NASA research indicates that whenever a hot tower is spotted, a tropical cyclone will likely intensify. Less than 14 hours after the TRMM satellite captured an image of Ileana's rainfall and cloud heights, Ileana strengthened into a hurricane on Aug. 29.
NASA's TRMM satellite captured a view of Ileana's rainfall rates on Aug. 29 at 2:17 a.m. EDT. The purple areas indicated the heaviest rainfall rates, near 70 mm (2.7 inches) per hour.

NASA's Tropical Rainfall Measuring Mission (TRMM) satellite captured a view of Ileana's rainfall rates on Aug. 29 at 2:17 a.m. EDT and saw the heaviest rainfall rates, near 50 mm (2.0 inches) per hour in a band of thunderstorms southeast of the center of circulation. TRMM identified some hot towering clouds around the center of circulation that were higher than 9.3 miles (15 km).
On Aug. 30, satellite data showed a ragged double eyewall in the center of circulation. On Aug. 30 at 11 a.m. EDT, Hurricane Ileana's maximum sustained winds had increased to near 80 mph (130 kmh). Hurricane force winds extend outward up to 25 miles (35 km) from the center, which makes Ileana's hurricane-force wind area about 15 miles larger than Hurricane Kirk's in the Atlantic Ocean today. Ileana's tropical storm force winds extend outward up to 90 miles (150 km).The National Hurricane Center expects that Ileana won't strengthen much more before weakening on Aug. 31.
Ileana's center was about 305 miles (495 km) southwest of the southern tip of Baja California, Mexico, near latitude 20.2 north and longitude 113.7 west. Ileana is moving toward the northwest near 8 mph (13 kmh) and into cooler waters that will sap her strength.
The National Hurricane Center expects Ileana to weaken to a remnant low pressure area over the weekend of Sept. 1-2, while drifting west, and away from land.Text credit: Rob Gutro

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...
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...
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...
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...
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...
