New Orleans is among the most beautiful cities in the country, but unpredictable flash flooding can turn it into a nightmare. Here are some valuable tips for our Springs New Orleans residents from Louisiana's Severe Weather Awareness Week.
What Is a Flash Flood?
Flood conditions usually develop gradually as rivers, lakes and streams become swollen beyond capacity. As the name suggests, flash floods come on suddenly when heavy rainfall occurs in a short amount of time and the soil is unable to absorb it.
Flash floods are more likely to happen in cities than in the country. Roads, pavements and other urban features increase runoff from two to six times the amount generated on natural ground.
During times of flash floods or other severe weather, monitor reports from NOAA weather service or local TV and radio stations.
Difference Between "Watch" and "Warning"
A flood watch, which is more common, indicates that the conditions are right for flooding to occur. A flood warning means that flooding is either underway or imminent within the next 30 to 60 minutes.
Create an Emergency Plan
Since flash floods can happen with no notice, there's a good chance that you and your roommates or family members will be in different places. Put a system in place by which you can all establish contact with each other.
Avoid Moving Water
Even when you're in familiar surroundings, water on the ground can be deceptively deep and hide rocks, holes and other dangers. Did you know that only two feet of rushing water can sweep away heavy vehicles such as buses and tractor trailers?
Whether you're driving or on foot, turn back and seek another route if you encounter water. Head for higher ground whenever possible.
After the Flood
- Continue to follow the news for emergency road closings and other information.
- Stay inside and off the roads unless absolutely necessary to avoid interfering with emergency crews.
- Be cautious even after flood waters have receded, as roads and other structures may have become weakened or damaged.
