A new satellite image of Hurricane Isaac reveals the storm swirling toward the Louisiana coast, obscuring much of the eastern Gulf of Mexico.
The image was captured at 1:35 p.m. CDT (1735 UTC) on Aug. 28 by the Suomi NPP satellite. The orbiter snapped the image between the hurricane's two landfalls last night. The storm first hit land in Plaquemines Parish, La., at 6:45 p.m. CDT (1145 UTC) and then moved back over water for several hours until 2:15 a.m. CDT (0715 UTC), when it made landfall again near Port Fourchon, La.
The Category 1 hurricane is weakening as it moves inland this morning (Aug. 29). As of 9 a.m. CDT (1400 UTC), the storm's maximum sustained winds were blowing around 75 miles per hour (121 kilometers per hour), according to the National Weather Service (NWS). Water overtopped a levee in Plaquemines Parish, causing major flooding.
The center of Hurricane Isaac is now about 40 miles (64 km) southwest of New Orleans, the NWS reported. The storm is expected to move over Louisiana today and tomorrow, bringing rain to southern Arkansas by Friday.
About the size of a small school bus, Suomi NPP orbits the Earth about 14 times each day, observing nearly the entire planet surface. Among its five instruments, the Visible Infrared Imaging Radiometer Suite (VIIRS) is responsible for the detailed, swirling image of Hurricane Isaac.
