TRMM Satellite Shows What's Happening Under the Hood of Hurricane Irene's Clouds

NASA's Tropical Rainfall Measuring Mission (TRMM) satellite radar saw the inner core of Hurricane Irene for a fourth time on Friday afternoon, August 25. On Friday afternoon, the TRMM radar showed that the southern half of the eyewall was gone. Some strong precipitation did still exist in the remaining eyewall to the north of the eye.
The weakening of the inner-core precipitation structure that we see as Irene approaches North Carolina is similar to the pre-landfall weakening of the inner-core of Hurricane Isabel in 2003, the most recent hurricane to make landfall in North Carolina's Outer Banks.

The lack of a compact symmetric eyewall suggests that there is relatively little chance of intensification at the time of the satellite overflight. TRMM showed that the highest towering thunderstorms were about 7.5 miles high (12 kilometers).
