NASA satellite and International Space Station catch Earl weakening

Having felt the effects of both increasing wind shear and cooler waters, Hurricane Earl weakened to a Category 2 storm on the Saffir-Simpson scale with winds still powerful at 90 knots (104 mph) as it neared the North Carolina coast. It was at this time that the Tropical Rainfall Measuring Mission (TRMM) satellite captured the data about TRMM's rainfall rates.

The rainfall pattern associated with Earl and was made using data from the TRMM satellite when it flew over the storm on September 3 at 08:22 UTC (4:22 a.m. EDT). Rainbands from Earl were visible over the outer banks, eastern North Carolina, and southeastern Virginia, but the storm no longer has a well-defined eye. TRMM observed moderate rainfall mostly to the north of Earl's center.

Meanwhile, from a second vantage point in space, at the International Space Station, Astronaut Douglas Wheelock caught an image of the eye of the storm on September 3. As the ISS flew over Hurricane Earl Wheelock noted that it looked like magnificent chaos from up there on the Space Station and called it incredibly breathtaking.

At 11 a.m. EDT on Sept. 3, Hurricane Earl's maximum sustained winds were near 85 mph. It was located about 350 miles south-southwest of Nantucket, Mass. near 36.8 North and 73.1 West. Earl's minimum central pressure was 961 millibars, and he was moving north-northeast at 21 mph.

Because Earl is now forecast to track farther away from the coast, many of the watches and warnings have been discontinued, but new watches and warnings are in place. The current watches and warnings in effect include: a hurricane warning is in effect for Woods Hole eastward around Cape Cod to Sagamore Beach Massachusetts, including Marthas Vineyard and Nantucket Island. In addition a Hurricane Watch is now in effect for Nova Scotia, Canada from Ecum Secum westward to Digby.

Earl is expected to weaken further as it continues northward over cooler waters along the Eastern Seaboard. Updates on Earl are available through the National Hurricane Center at www.nhc.noaa.gov and through the NASA Hurricane twitter page.
