Moist Southwesterly winds blowing from the Atlantic Ocean are retracting and their position have continued their Southwards movement within the past 24hours; for today, they have moved to the South of Lat. 10.5oN in the Western sector and also moved to South of Lat. 10.0oN in the Eastern sector respectively, within Nigeria. The Subtropical anticyclone (also known as Azores high pressure cell over Africa) located in the Northern Hemisphere is strengthened. A trough extending from the mid-latitude is located over Niger and is responsible for generating this dust episode. Dust haze with poor visibilities were observed in stations across Niger republic and Northern Nigeria.
The satellite imagery of today at 1500GMT shows convective cells developing over areas in the Southwest and the South-South states. Dust haze with visibilities as low as 300m and 800m were observed in Niger and Nigeria respectively during the day.
Dust haze in poor visibility will continue to affect most parts of the far Northern states during the day with some improvement during the night. Sunny and hazy, fair to partly cloudy conditions will prevail in the Central states. The Southern parts will be mainly cloudy in the morning; however, thunderstorms are expected to affect places in the Southwest and the Coastal states during the afternoon/evening periods.
