Extreme Weather Warning

Experienced sailors know the key indicators that could signal extreme weather. These indicators include the following:

• Lightning Index
• Cape Index for Thunderstorms
• Rain Squalls
• High Gusts
• Fog
• Wind Chill
• Wind against current
• Tropical Cyclones

When doing a quick check on the weather forecast, it’s easy to miss these key indicators, which can often signal extreme weather, even when the averaged forecast conditions are benign. To make sure you don’t miss these extreme weather events, we now have the following alerts.

Forecast Maps & GMDSS Weather Warnings
You can now view the GMDSS (Global Maritime Distress and Safety System) weather warnings overlaid on any of our weather maps.

The text forecasts are analysed in the PredictWind cloud using machine learning. Then each weather system, front and warning region is plotted accurately on the map, giving you a world-first, global view of the GMDSS forecast.

This feature is available on the forecast website, PredictWind App and Offshore App, for Basic, Standard and Pro users.

Forecast Tables
The potential for extreme weather is shown in a new row, called “Warning”. If an event is predicted it is shown with a warning symbol.

Weather Routing
In the weather routing tables, you will see the extreme events with a warning symbol. In addition, on the weather routing map you will also see the extreme event in orange.

Daily Briefing
