Tropical Storm Guillermo continued to creep closer to the Hawaiian Islands on Aug. 4, and NOAA's GOES-West satellite captured an image of the weakening storm. Westerly wind shear is pushing a stream of clouds to the northeast of the center, making it appears as if Guillermo has a long tail stretching back toward Mexico.
Guillermo is getting so close, in fact, that a tropical storm watch is in now in effect for Hawaii county and Maui County, including the islands of Maui, Molokai, Lanai and Kahoolawe. A tropical storm watch means that tropical storm conditions are possible within the watch area, in this case within 36 to 48 hours.
An infrared image of Tropical Storm Guillermo was taken from NOAA's GOES-West satellite on Aug. 4 at 1200 UTC (8 a.m. EDT) as it neared Hawaii. NOAA manages the GOES series of satellites and the NASA/NOAA GOES Project at NASA's Goddard Space Flight Center in Greenbelt, Maryland creates images and animations of the GOES satellite data. The image showed that Guillermo appears more elongated, and appears to have developed a "tail." The tail is actually a stream of clouds being pushed to the northeast of the storm from westerly winds.
At 11 a.m. EDT (5 a.m. HST/1500 UTC) on Aug. 4 the center of tropical storm Guillermo was located near latitude 19.7 north and longitude 148.5 west. Guillermo is moving toward the northwest near 12 mph (19 kph) and the storm is expected to shift to the west-northwest late on Aug. 4 through Aug. 6.
Maximum sustained winds are near 70 mph (110 kph), and little change in strength is expected on Aug. 4 with slow and steady weakening anticipated thereafter. The estimated minimum central pressure is 989 millibars.
On the forecast track, the Central Pacific Hurricane Center forecasts the center of Guillermo is expected to pass 215 miles northeast of Hilo Wednesday afternoon, Aug. 5 and around 165 miles north of Maui Wednesday night.
So what can the Hawaiian Islands expect from Guillermo as it passes by?
The National Hurricane Center noted that tropical storm conditions are possible on the big island of Hawaii and the islands of Maui, Molokai, Lanai and Kahoolawe in Maui County on Aug. 5. Guillermo is expected to generate between 1 to 3 inches of rainfall with isolated maximum amounts near 7 inches mainly in higher terrain. In addition, rough and large surf is expected along east-facing shores of the main Hawaiian Islands through much of the week.

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....
Ultra-short, high-intensity X-ray flashes open the door to the foundations of chemical reactions. Free-electron lasers generate these kinds of pulses, but there is a catch: the pulses vary in duration and energy. An international research team has now presented a solution: Using a ring of 16 detectors and a circularly polarized laser beam, they can determine both factors with attosecond accuracy.
Free-electron lasers (FELs) generate extremely short and intense X-ray flashes. Researchers can use these flashes to resolve structures with diameters on the...
