In the Safir Simpson system, a category 5 hurricane is already the highest level, which classifies hurricanes from strong to weak into five categories, with wind speeds of more than 250 kilometers per hour and waves at a height of more than 5.5 meters.

Katrina is the product of the interaction of the remnants of 10L and easterly waves, twenty promoted to tropical storms, at which point her path tends to Florida, and just two hours before she makes landfall in Florida, Katrina officially reaches hurricane strength. As a result of the landcut, the system weakened, but an hour after entering the Gulf of Mexico, Katrina regained its former strength.

On August 27, Katrina reached the intensity of a Category 3 hurricane, at this time, Katrina went through a compulsory course that TCs of a certain intensity would encounter------ eye wall replacement, which affected her enhancement, but also a blessing in disguise, and Katrina's circulation doubled, after the replacement, Katrina reached the strength of a Category 5 hurricane on the 28th and peaked at 1 p.m. (CDT), with a maximum wind speed of up to 175 miles near the center and a minimum pressure of 902HPA。

On the 29th, Katrina made landfall in Louisiana at 6:10 a.m. with a maximum wind speed of 125 miles and a 190-kilometer wind circle radius for the hurricane, followed by a third landfall with winds of 120 MPH on the border between Louisiana and Mississippi.

New Orleans is located between the 800-meter-wide Mississippi River and Lake Pontchatre, with an average altitude below sea level, and the lowest point is up to three meters below sea level.

The city of New Orleans, a city with an average elevation below sea level and a long-time patron of hurricanes, was the hardest hit by the city, but its breakwaters were estimated to be unable to withstand waves caused by hurricanes of Grade 3 or higher, so when the hurricane hit, the breakwaters were quickly breached.

The river and the sea joined together, flooding the entire city, with an average depth of two and a half meters, and the thriving city became a vast ocean, and there were even alarming rumors of sharks rushing into the city center.

More than 20,000 people have taken refuge in the conference center and sports center in the city center alone, waiting for rescue.

Wherever the hurricane passed, the damage to infrastructure was devastating, with houses collapsing, roads and bridges washed away, and electricity, communications and water supply disrupted.

The wind and the torrential rain, as if to destroy everything and tear it apart, the main body of this villa is a reinforced concrete structure, it is still quite strong, but the huge wind speed seems to blow the house away, Mark through the window, he saw the bucket-thick trees break at the waist, and then blow away, he saw a car on the side of the road actually scraped down like a garbage can, all this is too scary, the hurricane here, at most three levels, you can imagine, the five hurricanes when they first landed, how amazing.

Fortunately, Mark reinforced the windows with wooden boards, otherwise the windows would have been blown out, and there were eight of them here, Mark, Giselle plus four assistants, and a housekeeper and servant of the villa, who were usually responsible for maintaining the villa, and Mark told everyone to hide in the basement, which was safer.

Now everyone thinks that Mark's approach is very correct, seeing so much food and water in the house, there is food in his hand and he does not panic, even if he does not go out for a month or two, there is no problem.

Mark asked the butler to take out the two guns in reserve, and Mark said, "The situation is chaotic now, in case someone takes advantage of the fire to rob it." ”

Mark refueled the gun and filled it with bullets, and over the years, every month he would find time to go to the shooting club to practice shooting.

After the hurricane, it was pouring rain, and it rained all night, and it was nine o'clock in the morning, but the sky was still full of dark clouds, and there was no sunlight, when there was a knock at the door, and the housekeeper went to open the door, and found a family of four standing outside the door, although they were wearing raincoats, they were all soaked, and they were extremely embarrassed.

The housekeeper asked Mark for instructions: "The nearby Shamir family, their windows are broken, and the rainwater is pouring in, for safety, they want to come here to take shelter from the rain." ”

Mark muttered, "Can you trust it? Safety comes first at this time. ”

"They are all neighbors, they live half a kilometre away, and Mr. Shamir is a nice guy who runs a small bar," said the housekeeper. ”

Mark nodded.

The housekeeper went out and brought in Shamir's family, four of them, Shamir and his wife and a pair of daughters, and saw that they were all soaked, and the two little girls shivered with cold on such a September day, and brought them clean

Changing their clothes and towels, and drinking warm milk, Shamir thanked Mark: "Thank you very much for taking us in, Mr. Mark Wang. "He recognized Mark.

