightly displaced Southwards compared to that of 12.10.2016, for today, they have moved their position South to Lat. 14.5oN in the Western sector and also displaced South to Lat. 13.5oN in the Eastern sector, within Niger and Chad republics respectively. The South Atlantic anticyclone (also known as St. Helena high pressure cell) located in the Southern Hemisphere is also weakened but the extent of it's ridge of high pressure into West Africa is sustained; allowing moisture influx into far northern parts of Nigeria.
The satellite imagery of today at 1500GMT shows convective cells developing over the Northeast, over Zamfara/Kaduna states in the Northwest, over the Mambilla plateau and extends across the border into Cameroon republic; convective cells also formed over the Central states especially over the high grounds, over some part of the Southwest and over areas in the South-South states. Thunderstorms are likely to develop in the Central states including parts of Abuja this evening/night.
Hot and clear to partly cloudy conditions will affect most parts of the Northern states, however, isolated thunderstorms may affect areas in the Northwest and Northeast. Partly cloudy to cloudy conditions will prevail in the Central states 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 in the morning; however, thunderstorms are expected to affect places across the Southwest and Coastal states during the afternoon/evening periods.
