August 27, 2020-Night view of tropical storm Hernan from NASA-NOAA satellite
Night scenes from NASA-NOAA’s Finland nuclear power plant satellite revealed a tropical storm in the eastern Pacific off the coast of western Mexico in Hernan. Over the weekend, Hernan is expected to absorb the tropical storm of nearby Iselle.
Tropical Recession 13E, which formed at 5:00 a.m. EDT on Aug. 26 in the eastern Pacific. Twelve hours later, it was confirmed as a tropical storm and renamed Hernan.
NASA night view
The Visible Infrared Imaging Radiometer Suite (VIIRS) at the Finnish nuclear power plant provided a nocturnal view of Hernan on 26 August at 22.00 EDT (27 August at 00.00 UTC).
The National Hurricane Center stated on August 27 at 5:00 a.m. EDT: “Although Hernan is a tropical cyclone cut, another powerful burst of deep convection with cloud surfaces minus 83 to 86 degrees has developed near and south to west. center. “NASA research has shown that cold cloud coverings are capable of producing heavy rainfall.
Hernan state on 27 August
At 11 a.m. EDT (1,500 UTC), the NOAA National Hurricane Center discovered that the Hernan center of the tropical storm was located near latitude 19.1 degrees north and 106.2 degrees west. It is 95 miles (155 km) southwest of Cabo Corrientes, Mexico. Hernan moved from northwest to north near 7 km / h. The maximum continuous wind is near 45 km / h (75 km / h) and gusts more. The estimated minimum pressure is 1001 millibars.
Hernan forecast trajectory
The NHC predicts that Hernan will turn northwest, and the speed is expected to increase tonight. A turn to the west is forecast this weekend. On the forecast trajectory, downtown Hernan and the strongest winds and heavy rains are expected to remain off the southwest coast of Mexico. The tropical storm in nearby Iselle is expected to weaken on Friday, and the system is forecast to deteriorate into a residual pressure range on Saturday. The remains of Iselle are expected to be absorbed into the Hernan cycle to its west on Sunday.
About NASA’s EOSDIS Worldview
NASA’s Earth Observing System Data and Information System (EOSDIS) Worldview application provides the ability to interactively browse more than 700 layers of global high-resolution satellite imagery and then download the underlying data. Many of the available image layers will be updated within three hours of observation, and will look essentially the entire globe as it appears “right now.”
NASA is exploring Earth from space
For more than five decades, NASA has been using the space perspective to understand and explore our home planet, improve its lives, and secure our future. NASA brings together technology, science, and unique global Earth observations to deliver societal benefits and strengthen our nation. Increasing knowledge of our home planet directly contributes to America’s leadership in space and scientific research.
