Watch Out For Flooding in El Yunque
Flash floods can occur throughout the year, but can be more frequent during the rainy months of April and May. A flash flood is a serious weather event for forest visitors because rising flood water is extremely dangerous—a sudden surge can claim victims in less than one minute.
Any intense, heavy rain that falls in a short amount of time can create flash flood conditions especially in low-lying areas and it can happen at a moment’s notice any time of the year.
During a flash flood, rapidly rising water can reach heights of 30 feet or more. The velocity of a flood surge can easily roll boulders and vehicles, tear out trees, destroy bridges and undermine roads. A low-lying area can become a death trap in a matter of minutes.
There is very little time to react. Forest visitors need to be conscious about sudden storms. Visitors and families should discuss how they would alert each other and climb to safety if rushing water arrives.
Weather experts say the best defense is to be weather-ready before a storm hits. Forest officials are asking visitors and neighbors to check the National Weather Service forecast before they leave home, and to be alert for changing weather conditions while visiting the forest. Devices like a weather radio, a terrestrial radio, a smart-phone app or a cell phone mobile alert can help visitors stay tuned-in before and during their outdoor activities.
The National Weather Service issues flash flood watches and warnings which are transmitted on NOAA weather radios and through local media. A flash flood watch means threatening weather is possible in the area. A flash flood warning means you may have only seconds to escape. A flash flood can happen so rapidly that you may not get a warning. If a flash flood warning is issued for your area, go to safety immediately.
