TempestOne allows you to view four different types of stations, each of which is denoted with a different colored wind arrow.
Public/3rd Party Sensors: Sites not maintained by WeatherFlow-Tempest for which we have permission to share data. We cannot validate the quality of siting or the reliability of data from these sensors.
Tempest Systems: Purchasers of our Tempest Weather Systems share their data with us, but we cannot verify proper siting.
WeatherFlow ProNet: Our sensors get the gold-colored arrows because they're the gold standard in design, engineering, and station siting. We place our sensors in the best possible spots to track the weather most important to you, with a special focus on maritime and coastal interests. We also maintain these sensors and have a long-established track record of short and rare downtimes.
WeatherFlow HurrNet: Like the ProNet stations, we install, operate, and maintain these sites. While we pride ourselves on making ProNet sites as durable as possible, we guarantee that HurrNet sites will survive and record data in up to category 3 hurricane-force winds.
When a station goes down, we note this on our maps in two ways.
- Late reporting: If a station has not reported in more than 90 minutes, its arrow turns gray.
- Down Station: If it has failed to report for more than 4 hours, it is marked as offline and shown as an x.
Additional Note: Although meteorological charts generally denote wind direction with barbs pointing to the direction from which the wind is coming, our arrows show the direction toward which the wind is blowing.
