NASA sees newborn Tropical Storm Evan causing trouble for American Samoa

13.12.2012
The date 12-12-12 may be numerically significant, but for the residents of American Samoa and Fiji in the South Pacific Ocean, it means a newborn tropical storm named Evan is causing problems. NASA's Aqua satellite and NOAA's GOES-15 satellite both captured imagery of the newborn storm's cloud cover.

Tropical Storm Evan caused regional warnings to be posted on Dec. 12. In American Samoa, a gale warning and storm watch are in effect for Tutuila, Aunuu, Manua and Swains Island.


The AIRS instrument aboard NASA's Aqua satellite captured an infrared image of newborn Tropical Storm Evan over American Samoa on Dec. 12, 2012, at 12:47 UTC (7:47 a.m. EST). The strongest thunderstorms (purple) appear around the center of circulation and in a band of thunderstorms north and east of the center.

The Atmospheric Infrared Sounder (AIRS) instrument aboard NASA's Aqua satellite captured an infrared image of newborn Tropical Storm Evan over American Samoa on Dec. 12, 2012 at 12:47 UTC (7:47 a.m. EST). The strongest thunderstorms with cloud top temperatures exceeding -63F (-52C) appeared around the center of circulation and in a band of thunderstorms north and east of the center. Cloud top temperatures that cold indicate the highest, strongest storms with the heaviest rainfall within the tropical cyclone.

In addition to NASA's Aqua satellite, NOAA's GOES-15 satellite captured a visible image of newborn Tropical Storm Evan on Dec. 12, 2012 at 1500 UTC (10 a.m. EST) that showed a rounded storm.

At 1500 UTC (10 a.m. EST), Tropical Storm Evan had maximum sustained winds near 50 knots (57.5 mph/92.6 kph). Those tropical-storm-force winds extended 45 nautical miles (51.7 miles/83.3 km) from the center. The center of Evan was located near 13.9 south latitude and 173.2 west longitude, about 145 nautical miles (170 miles/268.5 km) west of Pago Pago, American Samoa. Pago Pago is the capital of American Samoa.

The National Weather Service (NWS) in Pago Pago, American Samoa noted in their forecast for Tutuila and Aunuu that the strongest winds are likely to occur there today, Dec. 12, and Thursday, Dec. 13. The NWS forecast calls for northwest winds between 35 and 45 mph (56.3 and 72.4 kph) tonight, and between 40 and 55 mph (64.3 and 88.5 kph) tomorrow, Dec. 14. Sustained winds on Dec. 15 are expected between 30 and 35 mph (48.2 and 56.3 kph). For more updated forecasts, visit: http://forecast.weather.gov/MapClick.php?zoneid=ASZ001.

Evan continues to move to the east and expected to strengthen. Evan is expected to move to the southwest and towards Fiji.

Im Focus: Making lightweight construction suitable for series production

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.

Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...

Im Focus: Wonder material? Novel nanotube structure strengthens thin films for flexible electronics

Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.

"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...

Im Focus: Deep inside Galaxy M87

The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.

Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Im Focus: A Quantum Low Pass for Photons

Physicists in Garching observe novel quantum effect that limits the number of emitted photons.

The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...

Im Focus: Microprocessors based on a layer of just three atoms

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.

Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
