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?

During the day blows a light breeze (4 to 8 mph). Winds blowing overnight from Northeast and by day from North. The weather forecast for Lost Camp for Wednesday is expected to be very accurate.
Pressure: 1014 hPa
Timezone: PDT (UTC -07:00h)
The location marker is placed on Lost Camp. 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.
