When it has rained, "rain slashed, knifing the evening with black."

Outside, thunder rolled through the foothills and rain slashed against the windows.

The rain slashed in at them, and thunder rumbled in the distance.

He glanced at the window, where the rain was slashing across the glass in slanting streaks.

The slanting rain, coming from the northwest, slashed at his face.

The icy rain slashed at him, and he stumbled again on the slippery pavement.

The rain slashed like shrapnel against my face as I stared up at an abandoned church.

The rain was slashing his face and he squinted against the pain.

He leaned heavily against the window and watched the rain slash hard diagonal lines across the glass.
