GPM Overpass of Hurricane Eta Nov. 11 2020
After a long and meandering journey over Central America, across central Cuba, and through the Florida Keys, Eta, the 28th named storm and 12th hurricane of the 2020 Atlantic hurricane season, wound up nearly stationary as a moderate tropical storm in the southeastern Gulf of Mexico just north of the western tip of Cuba on the morning of November 10th. Before long however, a deep layer trough located over the western third of the US began to shift eastward, and by the afternoon of the 10th, it started to pull Eta back towards the north and the west coast of the Florida peninsula. As it did so
Hurricane Eta over Florida
After striking the northeast coast of Nicaragua as a powerful Category 4 storm back on November 3, Hurricane Eta weakened rapidly over Central America but still brought major flooding and triggered numerous landslides that so far have resulted in at least 250 fatalities across the region, according to media reports. Eta was down to a tropical depression when the center re-emerged over the northwestern Caribbean on the evening of November 5. An upper-level trough over the Gulf of Mexico first steered Eta northeastward towards Cuba on the 6th. Because it was disorganized after its trek across

The extremely active 2020 Atlantic hurricane season, aided by the ongoing La Niña, continues on. After Hurricane Zeta made landfall along the northern part of the Gulf Coast, yet another hurricane has arisen - Hurricane Eta, the strongest of the season. Like Zeta, Eta also formed in the Caribbean, where sea surface temperatures are still running quite warm at around 29° C, almost a full degree above average and well above the typical 26° C needed for tropical cyclone development. But while Zeta turned north into the Gulf of Mexico, Eta moved westward where it delivered powerful winds and

The Global Precipitation Measurement (GPM) Core Observatory satellite flew over Hurricane Eta at 11:41 p.m. CT on Tuesday, Nov. 3 (0541 UTC Wednesday, Nov. 4). GPM observed the storm’s rainfall with its two unique science instruments: the GPM Microwave Imager ( GMI ) and Dual-frequency Precipitation Radar ( DPR ). As the visualization shows, the instruments observed a large swath of heavy precipitation extending to the north and east of the hurricane’s center, which matched earlier forecasts that called for particularly heavy rainfall across the storm’s path. These two- and three-dimensional
GPM Overpass of Hurricane Zeta on 10/28/20
As Hurricane Zeta moves towards landfall on the U.S. Gulf Coast, NASA has eyes on the storm with an array of Earth-observing instruments and stands ready to aid affected communities with critical data and analysis. Zeta is following a path similar to Hurricane Delta, which after crossing the Yucatan Peninsula made its way across the Gulf of Mexico and struck the Louisiana coast as a Category 2 hurricane on October 9. If Zeta makes landfall as expected along the northern Gulf Coast, it will become the 7th named storm to do so in this record-breaking season, following Tropical Storm Cristobal