Mark said: "You're welcome, helping others is a joy. He said to the two little girls who were looking curiously at the food in the hall, "Isn't it great? The house is full of food, and here is a free supermarket to choose from, you can take what you like." ”

The two little girls said happily, "Really?

Mark said, "Yes. The two little girls cast inquiring glances at their mother, and when their mother nodded, they ran happily to pick up snacks.

Shamir looked at the room full of food and the plank-fastened windows, and said, "You are well prepared. ”

Mark said, "It is not wrong to be prepared, Mr. Shamir, how many families are there nearby? If they don't have a place to go, I have some rooms here that can accommodate some people." ”

Shamir was overjoyed and said: "God will bless you, the residents of the town should have taken refuge in schools and bomb shelters, but there are more than a dozen families nearby, their houses are made of reinforced concrete, they think there is no problem, they do not go out, but they take shelter in their homes or cellars, and we are the same, but the windows are broken, and a lot of rain is blowing in, I can go and visit." ”

"It's raining heavily. ”

Shamir said: "I can go by car, it's no problem to drive a little slower." ”

Mark said, "I'll go with you." ”

Shamir asked, "You?"

Mark said: "I'm not a city guy who can't endure hardship. As soon as they arrived at the door, more than a dozen people from two families drove three cars, and their house was also flooded, so they had to brave the rain to rush to the largest villa in the neighborhood for help.

Mark and Shamir drove to pick up more than a dozen families in the vicinity, the hurricane was far stronger than estimated, and each house was damaged to varying degrees, and now Mark and his family reached out and moved in immediately.

Mark is mindful, he made it clear to Shamir that he only accepts those who have families, preferably women and children, and for those hooligans, he will refuse and never accept them, which Shamir also understands that his wife and children are also in the villa, and he doesn't want them to stay with those black sheep, so he has silently avoided this kind of family.

When they returned in the afternoon, it was full of people, as lively as a hotel, and Giselle commanded a few assistants to greet the guests, and it could generate its own electricity, but it was not very powerful, it was limited to electricity, and the water was dug in wells and pumped into the storage tank for backup, and it was not affected.

It gives people a warm and happy feeling, and almost everyone exclaims, "It's full of food." ”

Mark returned, they all expressed their gratitude, thanks to the host for his hospitality, now it is still raining heavily, communication is also interrupted, according to rumors, the small pier was flooded, the only bridge to the outside was also washed away by the flood, the people of the town can not go out, the people outside can not come in, everyone is a little worried, no one expected that the hurricane is so destructive, and now it is raining again, who knows what else will happen?

Seeing that people were so worried, Mark and Shamir drove back into town, and they had to drive slowly because it was pouring rain and visibility was extremely low.

It's a small town, and the sheriff and sheriff are the same person, and the sheriff's office is together, and they're here because there's a radio here, and they can communicate with the outside world.

However, when they came to the police station, they saw a rather hot scene, and a few guys who knew at first glance that they were not good birds confronted the police with guns.

When Shamir saw this, he pulled out his gun, pointed it at the gang, and said loudly, "Mad Dog Billy, do you want to become a dead dog Billy?" Mark also raised his shotgun and pointed it at the other party.

Mad Dog Billy originally confronted the police and was not left behind, but the back road was copied, and the situation immediately reversed, and he said loudly: "Damn Shamir, you don't have to be in such a hurry to see God." "The guy with the shotgun next to Shamir gave him a headache, and the shot hit him, killing him and wounding him.

The sheriff shouted: "Mad dog Billy, you have the upper hand, if you want to get out of here alive, put down your gun, the governor has ordered that anyone who takes advantage of the fire to rob can be shot immediately." ”

Mad Dog Billy looked at the pale faces of several of his men, and knew that they were scared and didn't dare to fight hard, he gritted his teeth and said sharply: "I want to get out of here, and those who stand in my way will die." ”

Mark pulled the insurance and said, "Yes, as long as I have a buckle machine, you're all finished, do you want to try it?"

The sheriff said: "You will be in prison for three or five years at most, and you will die if you shoot, do you really want to die?" They are now fighting back and forth, suppressing each other to the death, just taking the opportunity to take advantage of these few evildoers, these people dare to go straight to the police station with guns, God knows what else they will do, he doesn't want to miss it.

Mad dog Billy broke out in a cold sweat, he miscalculated today, he couldn't save his brother, he couldn't grab the goods, he even had to get in, he couldn't make up his mind whether to surrender or kill out.
