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 mostly cloudy and during the day some wet spells with showers are mixed in. The sun will not be visible. There is a high chance of Precipitation near 70%. Temperature highs are likely to reach 79 °F. The UV-Index climbs up to 12, don't forget to use sunscreen when spending the day outside. Overnight into Tuesday light air is noticeable (1 to 4 mph). In the course of day blows a light breeze (4 to 8 mph). Winds blowing overnight from North, in the morning from Northeast and during the afternoon from East. The weather forecast for Arteche for Tuesday can be accurate in parts but deviations are expected. Check again for latest updates.
Pressure: 1012 hPa
Timezone: PST (UTC +08:00h)

By comparing today's temperatures to 40 years of historical data we can see whether today's forecast is unusually warm (red areas) or cold (blue areas). Coloured dots show observed actual temperatures from professional and private weather stations.
The location marker is placed on Arteche. 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.
