Tropical Storm Douglas is on a weakening trend, according to the National Hurricane Center, and satellite imagery showed that the storm appeared more elongated on July 3.
NOAA's Geostationary Operational Environmental Satellite or GOES-West satellite captured visible data on Douglas just after sunrise on July 3 at 13:15 UTC (9:15 a.m. EDT).
The data from GOES-West was made into an image at NASA/NOAA's GOES Project at the NASA Goddard Space Flight Center in Greenbelt, Md.
Forecaster Stewart at the National Hurricane Center cited that Douglas' thunderstorm activity had been gradually waning during the early morning hours on July 3 and infrared data, such as that from the Atmospheric Infrared Sounder instrument aboard NASA's Aqua satellite showed that cloud tops were warming, which indicates cloud heights were falling and the uplift of air in the storm was weakening.
Despite that, microwave satellite data from NOAA's AMSU instrument and NASA's Tropical Rainfall Measuring Mission satellite indicated that Douglas had maintained a tight low-level circulation including a shallow eye-like feature.
On July 3 at 5 a.m. EDT (9:00 UTC), Douglas' maximum sustained winds were near 40 mph (65 kph) and the storm was weakening.
The center of Douglas was located near latitude 20.4 north and longitude 116.5 west, about 455 miles (735 km) west-southwest of the southern tip of Baja California, Mexico. Douglas is moving toward the northwest near 3 mph (6 kph).
The NHC expects Douglas to become a tropical depression late on July 3 and degenerate into a remnant low pressure area by the fourth of July.

In the last decades, sea level has been rising continuously – about 3.3 mm per year. For reef islands such as the Maldives or the Marshall Islands a sinister picture is being painted evoking the demise of the island states and their cultures. Are the effects of sea-level rise already noticeable on reef islands? Scientists from the ZMT have now answered this question for the Takuu Atoll, a group of Pacific islands, located northeast of Papua New Guinea.

The ‘Internet of Things’ is growing rapidly. Mobile phones, washing machines and the milk bottle in the fridge: the idea is that minicomputers connected to these will be able to process information, receive and send data. This requires electrical power. Transistors that are capable of switching information with a single electron use far less power than field effect transistors that are commonly used in computers. However, these innovative electronic switches do not yet work at room temperature. Scientists working on the new EU research project ‘Ions4Set’ intend to change this. The program will be launched on February 1. It is coordinated by the Helmholtz-Zentrum Dresden-Rossendorf (HZDR).
