Tomas moving away from Fiji Islands after causing damages

18.03.2010
Cyclone Tomas hit the north and east areas of Fiji as a Category 4 Cyclone on the Saffir-Simpson Scale, and has now moved south of them. NASA's Tropical Rainfall Measuring Mission satellite captured an image of the heavy rains that were falling in Tomas during his swath of destruction in the Fiji Islands.

Yesterday, March 17, at 0900 UTC (5 a.m. EDT), Tomas was 710 miles southeast of Nadi, Fiji, near 27.0 South and 174.7 West and was a Category One cyclone. Tomas has maximum sustained winds near 86 mph (75 knots) and was speeding south-southeast at 31 mph (27 knots). Tomas is a large cyclone with hurricane-force winds extending 65 miles from the center, and tropical storm-force winds extending as far as 215 miles from the center. That makes Tomas 430 miles in diameter.

The Fiji Meteorological Service issued bulletin 32 at 2:40 p.m. EDT on March 16, which would be March 17 at 7:40 a.m. Fiji local time. At that time, the tropical cyclone warning for the Fiji group of islands was canceled. However, a Strong Wind Warning remained in force for Southern Lau only. Southern Lau was forecast to experience winds from the southwest to the northwest, waning later today. Tomas is also creating very rough seas with waves up to 23 feet and heavy swells. The rest of the Fiji islands will experience moderate to rough seas today as Tomas continues to track south and away from the islands.

The Tropical Rainfall Measuring Mission satellite, also known as "TRMM" passed over powerful tropical cyclone Tomas near the International Dateline in the South Pacific on March 15 at 2123 UTC (5:23 p.m. EDT). TRMM measures rainfall from space, and the rainfall analysis used data from TRMM's Microwave Imager (TMI) and Precipitation Radar (PR) instruments revealed that Tomas had a large circular eye, and was located about 242 kilometers (150 miles) from Fiji at that time. Tomas was decreasing in intensity but wind speeds were still estimated to be over 105 knots (~121 mph). TRMM detected very heavy rainfall of over 50 mm/hr (~2 inches) mainly in Tomas' southeastern quadrant.

Areas of north and east Fiji encountered winds near 109 mph (175 km/hour) and storm surges. About 17,000 people had gone to the evacuation centers before the storm hit. As a result of damages caused by Tomas, a "state of disaster" was declared in those areas, so that foreign assistance can come into the country. Houses were damaged, electricity, water and sewage systems were affected, and flooding was reported.

The Atmospheric Infrared Sounder instrument on NASA's Aqua satellite captured a visible image of the western half of Tropical Cyclone Tomas as it flew overhead on March 17 at 01:53 UTC (March 16 at 9:53 p.m. EDT), and it showed the storm was still well-organized.

Tomas is now quickly moving southeast and is in cooler waters, which will continue to cause Tomas to weaken. Tomas is also transitioning into an extra-tropical storm.

Im Focus: Exotic quantum states made from light: Physicists create optical “wells” for a super-photon

Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.

Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...

Im Focus: Circular RNA linked to brain function

For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.

While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...

Im Focus: RAVAN CubeSat measures Earth's outgoing energy

An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.

The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...

Im Focus: Scientists shine new light on the “other high temperature superconductor”

A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.

Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...

Im Focus: Scientists improve forecast of increasing hazard on Ecuadorian volcano

Researchers from the University of Miami (UM) Rosenstiel School of Marine and Atmospheric Science, the Italian Space Agency (ASI), and the Instituto Geofisico--Escuela Politecnica Nacional (IGEPN) of Ecuador, showed an increasing volcanic danger on Cotopaxi in Ecuador using a powerful technique known as Interferometric Synthetic Aperture Radar (InSAR).

The Andes region in which Cotopaxi volcano is located is known to contain some of the world's most serious volcanic hazard. A mid- to large-size eruption has...
