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.

Overnight into Tuesday it is foggy or elevated fog occurs. The fog lifts and breaks up a bit on Tuesday morning. Tuesday afternoon a few clouds are expected. The sun will not be visible. Temperatures peaking at 45 °F. Until noon light air is noticeable (1 to 4 mph). Tuesday afternoon blows a light breeze (4 to 8 mph). From time to time gusts could reach up to 16 mph. Winds blowing overnight from Southwest, in the morning from Northwest and during the afternoon from Northeast. The weather forecast for Arrach for Tuesday is expected to be very accurate.
Pressure: 1024 hPa
Timezone: CET (UTC +01:00h)

The location marker is placed on Arrach. This animation shows the precipitation radar for the selected time range, as well as a 2h forecast. 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.
