Preliminary reports recommend it is the fifth-strongest storm ever to make landfall in the continental U.S.
Exactly 16 years after Katrina made landfall, another significant typhoon blew into southernLouisiana Around midday on August 29, 2021, Hurricane Ida came ashore at Port Fourchon with continual winds of 150 miles (240 kilometers) per hour and a main pressure of 930 millibars. Preliminary reports recommend it is the 5th greatest typhoon (based upon wind speed) ever to make landfall in the continental U.S.
At 2: 50 a.m. Central Daylight Time on August 30, the Visible Infrared Imaging Radiometer Suite (VIIRS) on the Suomi NPP satellite obtained a nighttime view (above) of HurricaneIda On the early morning of August 29, the NOAA GOES-16 satellite acquired data for an animation of the enormous eyewall approaching the coast.
In the last 24 hours prior to landfall, the storm’s main pressure dropped from 985 millibars to 929, and winds magnified quickly from 85 to 150 miles per hour. According to the National Hurricane Center, a storm has actually gone through “rapid intensification” when winds increase by a minimum of 35 miles per hour within 24 hours. The accumulation was partially sustained by the hot summer season surface area waters of the Gulf of Mexico, which had to do with 30–31 ° Celsius (86–88 ° Fahrenheit).

The animation above reveals the development of Ida’s wind field in between August 27–30,2021 The greatest winds appear intense yellow to white; more moderate winds (still gale-force) are tones of orange and intense purple. Atmospheric information have actually been gone through the Goddard Earth Observing System Model -5 (GEOS-5), an information assimilation design that researchers at NASA utilize to evaluate worldwide weather condition phenomena. The GEOS design consumes wind information from more than 30 sources, consisting of ships, buoys, radiosondes, dropsondes, airplane, and satellites. The design output is spaced out on a 0.25 to 0.3 degree grid, so it does not always record peak gusts and extremes as determined by private instruments on the surface area.
“For me, the most compelling aspect of Ida was its rapid intensification up to landfall,” stated Scott Braun, a researcher who focuses on cyclones at NASA’s Goddard Space FlightCenter “The storm was very similar to Hurricane Opal and Hurricane Katrina in that they underwent rapid intensification over a region, or eddy, of deep warm water known as the Gulf Loop Current. In addition to providing warm water for fuel, such eddies impede the mixing of colder water to the surface. Such cooling would typically lead to storm weakening, or at least an end to strengthening. Both Opal and Katrina weakened before landfall, mitigating the impacts of the storms to some extent, even though they were obviously still bad. In Ida, near-coast weakening did not really occur.”
The typhoon pressed a wall of water– a storm rise– onto the coast of Louisiana andMississippi Weather stations and media reports kept in mind rises varying from 3 to 9 feet (1 to 3 meters) in locations like Grande Isle, Shell Beach, Lafitte, Barataria, Port Fourchon, and BayWaveland Port Fourchon is a significant business and commercial center for the United States, especially for oil and gas.

The storm stuck around over southern Louisiana for the majority of August 29, dropping flood-provoking rains prior to moving north and east into Mississippi and Alabama on August30 The sluggish rate of the storm might have enhanced the severe damage to electrical power and drinking water facilities, while postponing the start of clean-up. More than 1 million clients (services, families) in Louisiana had actually supposedly lost power by midday on August30 Another 100,000 clients lost electrical energy in Mississippi and 12,000 inAlabama The map above reveals the circulation of power interruptions as assembled by Power Outage.US from openly available information sources.
“I was interested in Ida’s translational speed after landfall,” stated Hui Su, who studies cyclones at NASA’s Jet PropulsionLaboratory “There have been studies that have talked about how global warming causes the slowing down of tropical cyclones, which can contribute to greater flooding and inundation damages. (For example, hurricanes Harvey and Dorian.) There are still debates because of the quality of historical data, but climate model simulations show that the translational speed of hurricanes would decrease with global warming.”
