Text description of the the list of costliest weather disasters in the U.S from 1980 through 2017 image.
The image is a table detailing information about several notable hurricanes. It consists of five columns: Event, Begin Date, End Date, Summary, CPI-Adjusted Estimated Cost (In Billions), and Deaths. Four hurricanes are listed: Katrina, Harvey, Maria, and Sandy. Each row provides specific details about the hurricane, including the category, affected areas, and consequences.
| Event | Begin Date | End Date | Summary | CPI-Adjusted Estimated Cost (in Billions) | Deaths |
|---|---|---|---|---|---|
| Hurricane Katrina August 2005 | 2005-08-25 | 2005-08-30 | Category 3 hurricane initially impacts the U.S. as a Category 1 near Miami, FL, then as a strong Category 3 along the eastern LA-western MS coastlines, resulting in severe storm surge damage (maximum surge probably exceeded 30 feet) along the LA-MS-AL coasts, wind damage, and the failure of parts of the levee system in New Orleans. Inland effects included high winds and some flooding in the states of AL, MS, FL, TN, KY, IN, OH, and GA. | $163.8 | 1,833 |
| Hurricane Harvey August 2017 | 2017-08-25 | 2017-08-31 | Category 4 hurricane made landfall near Rockport, Texas causing widespread damage. Harvey's devastation was most pronounced due to the large region of extreme rainfall producing historic flooding across Houston and surrounding areas. More than 30 inches of rainfall fell on 6.9 million people, while 1.25 million experienced over 45 inches and 11,000 had over 50 inches, based on 7-day rainfall totals ending August 31. This historic U.S. rainfall caused massive flooding that displaced over 30,000 people and damaged or destroyed over 200,000 homes and businesses. | $126.3 | 89 |
| Hurricane Maria September 2017 | 2017-09-19 | 2017-09-21 | Category 4 hurricane made landfall in southeast Puerto Rico after striking the U.S. Virgin Island of St. Croix. Maria's high winds caused widespread devastation to Puerto Rico's transportation, agriculture, communication and energy infrastructure. Extreme rainfall of up to 37 inches produced widespread flooding and mudslides across the island. The interruption to commerce and standard living conditions will be sustained for a long period, as much of Puerto Rico's infrastructure is rebuilt. Maria tied Hurricane Wilma (2005) for the most rapid intensification strengthening from tropical depression to Category 5 storm in 54 hours. Maria's landfall at Category 4 strength gives the U.S. a record three Category 4+ landfalls this year (Maria, Harvey, and Irma). A reanalysis on the number of deaths due to Maria is being conducted and will be updated in the coming months. | $90.9 | 65 |
| Hurricane Sandy October 2012 | 2012-10-30 | 2012-10-31 | Extensive damage across several northeastern states (MD, DE, NJ, NY, CT, MA, RI) due to high wind and coastal strum surge, particularly NY and NJ. Damage from wind, rain and heavy snow. | $71.5 | 159 |

