NASA's Aqua satellite passed over Tropical Storm Beryl on July 9 at 2:35 a.m. EDT (0635 UTC) and analyzed the storm in infrared light. The MODIS or Moderate Resolution Imaging Spectroradiometer instrument aboard NASA's Aqua satellite revealed two small areas of strong thunderstorms where cloud top temperatures as cold or colder than minus 70 degrees Fahrenheit (minus 56.6 degrees Celsius). One area was in the eastern Caribbean Sea, the other over the Northern Leeward Islands. Cloud tops with temperatures that cold have the potential to generate very heavy rainfall.

At 8 a.m. EDT on July 9 the National Hurricane Center addressed the remnants of Beryl. NHC noted "An area of showers and thunderstorms associated with the remnants of Beryl is producing locally heavy rainfall and strong gusty winds over the northeastern Caribbean Sea and the northern Leeward Islands."
