21 Dec Great Tips On What to do in a Flash Flood and How to Stay Safe During It
It’s pouring outside, and you are stuck inside your home. It’s so heavy you can’t see the street. It is almost like hearing thunder but only for a few seconds, then everything quietens down. What should you do?
To stay safe in a flash flood, it is crucial to be aware of what to do. This blog post will discuss what to do if you are in a flash flood situation and what safety precautions to take after it has passed.
What causes a Flash Flood?
Flash refers to the fact these floods are short-lived – often lasting just a few minutes or an hour. The volume of water involved in these events is called “flood”. Flash floods are when rain falls rapidly and cannot soak into ground before reaching rivers and streams. They rise quickly and take away all they touch.
This can happen in minutes and may occur in certain cases.
Flood vs Flash Flood
Flash floods don’t involve large amounts of water moving across the land, unlike flood. It involves small amounts of water that flows quickly down hillsides or ravines. This is usually due to heavy rain. These flows are slow and rarely reach the river level. Sometimes, however, even a slight rise in stream beds can cause a rapid increase of downstream flow rates.
Are flash floods common?
Flash floods are quite common in the US and can occur at any time after heavy rain. Flash floods are most common after tropical cyclones and thunderstorms, but they can also happen in other situations such as when a dam is damaged.
Because the soil absorbs less water, flash floods are more common in areas with little vegetation. This is especially true if the land was recently cleared for agriculture. Flooding is more common in urban areas.
How to prepare your home for a flash flood
By taking precautions to reduce your risk of flooding, you can lower the likelihood that your home will be affected by a flash-flood. These are:
- Sump pumps Drain excess water from basements and foundations. They are most effective when placed near the basement’s lowest point.
- Elevating floors above grade – Higher floors allow water to drain away from foundation walls, rather than pooling.
- Clearing vegetation near buildings is important. Trees that grow within 10 feet of buildings are more likely to fall under the pressure of strong winds or falling objects. Reduced surface area for water runoff can be achieved by trimming shrubs and bushes. It is also smart for trees to be wind resistant.
- Maintenance of drainage systems – Drainage lines must be maintained clean and free from obstructions. Every few years, pipes leading to catchment tanks must be cleaned. Underground pipe networks allow rainwater to be channeled into catchment tanks, which collect it.
- Flood insurance can be purchased or renewed. Flood insurance is not covered by most homeowner’s policies. It’s important to be protected against flooding before it happens.
Flash Flood Watch: What to Do
Try to prepare for flooding in the event of a flash flooding watch. Flash flood watches are when conditions favor flooding. We offer steps to prepare for a flash flooding watch.
- Regularly inspect your property. You should immediately evacuate if you notice rising water. Do not wait for the worst!
- Prepare disaster supplies, including flashlights and additional batteries.
- Place sandbags on exterior walls. Sandbags placed on external walls act as dams that hold back flood waters.
- Place any items that aren’t needed in your yard, such as patio furniture, securely or safely store them.
- Transfer valuable items to higher levels in your home.
- If they are wet, disconnect them.
What to do During a Flash Flood Warning
Flash flood warnings issued by the National Weather Service and local weather stations should be taken immediately to protect your family and home from flooding. Flash flooding means that flooding is imminent or is already occurring in the area.
Flash flood warnings are a time to stay inside with your doors shut and avoid high places and walls outside. Turn off gas and electrical appliances. Elevators should not be used unless absolutely necessary. Avoid driving in flood areas and be prepared for heavy rains.
When you’re outside, make sure to move to higher ground and avoid rivers, streams, streams, or storm drains. Even moving water a few inches below your feet can sweep you off of your feet. Avoid bridges above water-moving water if you’re driving. Extreme risk is the overflowing of water onto your land, especially if you are outside.
For more information on flash flooding, listen to local radio stations and check local news reports after the warning has ended.
What to Do After a Flash Flood
It is crucial that you notify your insurance company about the flash flood and any damage. Take care when using electrical equipment. Make sure it is dry and checked before you return to use.
