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.

During the night and in the afternoon a few clouds are expected. At the break of day clear skies prevail. It is a sunny day. Temperatures as high as 52 °F are foreseen. With UV-Index rising to 15, sun protection is strongly recommended. Overnight into Monday blows a light breeze (4 to 8 mph). Early in the day expect a moderate breeze (12 to 18 mph). Monday afternoon blows a fresh breeze (18 to 25 mph). From time to time gusts could reach up to 30 mph. Winds blowing overnight from Northeast and by day from West. The weather forecast for Ullumalla for Monday is expected to be very accurate.
Pressure: 1018 hPa
Timezone: GMT-03 (UTC -03:00h)

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.

The location marker is placed on Ullumalla. 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.
