Today’s Image of Africa’s Hurricane Breeding Region


The majority of our mid-season hurricanes begin as disturbances that develop over the northern hemisphere’s low-latitude Africa.  This infrared image shows you activity today at 2 PM Eastern Daylight Time.  The season is not over – to be sure.  The “Trades” throw these systems out into the Atlantic where the increased moisture content of the air (due to evaporation) can then lower the pressure.  If they survive and move on – leaving the western margin of the continent – the warmer water temperatures lower the pressure even more.  These systems have a lot of ocean to traverse before reaching us – thereby giving some of them plenty of time to develop into hurricanes.
