Storm alarm

Storm alarm

A significant drop in barometric pressure typically means a storm is coming and you should take cover. When the storm alarm is active, Suunto Spartan Ultra sounds an alarm and displays a storm symbol when the pressure drops 4 hPa (0.12 inHg) or more during a 3-hour period.

To activate the storm alarm:

  1. Press the middle button to open the shortcut menu.
  2. Scroll down to Alarms and enter by pressing the middle button.
  3. Scroll to Storm alarm and toggle on/off by pressing the middle button.

When a storm alarm sounds, pressing any button ends the alarm. If no button is pressed, the alarm notification lasts for one minute. The storm symbol remains on the display until the weather conditions stabilize (pressure drop slows down).
