The Eastern Pacific Ocean has been warm this springtime, and those warmer waters have contributed to the development of storms like Tropical Storm Julio and Hurricane Iselle.
"Ocean temperatures in the Eastern Tropical Pacific were heated up because of the strong Kelvin wave activity this spring. Although the initial excitement of an impending El Nino has quieted down, these warmer waters have caused an early and active hurricane season," said Bill Patzert, Climatologist at NASA's Jet Propulsion Laboratory in Pasadena, California.
"Kelvin waves" are massive ripples in sea level that travel across the Pacific from Australia to South America. Forecasters are paying close attention because these waves could be a herald of El Niño.
"Today, two strong cyclonic systems, Iselle (a major category 4 hurricane) and weaker Julio have their sights set on the Hawaiian Islands," Patzert said. "Hawaii is on high alert. Hurricane impacts in the Hawaiian Islands are quite unusual. Since 1950, only five hurricanes have made land-fall in the Islands. The good news is that both Iselle and Julio should weaken as they enter cooler ocean waters."
On August 5, NOAA's GOES-West satellite captured an image of Tropical Storm Julio and developing System 98E located near southern Mexico's coast.
On August 5 at 11 a.m. EDT (1500 UTC) Tropical Storm Julio had maximum sustained winds near 60 mph (95 kph). The National Hurricane Center (NHC) expects Julio to become a hurricane tomorrow, Wednesday, August 6.
Julio was centered about 1,145 miles (1,845 km) west-southwest of the southern tip of Baja California, near latitude 14.0 north and longitude 124.7 west. Julio is moving toward the west near 13 mph (20 kph). NHC expects a general westward to west-northwestward motion to continue through Thursday.
To the east of Tropical Storm Julio is yet another developing area of low pressure. That area, designated as System 98E is located near 10.3 north latitude and 98.1 west longitude several hundred miles south of Acapulco, Mexico. It has a medium chance of developing into a tropical depression in the next two days.

Many joining and cutting processes are possible only with lasers. New technologies make it possible to manufacture metal components with hollow structures that are significantly lighter and yet just as stable as solid components. In addition, lasers can be used to combine various lightweight construction materials and steels with each other. The Fraunhofer Institute for Laser Technology ILT in Aachen is presenting a range of such solutions at the LASER World of Photonics trade fair from June 22 to 25, 2015 in Munich, Germany, (Hall A3, Stand 121).
Lightweight construction materials are popular: aluminum is used in the bodywork of cars, for example, and aircraft fuselages already consist in large part of...
Using ultrashort laser pulses, scientists in Max Planck Institute of Quantum Optics have demonstrated the emission of extreme ultraviolet radiation from thin dielectric films and have investigated the underlying mechanisms.
In 1961, only shortly after the invention of the first laser, scientists exposed silicon dioxide crystals (also known as quartz) to an intense ruby laser to...
The only professorship in Germany to date, one master's programme, one laboratory with worldwide unique equipment and the corresponding research results: The University of Würzburg is leading in the field of biofabrication.
Paul Dalton is presently the only professor of biofabrication in Germany. About a year ago, the Australian researcher relocated to the Würzburg department for...
Physicists have developed an innovative method that could enable the efficient use of nanocomponents in electronic circuits. To achieve this, they have developed a layout in which a nanocomponent is connected to two electrical conductors, which uncouple the electrical signal in a highly efficient manner. The scientists at the Department of Physics and the Swiss Nanoscience Institute at the University of Basel have published their results in the scientific journal “Nature Communications” together with their colleagues from ETH Zurich.
Electronic components are becoming smaller and smaller. Components measuring just a few nanometers – the size of around ten atoms – are already being produced...
