Afternoon Sea Breeze Storms Tracked in Sierra Leone and Liberia

November 4, 2013

4 November 2013, 20:00 UTC: Afternoon and evening storms were being tracked by Guinea meteorologists as they began forming along a sea breeze convergence zone in Sierra Leone and Liberia. Total lightning detection allowed forecasts to see a fairly extensive line of storms about 20 miles inland from the coast. PulseRad simulated radar showed these storms very well.
