Hurricane “Aida” is known to have killed four people, but the death toll is expected to increase.

The United Nations said on Wednesday that Hurricane Aida, which hit the U.S. Gulf Coast over the weekend, could be the costliest weather disaster on record.

Louisiana and Mississippi are still aware of disasters caused by powerful Category 4 storms that occurred just 16 years after Hurricane Katrina landed and devastated the region.

Ida is known to have killed four people Number of deaths Expected to increase, he destroyed over a million properties across Louisiana.

Economic cost He will be higher than Katrina. Petteri Taaras, head of the United Nations World Meteorological Organization (WMO), told reporters in Geneva.

He pointed to “severe damage to Louisiana’s electrical system” as an example.

To date, Katrina, which has killed more than 1,800 people and destroyed most of New Orleans, has been considered the costliest weather disaster to date.

Mortality and Economic loss Extreme weather, climatic and hydrological conditions from 1970 to 2019 showed Katrina caused an economic loss of almost $ 164 billion.

Today, Hurricanes Harvey and Maria in 2017 are considered the second and third costliest weather disasters, with prices of nearly $ 97 billion and over $ 69 billion, respectively.

Taalas said it would likely take more than a month to get a full cost estimate for the losses caused by Ida.

But he welcomed the improvement Early warning Flood protection systems and evacuation procedures appeared to save many lives.

“For Aida, the good news is that there were a lot fewer casualties compared to Katrina,” Taaras said.

United Nations Secretary-General Mami Mizutori Disaster risk reductionI agreed.

She told reporters that the difference between the effects of the two storms shows the importance of investing in prevention.

“The economic losses will certainly be significant enough, but the good news is… the death rate is very, very low, and that’s because the cities of New Orleans and Louisiana… have invested in prevention. . “

The biggest difference since Katrina has been the $ 14.5 billion investment in building flood walls and dikes as part of the new “Hurricane and Storm Risk Reduction System”.

“They didn’t wait until the next century to do it. They did it very quickly. “
