Afternoon Sea Breeze Storms Tracked in Sierra Leone and Liberia
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.
The Guinea Total Lightning Detection Network was showing wide spread lightning occuring with several storms producing frequent lightning at a rate to cause the automated alerting system to produce Dangerous Thunderstorm Alerts (DTAs).
The image below shows the most intense of these storms along the Sierra Leone and Liberia border.
The Guinea TLDN detected lightning frequency over 20 flashes per minute and issued a DTA for the storm. This storm was producing heavy rain, gusty winds and very heavy downpours.
