Satellites Track Birth of Tropical Storm Ophelia in Atlantic

NASA and NOAA satellites were watching the low pressure System 98L in the central Atlantic yesterday when it was 1450 miles east of the Leeward Islands.Yesterday, Sept. 20, 2011 at 4:11 p.m. NASA's Aqua satellite flew over System 98L before it became a tropical storm. An infrared image from the Atmospheric Infrared Sounder instrument onboard showed System 98L's strongest thunderstorms and coldest cloud tops (colder than -63F/-52C) were banded north and south of the center of circulation. Those bands of thunderstorms were a sign that the low pressure area was organizing and strengthening….
