NASA eyes power in Tropical Storm Washi, warnings in the Philippines

16.12.2011
NASA's TRMM satellite measured heavy rainfall and powerful towering thunderstorms as Tropical Depression 27W intensified into Tropical Storm Washi today. Now, warnings are up in areas of the Philippines as Washi heads in that direction.

Now that Tropical Depression 27W strengthened into a tropical storm, it has been given two names: Washi and Sendong. Tropical cyclones within each ocean basin are named in six year lists, but some countries will also assign their own names to a storm, so following a storm can get a little confusing.


TRMM provided a "top down" rainfall analysis of Tropical Storm Washi on Dec. 15. Light to moderate rainfall (green and blue) was falling throughout the storm a rate between .78 to 1.57 inches/20 to 40 mm per hour). There was a small area of heavy (red) rainfall to the southwest of the center. Credit: SSAI/NASA, Hal Pierce

Low pressure areas that form into a depression are given a number and Washi's was 27W, for the twenty-seventh tropical depression in the western North Pacific this season. Once it strengthens into a tropical storm it gets a name.

Tropical Storm Washi, or Sendong as it is known in the Philippines has residents there on guard as it continues to strengthen upon its approach.

The Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) Weather Forecasting Section, Weather Division is responsible for forecasts of tropical cyclones affecting the Philippines. PAGASA noted in a bulletin today, December 15 at 5 p.m. local time (0900 UTC or 4 a.m. EST): "Tropical Storm 27W (called "Sendong" in the Philippines) is expected to make landfall over Surigao del Sur early tomorrow (Friday) afternoon and by Saturday afternoon, at 220 km East Northeast of Puerto Princesa City. By Sunday afternoon, it will be at 260 km West Northwest of Puerto Princesa City."

As a result of Washi's (Sendong) approach, PAGASA has posted warning signals. Signal One is in effect for Mindanao and Visayas. Mindanao is the second largest and easternmost island of the Philippines. It is one of the three island groups in the country, the others being Luzon and the Visayas.

Included in the warning in Mindanao is the province of Surigao Del Norte including Siargao Island, Surigao Del, Sur and Dinagat Province, Agusan Provinces and Misamis Oriental. Included in the warning in Visayas are the provinces of Eastern Samar and Western Samar, Leyte Provinces, Camotes Island, and Bohol. Heavy rains and gusty winds are expected. Rainfall may cause flooding and mudslides.

On Dec. 15 at 0900 UTC, Tropical Storm Washi had maximum sustained winds near 35 knots (40 mph/65 kmh). It was about 140 nautical miles (161 miles/259 km) west of Palau near 7.7 North and 131.5 East. It was moving quickly to the west at 20 knots (23 mph/37 kmh).

When the Tropical Rainfall Measuring Mission (TRMM) satellite passed over Washi early today, Dec. 15 at 0205 UTC (Dec. 14 at 9:05 a.m. EST) a "hot towering" thunderstorm was seen in the southwestern quadrant of the storm topping 10 miles (16 kilometers) high. Research done at NASA's Goddard Space Flight Center in Greenbelt, Md. has shown that tropical cyclones are likely to intensify within six hours of a "hot tower" being spotted in a tropical cyclone.

Multispectral satellite imagery showed the banding of thunderstorms wrapping into the center of circulation - another indication that the storm is strengthening. The storm is strengthening because the wind shear is light (only 10 knots/11 mph/18 kmh) and the sea surface temperatures are very warm at about 88 degrees Fahrenheit (31 Celsius) which is about 8F warmer than the minimum temperature needed to maintain a tropical cyclone.

The Joint Typhoon Warning Center expects Washi to make landfall on Friday, Dec. 16 and then re-emerge over water in the Sulu Sea. In the meantime, residents of Minandao and Visayas need to prepare for Washi's arrival.

Im Focus: Can the immune system be boosted against Staphylococcus aureus by delivery of messenger RNA?

Staphylococcus aureus is a feared pathogen (MRSA, multi-resistant S. aureus) due to frequent resistances against many antibiotics, especially in hospital infections. Researchers at the Paul-Ehrlich-Institut have identified immunological processes that prevent a successful immune response directed against the pathogenic agent. The delivery of bacterial proteins with RNA adjuvant or messenger RNA (mRNA) into immune cells allows the re-direction of the immune response towards an active defense against S. aureus. This could be of significant importance for the development of an effective vaccine. PLOS Pathogens has published these research results online on 25 May 2017.

Staphylococcus aureus (S. aureus) is a bacterium that colonizes by far more than half of the skin and the mucosa of adults, usually without causing infections....

Im Focus: A quantum walk of photons

Physicists from the University of Würzburg are capable of generating identical looking single light particles at the push of a button. Two new studies now demonstrate the potential this method holds.

Im Focus: Turmoil in sluggish electrons’ existence

An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.

We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...

Im Focus: Wafer-thin Magnetic Materials Developed for Future Quantum Technologies

Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.

Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...
