The two companies have come together to tackle one of the most pressing challenges of our time: keeping cities safe from flooding in an era of intensifying climate extremes.
In the first part of this guide, we explored how numerical weather prediction models simulate the atmosphere, from observational data and data assimilation to model grids and parameterisation. Modern forecasting goes further by combining global and regional models, ensemble systems and advanced computational techniques to better predict weather and its uncertainty.

The night and the afternoon the weather is changing with a mix of clear and cloudy skies and a chance of showers. Before noon it will be cloudy and rainy. The sun will not be visible. There is a high chance of Precipitation near 70%. Temperatures peaking at 47 °F. Overnight into Tuesday blows a light breeze (4 to 8 mph). Early in the day a gentle breeze is expected (8 to 12 mph). In the afternoon blows a fresh breeze (18 to 25 mph). From time to time gusts could reach up to 38 mph. Winds blowing overnight from Southwest and by day from West. The weather forecast for Islas Wallis for Tuesday can be accurate in parts but deviations are expected. Check again for latest updates.

The animation shows the wind conditions of the storm at 200m above ground, which corresponds well with expected gusts at the surface. Choose other time steps to see the forecast of the storm.
The location marker is placed on Islas Wallis. Orange crosses indicate lightning. Data provided by nowcast.de (available in USA, Europe, Australia). Drizzle or light snow fall might be invisible for the radar. Precipitation intensity is colour coded, ranging from turquoise to red.

The real-time satellite image combines visible light during daytime with infrared radiation during nighttime. At night, the image is not dark as infrared radiation can detect temperature differences. Unfortunately, low clouds and fog are difficult to distinguish from ground temperatures and thus can be almost invisible during the night. Meteosat satellite images for Europe are updated in real-time every 5 minutes. GOES-16/GOES-17 (North & South America) and Himawari (Asia) images update every 10 minutes.
Precipitation is estimated from radar and satellites. Precipitation estimates from satellites are less accurate at night than during daytime.
