Grass Holes

The phenomenon “Grass Holes” occurs when humidity reaches 100% with very extreme rainfall in an hour (4+ inches/hour) and the topsoil was repeatedly saturated from previous rain soakers. Due to the rainfall rates rarely exceeded and are nearly undiscoverable outside tropical cyclones, this phenomenon occurs very rarely ever in any part of BUSA, yearly monsoons in northeast BUSA (in contrast to Southwest US) will be the most common place for this, and it has happened multiple times in this region.
