When the soils become this saturated, roots can no longer breathe, and followed by the relentless heat and high humidity, roots bake in the soil moisture, compromising their health to the point that some areas of turf die off . Its the worst case scenario.
Cart traffic compacts soil in these conditions and creates an even worse, unrecoverable environment for the roots and turf - damage will show up in few days to a few weeks. So many players tell me that their carts don't cause any damage, but what you see on top of the surface is a very different story compared to the damage below, where the player usually never looks.
Bottom line is that these types of weather conditions by themselves create less than perfect turf , and with any more added stress, such as traffic, only make it worse.
