Thunderstorm black outline icon

About the Thunderstorm black outline icon

A single billowing cloud with three rounded humps sits above a tall zigzag lightning bolt that starts inside the cloud body and stabs down past its base. The bolt dominates the lower half, so the icon reads as an active electrical storm rather than plain rain. Use it in weather apps and forecast strips, severe weather alerts, aviation and sailing dashboards, power outage notices, and energy or high-voltage presentations.

The bolt is drawn in open outline with a wide angular kink, cutting through the cloud's bottom edge so the two shapes interlock instead of merely stacking. Cloud curves stay soft against the sharp bolt for contrast. Pair it with rain, snow, sun and wind icons for a complete forecast row; it holds up well down to 16 px.

This is the black outline version of the thunderstorm icon: even, monoline strokes that stay crisp at small sizes and suit clean, minimal interfaces, wireframes and light backgrounds.
