Tropical statements
You can read tropical statements including information about tropical weather conditions.
These statements are available for the entire Atlantic and the Eastern Pacific.
Adjusting color codes
You can define the sea surface temperature range and wave height color coding.
The temperature above warm and below cool values is displayed as progressively darker red
and darker blue.
Waves higher than the maximum value are indicated with progressively darker red. Waves
lower than the minimum value are not color coded.
Animating Sirius weather graphics
The NSS evo3 records the weather information you have turned on, and this information can
be used to animate past or future weather conditions. The amount of information available
in the system depends on the amount of weather activity; the more complex it is, the less
time that is available for animation.
You can animate the past or the future, depending on which weather view you have turned
on:
• With precipitation overlay, you can animate for the past and only assume weather
conditions in the immediate future.
• With colored wave height overlay, you can animate the future (the predictions).
When activated, the time for the current graphic animation is displayed in the lower left
corner of the chart panel.
Weather alarms
You can setup lightning or storm alarms to occur when the conditions are within a certain
range of your vessel.
You can also set up an alarm as a severe weather forecast alarm issued for your chosen
marine zone.
A watchbox is defined by the National Weather Service. When the alarm for watchbox is
turned on, an alarm occurs when your vessel is entering or inside a watchbox.
