Recent news clips have indicated that roughly half of the counties in Louisiana are included in the Presidential Disaster Declaration for the severe flooding there. Here are some of the first indicators of how serious and unusual those floods are.
Disasters like Louisiana floods will worsen as planet warms, scientists warn. National Oceanic and Atmospheric Administration to classify disaster as the eighth flood considered to be a once in every 500-year event in the US in a year
On Tuesday, the National Oceanic and Atmospheric Administration (NOAA) is set to classify the Louisiana disaster as the eighth flood considered to be a once in every 500-year event to have taken place in the US in little over 12 months.
Since May of last year, dozens of people have been killed and thousands of homes have been swamped with water in extreme events in Oklahoma, Texas, South Carolina, West Virginia and Maryland. NOAA considers these floods extreme because, based on historical rainfall records, they should be expected to occur only once every 500 years.
The Louisiana flooding has been so exceptional that some places in the state experienced storm conditions considered once-every-1,000-year events. Close to two feet of rain fell over a 48-hour period in parts of southern Louisiana, causing residents to scramble to safety from flooded homes and cars.
Another possible record setter is the number of people needing shelter. See: Red Cross Sheltering Thousands Affected by Unprecedented Flooding in Louisiana
