Coastal evacuations were already happening in New York City, coastal New Jersey, Delaware, Maryland, Virginia, and North and South Carolina.

NASA satellites gathered rainfall measurements and saw heavy rain and hot towering thunderstorms around Irene's center signaling the power behind her. Even on August 25, the Tropical Rainfall Measuring Mission (TRMM) satellite saw rainfall in intense bands of thunderstorms around her eye, that were dropping rainfall at 2 inches (50 mm) per hour.
NASA's Terra satellite captured a visible image of Hurricane Irene from the Moderate Resolution Imaging Spectroradiometer (MODIS) instrument on August 26 at 12:30 p.m. EDT, when Hurricane Irene was off the Carolinas. Although no eye was visible, Irene was still a Category 2 hurricane on the Saffir-Simpson scale and it was still at that intensity at 3:10 p.m. EDT.
NOAA's GOES-13 satellite provided a much broader view of Hurricane Irene against the entire U.S. east coast on August 26, 2011 at 1:40 p.m. EDT. The extent of Irene's 600 mile wide cloud cover was obvious as it stretched over a third of the U.S. east coast.
Residents along the eastern U.S. coast are facing hurricane-force winds and inland areas are facing tropical storm-force winds. At 2 p.m. EDT on August 26, tropical storm force winds have already arrived along the coast of the Carolinas. Hurricane Irene's center was located about 300 miles south-southwest of Cape Hatteras, North Carolina, near 31.2 North and 77.5 West. Its maximum sustained winds were near 100 mph and it was moving to the north near 14 mph. Minimum central pressure was 951 millibars.
Residents along the east coast need to heed watches and warnings and evacuations. Rainfall is a serious issue with Irene as she is expected to drop 6 to 10 inches with isolated amounts of 15 inches from eastern North Carolina into southeastern Virginia, eastern Maryland, Delaware, eastern Pennsylvania, New Jersey, southeastern New York, Long Island, Western Connecticut, and western Massachusetts through Monday morning.
The NHC said that dangerous storm surge levels as much as 11 feet are possible in the warning area in North Carolina, and up to 8 feet in southern portions of the Chesapeake Bay. The New Jersey shore can expect surges up to 6 feet above ground level.

An international team of scientists has proposed a new multi-disciplinary approach in which an array of new technologies will allow us to map biodiversity and the risks that wildlife is facing at the scale of whole landscapes. The findings are published in Nature Ecology and Evolution. This international research is led by the Kunming Institute of Zoology from China, University of East Anglia, University of Leicester and the Leibniz Institute for Zoo and Wildlife Research.
Using a combination of satellite and ground data, the team proposes that it is now possible to map biodiversity with an accuracy that has not been previously...
Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.
Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...
Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.
As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...
Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.
With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...
