NASA's Aqua satellite passed over Tropical Depression 30W, known locally as "Wilma," on Nov. 4 at 0529 UTC/12:29 a.m. EDT/1:29 p.m. Philippines local time as it was moving through Visayas, central Philippines.
The coldest cloud tops with potential for heavy rainfall were as cold as -63F/-52C and covered Visayas and extended west to Palawan. Palawan is an island province of the Philippines, west of Visayas.
The Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) noted on Nov. 4 that the depression weakened to a low pressure area by 5 p.m. local time. At that time the center of the low was about 9.3 miles/15 km southwest of Tagbilaran City and was bringing rains and gusty winds to Visayas and Mindanao.
Local radar at 1:30 p.m. EST/18:30 UTC on Nov. 4/2:30 a.m. local time, Nov. 5, showed the heaviest precipitation had moved west of Visayas and was in part over northern Palawan as it headed further west into the South China Sea.
At 2 p.m. local time/1 a.m. EST, PAGASA issued the final bulletin on former Tropical Depression 30W. At that time, the center of the low pressure area was about 19.8 miles/32 km southeast of Tagbilaran City.
Now that former Tropical Depression 30W was wrapping up for the Philippines, residents of Visayas are keeping a close eye on Tropical Storm Haiyan moving their way from the east.
This isn't the end of Tropical Depression 30W, however. Now that it is in the warm waters of the South China Sea, the Joint Typhoon Warning Center expects it to re-strengthen. On Nov. 4 at 1500 UTC/10 a.m. EST, maximum sustained winds were near 30 knots/34.5 mph/55.5 kph and it had regained its status as a depression. It was located near 13.4 north and 93.4 east, about 267 nautical miles east of Puerto Princesa, Philippines. It was moving quickly to the west at 21 knots/24.1 mph/38.8 kph and is expected to reach tropical storm strength in the next day or two.
The Joint Typhoon Warning Center forecast brings the depression to southern Vietnam for a landfall sometime on Nov. 6.

Quantum entanglement, a perplexing phenomenon of quantum mechanics that Albert Einstein once referred to as “spooky action at a distance,” could be even spookier than Einstein perceived.
Physicists at the University of Washington and Stony Brook University in New York believe the phenomenon might be intrinsically linked with wormholes, hypothetical features of space-time that in popular science fiction can provide a much-faster-than-light shortcut from one part of the universe to another.
But here’s the catch: One couldn’t actually ...
A star is formed when a large cloud of gas and dust condenses and eventually becomes so dense that it collapses into a ball of gas, where the pressure heats the matter, creating a glowing gas ball – a star is born.
New research from the Niels Bohr Institute, among others, shows that a young, newly formed star in the Milky Way had such an explosive growth, that it was initially about 100 times brighter than it is now. The results are published in the scientific journal, Astrophysical Journal Letters.
The young ...
EPFL scientists have shown how to achieve a dramatic increase in the capacity of optical fibers; Their simple, innovative solution reduces the amount of space required between the pulses of light that transport data
Optical fibers carry data in the form of pulses of light over distances of thousands of miles at amazing speeds. They are one of the glories of modern telecommunications technology.
However, their capacity is limited, because the pulses of light need to be lined up one after the other in ...
NASA's Hurricane and Severe Storms Sentinel airborne mission known as HS3 wrapped up for the 2013 Atlantic Ocean hurricane season at the end of September, and had several highlights. HS3 will return to NASA’s Wallops Flight Facility in Wallops Island, Va., for the 2014 Atlantic hurricane season.
During the 2013 mission, two unmanned Global Hawks flew from Wallops for the first time. The mission highlights included studying the Saharan Air Layer, following the genesis of a tropical storm, finding a unique hybrid core or center circulation in a redeveloped storm, obtaining measurements on the strongest side of ...
Nanosponges that soak up a dangerous pore-forming toxin produced by MRSA (methicillin-resistant Staphylococcus aureus) could serve as a safe and effective vaccine against this toxin.
This "nanosponge vaccine" enabled the immune systems of mice to block the adverse effects of the alpha-haemolysin toxin from MRSA—both within the bloodstream and on the skin. Nanoengineers from the University of California, San Diego described the safety and efficacy of this nanosponge vaccine in the December 1 issue of ...
