During the surrounding days, fire activity could also be observed in the United Kingdom and in Spain, where the fires had devastating consequences. 3/3

FCI Fire Temperature RGB – 12 July, 16:00 UTC – Several active fires can be identified in the MTG Fire Temperature RGB composite across northern and northwestern France. The largest is located south of Paris, in the Forest of Fontainebleau. 1/3

Under clear sky conditions, the fires appear as bright, radiant flickers on the mostly uniform purple or dark blue land surface. Depending on their temperature, they may appear in shades from red to yellow, or even white when the fire is extremely intense. 2/3

In this satellite photo, the eye of the typhoon can be seen clearly amidst the surrounding wall of clouds. The cloud phase product shows thick water clouds with small droplets in yellow and large droplets in pink. The green colour depicts thin ice clouds. 2/2

Himawari-8 Cloud Phase with Dust – Wednesday 8 July, 03 UTC – Super Typhoon Bavi wreaks havoc in the Northwestern Pacific. It passed Guam as a Category 5 tropical storm and will pass Taiwan as a Category 4, finally making landfall in Southeast China over the weekend. 1/2

Lighter blue is in the areas of a dry boundary layer and darker blue is where the boundary layer has more moisture. For example, the eastern coast of Spain has more moisture due to its closeness to the Mediterranean Sea. To the north, some cirrus clouds are visible in black. 2/2

MTG 24h Microphysics RGB - Tuesday 30 June, 12 UTC In the afternoon of the 30th, the temperatures in Spain and Portugal were generally in the high twenties and low thirties and the weather was mostly clear. The hot ground heated by the sunshine appears in shades of blue. 1/2

🔥The recordings from the EUMeTrain Forest Fires Event Week are now available online! 🔥 The satellite training programme featured plenary, showcase and practical sessions delivered by numerous experts in the field. Check out the recordings here: shorturl.at/cSGp6

The thunderstorm caused flash flooding and travel disruptions in Southern England, even closing Bristol Airport. The convective cell can be seen in the Convection RGB in shades of yellow. Light yellow colour indicates smaller ice particles and potentially a more severe storm. 2/2

MTG Convection RGB - 22 June 2026, 18 UTC - On Monday evening on the 22nd, a large convective multicell formed over Southern UK in the extremely warm and moist airmass rising from the south. During the night, the Met Office reported over 29000 lightning strikes. 1/2

The recording of the June weather briefing, presented by Janika Takala from the Finnish Meteorological Institute, is now available online: youtu.be/c7fUhalV19c

Here, several cells at different stages of development can be observed over central Algeria. Detection performance degrades at high latitudes and toward the edge of the satellite disk, where the viewing geometry becomes increasingly oblique. 2/2

NWC SAF, Rapidly Developing Thunderstorms – 16 June 2026, 08:50 UTC – The product provides object-based information about significant convective cells and classifies them by life-cycle stage, e.g., triggering (yellow or orange), growing (red), mature (purple), decaying (blue).1/2

These disturbances are monitored during the hurricane season as they can travel across the Atlantic and lead to the formation of tropical cyclones. According to the National Hurricane Center, about 85% of major hurricanes (category 3 or more) can be traced to tropical waves. 2/2

6.2 µm WV (color enhanced) – 12 June, 2026, 06:20 UTC – A strong easterly wave situated over West Africa is evident in this water vapor image, seen near the eastern limb of GOES-East’s view. The expanding cirrus canopy marks vigorous deep convection within the tropical wave. 1/2

An upper-level trough is also visible in the 300-hPa geopotential field. High-level, thick ice clouds are shown in white, while warmer air masses with low upper-tropospheric humidity are shown in dark green. 2/2

GOES EAST Airmass RGB + 300z – 4 June 2026, 06:10 UTC - A low-pressure system has formed near the southern tip of South America, and the airmass product clearly reveals an upper-level PV anomaly in the upper layers, depicted in reddish tones. 1/2

Such a synoptic pattern contributed to the development of a heatwave across Europe, with the UK breaking its highest May temperature record. The MTG True Colour RGB combines red, green, and blue visible channels to create realistic colours as perceived by the human eye. 2/2

True Colour RGB - 25 May, 10 UTC - MTG satellite imagery shows mostly cloud-free conditions across large parts of Europe. The absence of cloud cover is consistent with stable anticyclonic conditions and subsidence, which suppress cloud development and favour strong heating. 1/2
