NOAA's GOES East satellite provided an image of Potential Tropical Cyclone 10 as it continued moving north along the U.S. East Coast.

The system is still not a tropical cyclone and the chances for the system to become a tropical cyclone appear to be decreasing. Regardless, National Hurricane Center noted that tropical-storm-force winds and heavy rains are expected over portions of North Carolina later today, Aug. 29.

A Tropical Storm Warning was in effect from north of Surf City to Duck, North Carolina and for the Albemarle Sound and Pamlico Sound.

Just after Tropical Storm Pakhar made landfall in southeastern China and NASA-NOAA's Suomi NPP satellite captured an image of the storm.

When commercial airplanes break through the clouds to reach cruising altitude, they have typically arrived in the stratosphere, the second layer of Earth’s atmosphere. The air up there is dry and clear, and much calmer than the turbulent atmosphere we experience on the ground.

And yet, for all its seeming tranquility, the stratosphere can be a powerful conveyor belt, pulling air up from the Earth’s equatorial region and pushing it back down toward the poles in a continuously circulating pattern. The strength of this circulation can significantly impact the amount of water vapor, chemicals, and ozone transported around the planet.

Pines in Canada and Much of U.S. at Risk.

A study published Aug. 28, 2017, in the Proceedings of the National Academy of Sciencesadds a new dimension to the controversial decision to inject large amounts of chemical dispersants immediately above the crippled oil well at the seafloor during the Deepwater Horizon disaster in 2010. The dispersants likely reduced the amount of harmful gases in the air at the sea surface—diminishing health risks for emergency responders and allowing them to keep working to stop the uncontrolled spill and clean up the spilled oil sooner.

On Monday, Aug. 28 at 7 a.m. CDT the National Hurricane Center said the center of Harvey is emerging into the Gulf of Mexico. A NASA animation of imagery from NOAA's GOES East satellite shows Harvey as it lingered over southeastern Texas over the weekend of Aug. 26 and 27 and moving back toward the Gulf of Mexico on Aug. 28.

The National Hurricane Center noted "life-threatening flooding continues over southeastern Texas." NHC stressed that people should never attempt to travel into flooded roadways.

The full damage wreaked by Hurricane Harvey won’t be totaled up for days if not weeks, but thankfully the destruction so far has resulted in relatively few fatalities. The impact on energy infrastructure, though, is a different story. The storm hit southeast Texas, a major hub of the U.S. petroleum and natural gas industries. It stands as further evidence that the centralized model for fuel production and transportation is out-of-date, leaving the U.S. exposed to economic disruption and threats to national security. In the age of climate change, a more nimble and flexible approach is needed.

On Friday, August 25, U.S. Coast Guard Cutter Healy will sail from Dutch Harbor, Alaska, with a team of NOAA scientists and collaborators on a 22-day cruise to study environmental change in the western Arctic Ocean.

Scientists will track ecosystem responses to rapidly changing environmental conditions such as sea ice decline, ocean acidification and rising air and water temperature, as the ship travels north through the Bering, Chukchi and Beaufort seas.

Storm-tide sensors are being installed at key locations along the Texas Gulf Coast by the U.S. Geological Survey in advance of Hurricane Harvey.

Storm surge, coastal erosion and inland flooding are among the most dangerous natural hazards unleashed by hurricanes, with the capacity to destroy homes and businesses, wipe out roads, bridges, water and sewer systems, and profoundly alter landscapes. The USGS has experts on these hazards, state-of-the-science computer models for forecasting them, and sophisticated equipment for monitoring actual flood and tide conditions.

In 2011 a team of researchers led by Vasilii Petrenko, an assistant professor of Earth and environmental sciences at the University of Rochester, spent seven weeks in Antarctica collecting and studying 2,000-pound samples of glacial ice cores that date back nearly 12,000 years. The ancient air trapped within the ice revealed surprising new data about methane that may help inform today’s policymakers as they consider ways to reduce global warming.
