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
GPM overpass of Hurricane Delta
The 2020 Atlantic hurricane season will go down as one of the most active seasons on record, currently second only to the incredible 2005 season in terms of the number of named storms. The 2020 season is only the second time in recorded history (the other being 2005) that the Greek alphabet has been used because the number of named storms has exceeded the number of regular names on the list. Another interesting aspect of the 2020 season has been the number of storms that have struck the northern Gulf Coast. So it is no surprise that the latest storm, Hurricane Delta, would also find its way to
IMERG Rainfall Totals from Medicane Ianos
From September 14th - 20th, 2020, NASA’s IMERG algorithm estimated the rainfall from a Mediterranean cyclone with tropical-like characteristics, commonly known as a “Medicane”, which flooded parts of Greece. Medicanes typically appear once or twice a year and are similar to tropical storms in that both have a symmetric structure, a warm core, a clearly visible eye, and winds of at least tropical-storm strength. This particular storm system, dubbed "Ianos" by the National Observatory of Athens, led to media reports of flooding throughout the islands of Kefalonia and Zakynthos off the western
IMERG totals from hurricane sally
The northern Gulf Coast has seen its share of storms this busy hurricane season. At the end of August, then Tropical Storm Marco brought heavy rains to parts of the Florida Panhandle while western Louisiana took a direct hit from the much more powerful Category 4 Hurricane Laura. Now, just over 3 weeks since Laura made landfall, the northern Gulf Coast was struck again, this time by Hurricane Sally. Though not as powerful as Laura, the still rather strong Sally behaved more like Marco. But, while Marco was largely sheared apart with most of the rain well northeast of the center as it slowed
IMERG Rainfall from Typhoons Bavi, Maysak and Haishen
From August 22 through September 7, 2020, NASA’s IMERG algorithm estimated rainfall from three typhoons as they passed over the Pacific Ocean, Japan, and Korea. According to NOAA's records, this was the only time since records have been kept starting in 1945 that the Korean peninsula saw three landfalling typhoons in a single year, let alone in two weeks. Each of the three typhoons--Bavi, Maysak, and Haishen--reached the equivalent of “major hurricane” status, meaning Category 3 or above on the Saffir-Simpson hurricane-intensity scale (shown here as a red in the hurricane track) along their
