A pretty solid 8+ at my place on surfaces not sitting on the ground. And as noted, it's of the heart attack version in how much water it contains.
This will squelch wildfire concerns out west for at least a week, and encourage some greening of the countryside. I am convinced there will not be significant runoff from it, other than from city streets, so it's all going to end up in the ground. Which is good for kurtr, as that's the water that will show up in the wetlands over the course of the summer.
