Hurricane Igor

Hurricane Igor

Hurricane Igor continued its westward trek across the Atlantic Ocean on September 14. At 11:00 a.m. Atlantic Standard Time (AST) on September 14, the U.S. National Hurricane Center (NHC) reported that Igor was located roughly 710 miles (1,140 kilometers) east of the northern Leeward Islands. Igor remained a Category 4 hurricane, with maximum sustained winds of 135 miles (215 kilometers) per hour.

The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite captured this natural-color image of Hurricane Igor at 10:15 a.m. AST (14:15 UTC) on September 14, 2010. As it did the day before, the storm shows the characteristics of a powerful hurricane—spiral arms stretching across hundreds of kilometers, and a distinct eye.

On September 14, Igor was traveling slowly toward the west-northwest. The NHC warned of swells from the storm affecting the Leeward Islands and Puerto Rico over the next couple days, although no coastal watches or warnings were in effect.

The same day that MODIS acquired this image, observations by the Atmospheric Infrared Sounder (AIRS) instrument on NASA’s Aqua satellite detected a 170-degree difference between the frigid cloud tops of Hurricane Igor and the warm sea surface below, which fueled the powerful storm.
