Moist Southwesterly winds blowing from the Atlantic Ocean are retracting and their position have continued to move Southwards within the past 24hours; for today, they have moved to the South of Lat. 10.3oN in the Western sector and also moved to South of Lat. 09.4oN 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 still located over Niger republic. 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, Southeast and the South-South states. Dust haze with visibilities as low as 700m were observed in both Niger and Nigeria during the day. The dust spell have been advected into Central states with visibility reducing to 2000m in places.
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 affect areas in the Central states, while daytime visibility of 1000 – 2000m in dust are expected in places. The Southern parts will be partly cloudy to cloudy in misty morning; however, isolated thunderstorms are expected to affect places in the Southwest and the Coastal states during the afternoon/evening periods.
