When NASA's Aqua satellite passed over the newly strengthened Hurricane Beryl on July 6 at 12:25 a.m. EDT (0425 UTC), the MODIS instrument or Moderate Resolution Imaging Spectroradiometer, analyzed the storm in infrared light. The infrared light provided temperature data that revealed how cold cloud tops were in the storm. The higher the cloud top, the colder, and the stronger the uplift in the storm. MODIS found coldest cloud top temperatures near minus 70 degrees Fahrenheit (minus 56.6 degrees Celsius) around the center, and as cold as minus 50 degrees Fahrenheit (minus 45.5 degrees Celsius) in fragmented bands of thunderstorms wrapping into the center.

Beryl is a compact hurricane. Hurricane-force winds extend outward up to 10 miles (20 km) from the center, and tropical-storm-force winds extend outward up to 35 miles (55 km).
