As Europe recovers from an exceptional heatwave and meteorologists continue to monitor the potential for more heat, the PET map helps cities identify heat stress before it becomes a public health emergency.
Heatwaves are among Europe's most significant weather hazards, affecting millions of people as well as infrastructure, agriculture, and energy systems. But what actually causes a heatwave? Why do some persist for days or even weeks? And how do meteorologists forecast them?

Overnight into Wednesday it is mostly cloudy, but most clouds give way on Wednesday morning. For the afternoon it will be cloudy and rainy. The sun will not be visible. With 60% probability of precipitation we are at the upper end of a moderate chance. Temperatures as high as 68 °F are foreseen. Until noon light air is noticeable (1 to 4 mph). For the afternoon blows a light breeze (4 to 8 mph). Winds blowing overnight from Northwest, in the morning from East and during the afternoon from Northeast. The weather forecast for Kobyay for Wednesday can be accurate in parts but deviations are expected. Check again for latest updates.
Pressure: 1007 hPa
Timezone: GMT+09 (UTC +09:00h)
The location marker is placed on Kobyay. 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.
