NASA Watching Issac's Approach to U.S. Gulf Coast

28.08.2012
NASA satellites have been providing valuable data to forecasters at the National Hurricane Center watching the development and progression of powerful Tropical Storm Isaac as it heads for landfall.

The Moderate Resolution Imaging Spectroradiometer (MODIS) instrument on NASA's Aqua satellite captured this visible image of Tropical Storm Isaac on Aug. 27 at 3:00 p.m. EDT is it was moving northwest through the Gulf of Mexico.

Issac's large reach is seen by its eastern cloud cover over the entire state of Florida. At the same time, the Atmospheric Infrared Sounder (AIRS) instrument on Aqua captured infrared data on Isaac's clouds. Cloud top temperatures were colder than –63F (-52C) around the center of circulation and the western quadrant of the storm, and in a large band of thunderstorms east of the center of circulation, over Florida and parts of Cuba. That's where the strongest storms and heaviest rainfall was occurring.

On Aug. 28 at 8:40 a.m. EDT, a visible image of Tropical Storm Isaac taken from NOAA's GOES-13 satellite showed the huge extent of the storm, where the eastern-most clouds lie over the Carolinas and the western-most clouds are brushing east Texas. The image was created by the NASA GOES Project at the NASA Goddard Space Flight Center in Greenbelt, Md. Tropical-storm-force winds extend outward up to 205 miles (335 km) from the center of circulation, making the storm about 410 miles in diameter.

Warnings and watches in effect on Tuesday, Aug. 28, 2012 are many. A hurricane warning is in effect for east of Morgan City Louisiana to the Alabama-Florida Border, including Metropolitan New Orleans, Lake Pontchartrain, and Lake Maurepas. A hurricane watch is in effect for Intracoastal City to Morgan City, Louisiana. Tropical Storm Warnings are in effect from the Alabama-Florida border to the Aucilla River, and Morgan City to Cameron, Louisiana. A Tropical Storm Watch is in effect from east of High Island, Texas to just west of Cameron, Louisiana.

On Aug. 28 at 8 a.m. EDT, Tropical Storm Issac's maximum sustained winds were just under hurricane force, at 70 mph (110 kmh). The center of Tropical Storm Isaac was located near latitude 27.8 north and longitude 88.2 west, only about 105 miles (170 km) south-southeast of the mouth of the Mississippi River. Isaac is moving northwest at 7 mph (11 kmh) and is expected to continue in that direction for the next day or two, but it's speed is expected to fluctuate. The National Hurricane Center noted that the center of Isaac will be near or over the Louisiana coast tonight, Aug. 28, or early on Aug. 29.

Storm surge is a deadly part of any landfalling tropical cyclone. The National Hurricane Center (NHC) is warning that storm surge will be highest from Isaac from southeastern Louisiana to Mississippi, where surge levels are expected between 6 and 12 feet during times of high tide. Alabama's coast may experience surge between 4 and 8 feet, while south-central Louisiana and the Florida panhandle can expect between 3 and 6 feet. Florida's west coast including Apalachee Bay can expect a storm surge between 1 and 3 feet.

The NHC expects hurricane conditions in the northern Gulf Coast warning area during the afternoon of Aug. 28. As conditions worsen, isolated tornadoes are possible as with any landfalling tropical cyclone.

NASA's Tropical Rainfall Measuring Mission (TRMM) satellite has seen large rainfall rates within Tropical Storm Isaac, and those large rainfall rates and slow movement of the storm will lead to high rainfall totals. The National Hurricane Center expects 7 to 14 inches of rain with possible isolated maximum amounts of 20 inches in southeastern Louisiana, southern Mississippi, southern Alabama and the extreme western Florida Panhandle.

Im Focus: Data use draining your battery? Tiny device to speed up memory while also saving power

The more objects we make "smart," from watches to entire buildings, the greater the need for these devices to store and retrieve massive amounts of data quickly without consuming too much power.

Millions of new memory cells could be part of a computer chip and provide that speed and energy savings, thanks to the discovery of a previously unobserved...

Im Focus: Lethal combination: Drug cocktail turns off the juice to cancer cells

A widely used diabetes medication combined with an antihypertensive drug specifically inhibits tumor growth – this was discovered by researchers from the University of Basel’s Biozentrum two years ago. In a follow-up study, recently published in “Cell Reports”, the scientists report that this drug cocktail induces cancer cell death by switching off their energy supply.

The widely used anti-diabetes drug metformin not only reduces blood sugar but also has an anti-cancer effect. However, the metformin dose commonly used in the...

Im Focus: New Foldable Drone Flies through Narrow Holes in Rescue Missions

A research team from the University of Zurich has developed a new drone that can retract its propeller arms in flight and make itself small to fit through narrow gaps and holes. This is particularly useful when searching for victims of natural disasters.

Inspecting a damaged building after an earthquake or during a fire is exactly the kind of job that human rescuers would like drones to do for them. A flying...
