Later in the day at 1700 UTC (1 p.m. EDT) on July 8, the Moderate Resolution Imaging Spectroradiometer or MODIS instrument that flies aboard NASA's Aqua satellite captured a visible image of Tropical Storm Chantal. The image showed the Chantal continued to organize as it moves through the Caribbean Sea. Tropical storm force winds extend outward up to 90 miles (150 km) mainly to the north of the center, but the extent of the cloud cover appears larger in visible imagery.
NASA's TRMM satellite showed that the most intense rain falling in Tropical Storm Chantal on July 8 was falling at a rate of over 115.5 mm/hr. (~4.5 inches) near Chantal's center of circulation.

As of 8 a.m. EDT on July 9, a tropical storm warning was in effect for: Barbados, Dominica, St Lucia, Martinique, Guadeloupe, Puerto Rico and southern coast of the Dominican Republic from Cabo Engano to the border with Haiti. In addition, a tropical storm watch was in effect for the U.S. Virgin Islands, Saint Vincent, Vieques and Culebra, Haiti, the northern coast of the Dominican Republic, Turks and Caicos and the southeastern Bahamas.
The National Hurricane Center (NHC) noted that a storm surge of 1 to 3 feet above normal tidal levels can be expected in the Windward and Leeward Islands and Puerto Rico. Along the southern coast of the Dominican Republic, the surge is expected to be higher, reaching 2 to 4 feet. The heavy rainfall that NASA's TRMM satellite observed can be expected over the Leeward and Windward Islands, with totals between 2 to 4 inches, and isolated totals to 6 inches.
NHC expects tropical storm conditions are expected to affect portions of Windward Islands today, July 9, and Puerto Rico tonight or early Wednesday.
At 8 a.m. EDT Chantal's maximum sustained winds were near 50 mph (85 kph). NHC expects some strengthening. Chantal was centered near 13.8 north latitude and 59.7 west longitude, just 45 miles (70 km) north-northwest of Barbados, and 85 miles east of St. Lucia. Chantal was moving to the west-northwest at a speedy 26 mph (43 kph), and is expected to continue in that general direction for the next couple of days. Minimum central pressure is near 1010 millibars.
Chantal's center is expected to move into the eastern Caribbean Sea during the afternoon and evening of July 9 and near the Dominican Republic by July 10. Current forecast tracks from the NHC bring Chantal along the eastern coast of Florida by the weekend of July 13 and 14.

A new manufacturing technique uses a process similar to newspaper printing to form smoother and more flexible metals for making ultrafast electronic devices.
The low-cost process, developed by Purdue University researchers, combines tools already used in industry for manufacturing metals on a large scale, but uses...
For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.
To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...
For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.
Whirlpools are an everyday experience in a bath tub: When the water is drained a circular vortex is formed. Typically, such whirls are rather stable. Similar...
Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.
A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...
Optical spectroscopy allows investigating the energy structure and dynamic properties of complex quantum systems. Researchers from the University of Würzburg present two new approaches of coherent two-dimensional spectroscopy.
"Put an excitation into the system and observe how it evolves." According to physicist Professor Tobias Brixner, this is the credo of optical spectroscopy....
