A Hurricane Warning is in effect for Johnston Atoll, the Papahanaumokuakea Marine National Monument from French Frigate and Shoals to Maro Reef. A Tropical Storm Warning is in effect for Papahanaumokuakea Marine National Monument from Nihoa to French and Frigate Shoals.
On Oct. 3 at 5:45 a.m. EDT (0945 UTC) the Moderate Resolution Imaging Spectroradiometer or MODIS instrument aboard NASA's Terra satellite analyzed cloud top temperatures in infrared light. MODIS found cloud top temperatures of strongest thunderstorms ringed around the wide eye. Those temperatures were as cold as or colder than minus 80 degrees Fahrenheit (minus 62.2 degrees Celsius). They were embedded in a large area that circled the eye where cloud top temperatures were as cold as or colder than minus 70 degrees Fahrenheit (minus 56.6 degrees Celsius). Cloud top temperatures that cold indicate strong storms that have the capability to create heavy rain.
