Zion National Park experiences monsoons from mid-July into September that result in an increased risk of flash floods. These floods often occur without warning and can increase water flow by over 100 times. Plan ahead and be prepared. Always be aware of the threat of storms and lightning and be prepared for a wide range of weather conditions. Flash floods, often caused by storms miles away, are a very real danger and can be life threatening. Know the weather and flash flood potential ratings before starting your trip. If bad weather threatens, do not enter a narrow canyon. Three critical steps to flash flood safety are: get to higher ground, do not drive in water, and stay informed. When an area is flooded turn around, don’t drown.
@zionnps will be in modified operations on Wednesday, June 30 due to clean-up activities from yesterday’s flash flood. Motorists should exercise caution. Visitors should expect traffic delays, debris on roads, and potential closures of trails and parking...
