area of strong thunderstorms developed around the center of circulation with very cold cloud top temperatures colder than -63 Fahrenheit (-52 Celsius).

On Sept. 27, when NASA's Tropical Rainfall Measuring Mission (TRMM) satellite passed overhead, convection was limited, and rainfall was light around the storm. The TRMM rainfall image showed Nadine had light rainfall surrounding most of the center of circulation. The heaviest intensity of about 20 mm/hour (~0.8 inches) appeared to be located just northeast of the center. That has changed 24 hours later as thunderstorms have re- developed and heavier rainfall appeared in a larger area of the storm.

Twenty-four hours before, Nadine's was a strengthening tropical storm. Strongest maximum sustained winds near 60 mph (95 kmh). thunderstorms with very cold cloud top temperatures Nadine is currently located near latitude 29.6 north (colder than -63F/-52 C) appear in purple surrounding and longitude 34.7 west, about 730 miles (1,175 the center of circulation.
