For the first time in recorded history, downtown San Francisco was included in a tornado warning on Saturday as severe storms swept through the city, just one week after a tsunami warning triggered widespread panic in the region.

San Francisco residents were woken up by a tornado warning early Saturday morning during a powerful storm system that battered the region with heavy rain and wind.

Less than two weeks after a tsunami warning, residents were jolted awake before 6 a.m. to consider a new potential disaster scenario.
