My clothes are wet from the rain.
Sign 'clothes,' then perform the sign for 'wet' by pulling both open hands downward while bringing your fingers and thumbs together, as if feeling the dampness on the fabric.

Careful, the floor is wet.
After signing 'careful' and 'floor,' use the downward pulling motion of 'wet,' closing your fingers to your thumbs to emphasize the water present on the surface.

The dog is all wet!
Sign 'dog,' then use both hands to sign 'wet.' You can exaggerate the downward pulling and closing motion slightly to show that the dog is completely soaked.
