There are wildfires burning currently about 20 miles to the west. The ground does sink down when you step on it due to previous rains and if you park your vehicles in grassy areas the tires would sink down. But the grasses are dry and brown, trees have leaves which have fallen to the ground due to new growth budding out and this combined with dried out grasses makes for a ripe environment for grass and woods fires to develop if there is a source of fire. The upper 6 inches of soil has some moisture but would dry out quickly if exposed to sufficient warmth.
