Weather indicators

In addition to the barometer graph (see Uso del profilo Barometro), Suunto Ambit2 has two weather indicators: weather trend and storm alarm.

The weather trend indicator is displayed as a view in Time mode, providing you a quick way to check weather changes.

The weather trend indicator is comprised of two lines forming an arrow. Each line represents a 3-hour period. A change in barometric pressure greater than 2 hPa / 0.59 inHg over three hours triggers a change the direction of the arrow. For example:

	pressure dropping heavily over the last six hours
	pressure was steady, but rising heavily over the last three hours
	pressure was rising heavily, but dropping heavily over the last three hours

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 Ambit2sounds an alarm and flashes a storm symbol when the pressure drops 4 hPa / 0.12 inHg or more during a 3-hour period.

To activate Storm alarm:

1. Keep Next pressed to enter the options menu.
2. Scroll to Alti-baro with Light Lock and enter with Next.
3. Press Next to select Storm alarm.
4. Set the storm alarm On or Off with with Start Stop or Light Lock and accept with Next.

When a storm alarm occurs, pressing any button ends the alarm. If no button is pressed, the alarm repeats once after five minutes. The storm symbol remains on the display until the weather conditions stabilize (pressure drop slows down).

A special lap (called 'storm alarm') is generated when a storm alarm occurs while recording an exercise.
