One of the other groups had a good suggestion of raising the Dangerous Lightning Alert custom values to 50/75/100 flashes per minute. That increase was significantly larger than the default values and based off some of the situations we have seen over the SW OUN cwa, that may not have been high enough. This image below (taken around 2143Z) shows just the 75/100 flash alerts and those are too overwhelming with the amount of polygons.
