At 9:26pm on Sunday April 19, 2020, NASA's GPM satellite observed an extremely vigorous convective storm cell embedded within a squall line that had produced tornadoes earlier that evening along the US Gulf Coast. NASA's GPM satellite flew over the portion of this squall line that extended over the Atlantic Ocean, 350 miles (500 kilometers) east of Florida's Coast. The Dual-Frequency Precipitation Radar (DPR) observed a storm cell whose updrafts were strong enough to lift small ice particles into the stratosphere 15.8 km above the ocean surface. Equally remarkable is that the updrafts were

This animation shows rainfall estimates for the region for April 11th - 13th derived from NASA's Integrated Multi-satellite Retrievals for GPM (IMERG) data product, along with NOAA tornado reports (red triangles).
GPM observed the early stages of a strong cyclonic system that developed over northern Africa just off the southern Mediterranean coast on March 11, 2020. The GMI measured heavy rain rates over some parts of Egypt, including the region around Cairo. View fullscreen By March 12, 2020, the cyclonic system that developed over northern Africa had intensified and was nicknamed 'The Dragon' on social media and news outlets, as it caused severe flooding in northern Egypt. Both the GMI and the DPR measured heavy rain rates across two of the storm's bands in this GPM overflight. View fullscreen On
