NOAA is now highlighting a large region of "Extremely Critical" fire weather conditions Fri near the heart of the severe-to-extreme drought region across interior West, w/expansion into Sat-Sun likely. While existing fires have quieted down today, that lull will be short-lived.

Incredibile and dramatic #heatwave in #Europe as seen from space. The #Copernicus #Sentinel3 Land (not air!) Surface Temperatures map of June 24 shows peaks of 55°C in #Spain and over 50°C (in purple) in #France. #climateemergency
