Although areal flood technically gives you more time to prepare for the disaster, it does not mean that they are less destructive or dangerous. However, uninterrupted for several hours or even days, it can eventually lead to overflow of local lakes, rivers, and their connection through local streams and greeks, turning into a massive flood. It happens after a prolonged rainfall that may not be particularly intense. Areal flooding - this type of flooding is more graduate.In fact, Areal flooding and flash flooding are two different events which, although they can happen in the same region, require different preparations and actions.
Many people get confused between these two types of flood warnings and the actions they are supposed to take after receiving them. Areal Flooding Warnings and Flas Flood warnings - what is the difference? In other words, a flood barrier can guarantee your safety even when all other measures like sandbagging or dam-building appear irrelevant. Not only highly efficient even against the most intense water stream, but it also takes only several minutes to install. Once you live in an area prone to such events, it is always better to have a flood protection device like a flood barrier in your garage. Therefore you should start taking action or evacuate immediately. In other words, if a flash flood watch tells you that there is a strong possibility that a flood can happen in your area, a flash flood warning tells you that it is definitely going to happen in the next several hours. It is usually issued after at least a 6-hour heavy rainfall or when a local river or stream`s level goes above their designated flood line. That is why once you live in the area potentially affected by such an event, you should take action immediately.įlash flood warning indicates that the flood is about to occur in the next several hours. That is why although flash flood watch does not give the exact time and even probability of the upcoming flood, once you receive it, you should start taking action, installing your flood barriers, moving to a safer place, and make sure that all family members and most valuable properties are organized and arranged according to your flood action plan.įlash flood watches are also issued if there is a threat of dam break, which may be even more destructive. It is issued to inform residents, emergency services, local authorities, and all cooperating organizations, including volunteers, that developing the weather pattern can probably lead to a flash flood.įlash floods (or rapid floods) are the most dangerous because they are considered the most unpredictable. Let`s go over various warnings you may get when the disaster approaches to work out a clear and efficient action plan.Ī Flash flood watch is technically similar to a tornado watch. Sometimes it may be hard to distinguish between different flash flood watches and warnings, interpret the information and take action on time. Since all low-land water bodies are connected with each other with a complicated system of streams and creeks, which may seem insignificant, you may live next to a flooding hazard your whole life and never understand the danger until a cyclon turns it into a destructive disaster. The main danger of those events is that they easily cause the so-called flash floods, floods that can turn a seemingly peaceful low-land water body like a lake or a small river into a raging water stream.
