Moist Southwesterly winds originating and blowing from the Atlantic Ocean are established and their position have oscillated Southwards from that of 03/09/2016 within Niger and Chad republics; for today, they have relocated Southwards to Lat. 18.0oN in the Western sector and to Lat. 16.0oN 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 but is gradually retracting it’s position and extent of the ridge of high pressure into West Africa; moisture influx into all parts of Nigeria are sustained but decreasing in both Northern Niger and Chad republics.
The satellite imagery of today at 1200GMT shows convective cells developing in Northwest states of Sokoto/Kebbi, in the Central states especially over Kogi/Benue/Nasarawa axis; convective cells were also observed over the Mambilla plateau as well as in parts of the Southeast and across the South-South states.
Partly cloudy to cloudy conditions will affect most parts of the Northern states while isolated thundery showers are expected to affect areas in the Northwest in the afternoon/evening. Cloudy conditions will dominate in the Central states with chances of local 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.
