List of severe weather phenomena

Severe weather phenomena are weather conditions that are hazardous to human life and property.

Severe weather can occur under a variety of situations, but three characteristics are generally needed: a temperature or moisture boundary, moisture, and (in the event of severe, precipitation-based events) instability in the atmosphere.

Atmospheric

 * Fog
 * Haar (fog)
 * Ice fog

Electrical storms

 * Thunderstorm
 * Derecho
 * Multicellular thunderstorm
 * Pulse storm
 * Squall line
 * Storm cell (single-cell)
 * Supercells, rotating thunderstorms
 * Lightning

Fire

 * Wildfire or bushfire (ignition of wildfires is sometimes by lightning strike, especially in "dry thunderstorms")
 * Firestorm
 * Fire whirl, also called firenado and fire tornado

Flood

 * Floods
 * Flash flood
 * Coastal flooding
 * Tidal flooding
 * Storm surge
