At NASA's Goddard Space Flight Center in Greenbelt, Maryland, the GPM satellite's radar (DPR Ku Band) data were used to create a 3-D structure of precipitation within Mekunu. The 3-D cross-section view of the tropical cyclone's precipitation revealed that powerful convective storms southwest of Mekunu's center were reaching heights of about 16 km (9.9 miles). GPM's DPR showed that some heavy downpours were returning radar reflectivity values greater than 59 dBZ to the satellite. GPM is a joint mission between NASA and the Japan Aerospace Exploration Agency, JAXA.

At about 5:33 p.m. EDT (2133Z) on May 23, NASA-NOAA's Suomi NPP satellite flew over Mekunu. Infrared data showed intense convection and tropospheric gravity waves. In addition, the First Quarter moon (54% Illumination) provided enough side lighting to show the intense convection to the east of Socotra Island, as well as some tropospheric gravity waves near the eye. In the night-time image, lightning streaks were also seen around the storm.
