Hurricanes appear in SimCity 2000 and the SimCity Creator for DS.

SimCity 2000

Hurricanes destroy random buildings and trigger extreme flooding. They are unstoppable. They can happen randomly if the city is located next to a coast and "no disasters" is left off.

SimCity Creator (DS)

In SimCity Creator (DS), hurricanes have varying speeds, appearing as rainclouds, and may turn roads and open land into water puddles. Very realistic.
