Rapidly Developing, Strong Storms Tracked Over Night in Conakry

11 November 2013: A very strong thunderstorm developed rapidly just SE of Conakry as the Guinea Total Lightning Detection System caught the rapidly developing, slow moving storm and issued a Dangerous Thunderstorm Alert (DTA) at about 12:30 a.m. The DTA is issued for the intense storm due to the high rate of intracloud (IC) and cloud-to-ground (CG)lightning indicating the storm was capable of high wind gusts, and extremely heavy rain.

The video shows multiple DTAs issued for the city as the storm slowly moved toward the city. After 1 a.m., the storm regenerated and new DTAs were issued for the NE portion of the city as well.

Slow motion:

The slow moving storms allowed for very heavy rain to fall in less than one hour.
