Tropical Storm Hernan degenerated into a remnant low pressure area on July 29. Infrared imagery from NASA's Aqua satellite revealed cloud tops were warming as the storm weakened.
The Atmospheric Infrared Sounder or AIRS instrument aboard Aqua gathered infrared data on a quickly weakening Hernan on July 29 at 5:11 a.m. EDT.
The data was then made into a false-colored image at NASA's Jet Propulsion Laboratory in Pasadena, California. The AIRS image showed small, fragmented areas of a few powerful thunderstorms with high, cold cloud tops in Tropical Storm Hernan as it continued weakening.
For the most part, however, the cloud top temperatures warmed through the system which indicated the uplift was weaker.
By 11 a.m. EDT (1500 UTC) Hernan was no longer a tropical cyclone and had become a remnant low pressure area. The center of post-tropical cyclone Hernan was located near latitude 23.5 north and longitude 121.1 west, about 710 miles (1,145 km) west of the southern tip of Baja California, Mexico.
The post-tropical cyclone is moving toward the west-northwest near 15 mph (24 kph) and this general heading with a decrease in forward speed is expected through Wednesday night, July 30. Maximum sustained winds are near 35 mph (55 kph).
The National Hurricane Center expects that remnant low to dissipate during the next couple of days.

Physicists have developed a new technique that uses electrical voltages to control the electron spin on a chip. The newly-developed method provides protection from spin decay, meaning that the contained information can be maintained and transmitted over comparatively large distances, as has been demonstrated by a team from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute. The results have been published in Physical Review X.
For several years, researchers have been trying to use the spin of an electron to store and transmit information. The spin of each electron is always coupled...
What is the mass of a proton? Scientists from Germany and Japan successfully did an important step towards the most exact knowledge of this fundamental constant. By means of precision measurements on a single proton, they could improve the precision by a factor of three and also correct the existing value.
To determine the mass of a single proton still more accurate – a group of physicists led by Klaus Blaum and Sven Sturm of the Max Planck Institute for Nuclear...
