The western edge of the satellite's radar (DPR Ku Band) swath measured the intensity and heights of storms in the eastern side of hurricane Aletta's eye wall. At NASA's Goddard Space Flight Center in Greenbelt, Maryland, a 3-D cross-section view was created looking toward the southwest. That 3-D image showed a few of those tall convective towers were reaching heights above 15 km (9.3 miles). The heat released by condensation within these tall thunderstorms provided fuel for Aletta's intensification.

By Monday, June 11, 2018 at 5 a.m. EDT (0900 UTC), Aletta had weakened to a tropical storm. The center of Tropical Storm Aletta was located near latitude 17.0 degrees north and longitude 116.7 degrees west. That puts the center far from land, about 600 miles (965 km) southwest of the southern tip of Baja California.
