NASA Sees Intensifying Hurricane Carlotta Threatening Mexico

18.06.2012
NASA's Tropical Rainfall Measuring Mission (TRMM) satellite flew over Carlotta when it was a tropical storm and found areas of heavy rain throughout and powerful high thunderstorms almost 10 miles high, hinting the storm would strengthen into a hurricane. By 8 a.m. EDT on June 15, Carlotta became the first hurricane of the eastern Pacific Ocean season.

As Carlotta neared the western coast of Mexico, warnings and watches were posted. On Friday, June 15, 2012, a hurricane warning was in effect for the Pacific Coast of Mexico from Salina Cruz to Acapulco. A hurricane watch is in effect for the Pacific Coast of Mexico east of Salina Cruz to Barra De Tonala, and west of Acapulco to Tecpan De Galeana.

A 3-D perspective image was created at NASA's Goddard Space Flight Center in Greenbelt, Md. by Hal Pierce of SSAI, who works on the TRMM mission team. Hal noted that the TRMM Precipitation Radar shows there were several powerful thunderstorms taller than 15km (~9.3 miles). The tallest convective thunderstorm towers, reaching above 16km (~9.9 miles), were seen on the northwestern side of the developing tropical cyclone. Those convective towers or "hot towers" usually indicate strengthening within 6 hours, and Carlotta did, indeed, become a hurricane.

TRMM imagery also showed that the storm was getting better organized with several areas of heavy rainfall located in forming convective rain bands.

At 11 a.m. EDT (8 a.m. PDT) Hurricane Carlotta's maximum sustained winds were near 80 mph making it officially the first hurricane of the Eastern Pacific Ocean hurricane season.

Carlotta was located about 120 miles (195 km) south-southeast of Puerto Angel and 330 miles (530 km) southeast of Acapulco, Mexico. Because tropical-storm-force winds extend out 50 miles (85 kilometer) from Carlotta's center, Puerto Angel was not yet experiencing them at 11 a.m. EDT (8 a.m. PDT), but that will change as Carlotta draws ever closer.

Carlotta's center was near latitude 14.0 north and longitude 96.0 west. Carlotta was moving to the northwest near 12 mph (19 kph) and is expected to continue in that direction over the next 24 hours before turning to the west-northwest and back to sea.

As Carlotta nears the coast, rainfall poses one of the biggest threats. Heavy rains resulting in flooding and landslides are then possible as Carlotta interacts with rugged terrain near the southwestern coast of Mexico. The National Hurricane Center has forecast accumulations of 3 to 5 inches (75 to 125 mm) with isolated maximum amounts of 12 inches (300 mm) over the Mexican states of Guerrero, Oaxaca and Chiapas. Storm surge and hurricane-force winds are also expected.

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...
