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 Sunday the weather is changing with a mix of clear and cloudy skies and a chance of showers. On Sunday morning no more showers are expected but it remains partly cloudy. Sunday afternoon a few clouds are expected. The sun will not be visible. With 60% probability of precipitation we are at the upper end of a moderate chance. Temperature highs are likely to reach 83 °F. With UV-Index rising to 8, sun protection is strongly recommended. On Sunday blows a light breeze (4 to 8 mph). Winds blowing at night and in the morning from South and during the afternoon from West. The weather forecast for Puo Town for Sunday can be accurate in parts but deviations are expected.

Pressure: 1013 hPa
Timezone: GMT
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 Puo Town. 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.
