Another instrument on NASA's Aqua satellite measured the cloud top temperatures of Tomas' thunderstorms, and revealed very high, cold thunderstorms (as cold as minus 63 degree Fahrenheit) surrounding Tomas' 34-mile in diameter-wide-eye. The Atmospheric Infrared Sounder (AIRS) instrument showed forecasters that the thunderstorm "engine" in Tomas' center was very powerful with strong thunderstorms, dropping heavy rainfall.
Tomas has already caused damages for residents of the northern Fiji islands. Damage reports are still coming in, but power losses and flooding have been reported. Evacuations have taken place in Labassa, Wainiika, Nuku and Vatu because of flooding. Other reports indicate that schools and government buildings have been closed. Tourists were evacuated and flights have been temporarily canceled to and from Fiji's main airport.
At 0828 UTC March 15 (4:28 a.m. EDT), Cyclone Tomas was packing maximum sustained winds near 120 mph (105 knots). The center of the storm was approximately 200 nautical miles northeast of Nadi, Fiji, near 16.1 South and 179.5 West. Tomas is moving south at 7 mph (6 knots). Tomas' estimated minimum central pressure was 930 millibars.
Cyclone-force winds extend 40 miles out from the center, while tropical storm-force winds extend out 150 miles from the center, making the storm 300 miles in diameter. Tomas' eye is 30 nautical miles (34 miles) in diameter.
Infrared satellite imagery shows that Tomas has maintained its banding or wrapping around of thunderstorms around the storm's low-level center of circulation. As Tomas continues to track in a southerly direction over the next day and a half, it is forecast to intensify a little (due to the warm ocean waters it will be passing through), then will run into increasing wind shear which will weaken the storm.
The Fiji Meteorological Service issued a forecast track map for Tomas at: www.met.gov.fj. The forecast brings Tomas's center between Cicla, Lakebda, and Kabrana to the east, and Labesa, Suva and Kadavu to the west over the next day. For the latest advisories and warnings from the Fiji Meteorological Service: http://www.met.gov.fj/advisories.html. Residents of the southern Fiji islands should monitor watches and warnings.

Satellites in near-Earth orbit are at risk due to the steady increase in space debris. But their mission in the areas of telecommunications, navigation or weather forecasts is essential for society. Fraunhofer FHR therefore develops radar-based systems which allow the detection, tracking and cataloging of even the smallest particles of debris. Satellite operators who have access to our data are in a better position to plan evasive maneuvers and prevent destructive collisions. From April, 25-29 2018, Fraunhofer FHR and its partners will exhibit the complementary radar systems TIRA and GESTRA as well as the latest radar techniques for space observation across three stands at the ILA Berlin.
The "traffic situation" in space is very tense: the Earth is currently being orbited not only by countless satellites but also by a large volume of space...
An international team of researchers has discovered a new anti-cancer protein. The protein, called LHPP, prevents the uncontrolled proliferation of cancer cells in the liver. The researchers led by Prof. Michael N. Hall from the Biozentrum, University of Basel, report in “Nature” that LHPP can also serve as a biomarker for the diagnosis and prognosis of liver cancer.
The incidence of liver cancer, also known as hepatocellular carcinoma, is steadily increasing. In the last twenty years, the number of cases has almost doubled...
In just a few weeks from now, the Chinese space station Tiangong-1 will re-enter the Earth's atmosphere where it will to a large extent burn up. It is possible that some debris will reach the Earth's surface. Tiangong-1 is orbiting the Earth uncontrolled at a speed of approx. 29,000 km/h.Currently the prognosis relating to the time of impact currently lies within a window of several days. The scientists at Fraunhofer FHR have already been monitoring Tiangong-1 for a number of weeks with their TIRA system, one of the most powerful space observation radars in the world, with a view to supporting the German Space Situational Awareness Center and the ESA with their re-entry forecasts.
Following the loss of radio contact with Tiangong-1 in 2016 and due to the low orbital height, it is now inevitable that the Chinese space station will...