Four hurricanes are listed: Katrina, Harvey, Maria, and Sandy. Each row provides specific details about the hurricane, including the category, affected areas, and consequences.
| Event | Begin Date | End Date | Summary | CPI-Adjusted Estimated Cost (in Billions) | Deaths |
|---|---|---|---|---|---|
| Hurricane Katrina August 2005 | 2005-08-25 | 2005-08-30 | Category 3 hurricane initially impacts the U.S. as a Category 1 near Miami, FL, then as a strong Category 3 along the eastern LA-western MS coastlines, resulting in severe storm surge damage (maximum surge probably exceeded 30 feet) along the LA-MS-AL coasts, wind damage, and the failure of parts of the levee system in New Orleans. Inland effects included high winds and some flooding in the states of AL, MS, FL, TN, KY, IN, OH, and GA. | $163.8 | 1,833 |
| Hurricane Harvey August 2017 | 2017-08-25 | 2017-08-31 | Category 4 hurricane made landfall near Rockport, Texas causing widespread damage. Harvey's devastation was most pronounced due to the large region of extreme rainfall producing historic flooding across Houston and surrounding areas. More than 30 inches of rainfall fell on 6.9 million people, while 1.25 million experienced over 45 inches and 11,000 had over 50 inches, based on 7-day rainfall totals ending August 31. This historic U.S. rainfall caused massive flooding that displaced over 30,000 people and damaged or destroyed over 200,000 homes and businesses. | $126.3 | 89 |
| Hurricane Maria September 2017 | 2017-09-19 | 2017-09-21 | Category 4 hurricane made landfall in southeast Puerto Rico after striking the U.S. Virgin Island of St. Croix. Maria's high winds caused widespread devastation to Puerto Rico's transportation, agriculture, communication and energy infrastructure. Extreme rainfall of up to 37 inches produced widespread flooding and mudslides across the island. The interruption to commerce and standard living conditions will be sustained for a long period, as much of Puerto Rico's infrastructure is rebuilt. Maria tied Hurricane Wilma (2005) for the most rapid intensification strengthening from tropical depression to Category 5 storm in 54 hours. Maria's landfall at Category 4 strength gives the U.S. a record three Category 4+ landfalls this year (Maria, Harvey, and Irma). A reanalysis on the number of deaths due to Maria is being conducted and will be updated in the coming months. | $90.9 | 65 |
| Hurricane Sandy October 2012 | 2012-10-30 | 2012-10-31 | Extensive damage across several northeastern states (MD, DE, NJ, NY, CT, MA, RI) due to high wind and coastal storm surge, particularly NY and NJ. Damage from wind, rain and heavy snow. | $71.5 | 159 |

Water's coming up to the first floor now. Water's coming in in the room through the air conditioned vent. Oh, man. You know what? Yeah, these walls are going to start coming in. Are you taping this? Yes. Get back to my spot. So I get. All righty. Storm surge. Oh, yeah, it's coming up now. We're starting to get the worst part of the storm. I think the worst part is still probably a half hour to 45 minutes away. We got things falling apart all around us now. All trees are going down. Storm surge is coming all the way up into the hotel. We got cars starting to get submerged here.
[water wading in]
Let's stick it in the stairwell. We're going to be there soon.
[wind]
[inaudible chatter]
The front bumper is coming off. Oh, hear it? It's getting ready to break, guys. That is about to bust in quick. Here we are. This is crazy.

All right. We're currently on the second floor. The surge has already come up the stairs here. We have five flights to go up if we need to. Look at the first floor the entire floor of the hotel is underwater, and it's continuing to rise. Well, the only shot I can get is out our fourth floor. We're four stories up, and you can see the water. The surge is dramatically risen here. We are in the heart of this is probably pretty close to the eyewall. This is the eyewall. And the eye is probably going to be coming right over our location very soon. This is Mother Nature at her worst right here. This is looking outside our fourth floor window at the holiday inn in Gulfport, Mississippi. This is during the eyewall of Hurricane Katrina. Don't you see the waves coming through. That's coming through the building and still causing waves like that because this is all blocked off on the sides. Here we are on the fourth floor here. The roof collapsed on this building below me. See the roof broke off. The water is receding.

The image shows an aerial view of an urban area heavily affected by flooding. Several buildings, streets, and open spaces are submerged in muddy brown water. In the center, there is a large, partially submerged structure with multiple stories. To its left, bridges span across the floodwaters, linking different parts of the city. Surrounding this central area are various industrial and residential buildings, also surrounded by water. Vegetation and trees are sporadically visible, rising above the waterline. In the background, an overpass and a series of white, industrial-looking rooftops can be seen, indicating a more elevated area. The sky is not visible as the image focuses directly downward on the flood-impacted area.

before and after photographs

Text description of the before and after photographs image.
The image consists of two aerial photographs of the Bolivar Peninsula taken before and after Hurricane Katrina.
The top photograph, dated September 9, 2008, shows a neatly arranged residential neighborhood built on lush green land. Numerous houses with distinct roof shapes and layouts fill the area, bordered by white sand beaches. A large body of water extends toward the horizon. Two houses are highlighted with yellow arrows.
The bottom photograph, dated September 15, 2008, shows the same area after the hurricane’s impact. The once orderly neighborhood is now severely damaged, with widespread debris and many houses destroyed or heavily damaged. The land appears more barren compared to the earlier image. The same two houses are highlighted with yellow arrows, showing that they remain standing and also serving as reference points for spatial orientation within the scene.
