Understanding the differences between advisories, watches, and warnings
- Flash flood warning: Take action!
A flash flood warning is issued when a flash flood is imminent or occurring. If you are in a flood-prone area, move immediately to high ground. A flash flood is a sudden violent flood that can take from minutes to hours to develop. It is even possible to experience a flash flood in areas not immediately receiving rain.
- Flood warning: Take action!
A flood warning is issued when flooding is imminent or occurring.
- Flood advisory: Be aware:
A flood advisory is issued when flooding is not expected to be bad enough to issue a warning. However, it may cause significant inconvenience, and if caution is not exercised, it could lead to situations that may threaten life and/or property.
- Flood watch: Be prepared:
A flood watch is issued when conditions are favorable for flooding. It does not mean flooding will occur, but it is possible.
Keeping safe during floods: Expert advice from the NWS
Floods can pose a significant threat, especially if you live in a flood-prone area or find yourself camping in a low-lying region. To ensure your safety, the NWS offers essential flood safety guidelines:
Move to higher ground:
If you’re in a flood-prone area, or if you’re camping in a low-lying spot, move to higher ground as a first step.
Adhere to evacuation orders:
If local authorities issue an evacuation order, heed it promptly. Prior to leaving, secure your home by locking it.
Disconnect utilities and appliances:
If time allows, disconnect your utilities and appliances. This reduces the risk of electrical hazards during flooding.
Steer clear of flooded basements and submerged areas:
Steer clear of basements or rooms where water has submerged electrical outlets or cords. This helps prevent electrical accidents.
Swift evacuation for your safety:
If you notice sparks or hear buzzing, crackling, snapping, or popping sounds, evacuate without delay. Do not enter water that may carry an electrical charge.
Refrain from walking in floodwaters:
Never attempt to walk through floodwaters, even if they appear shallow. Just 6 inches of fast-moving water can forcefully sweep you off your feet.
Seek higher ground when trapped:
Should you become trapped by moving water, reach the highest point possible and dial 911 to contact emergency services.
When heavy rain occurs, there is a risk of flooding, particularly in low-lying and flood-prone regions. It is important to never attempt to drive through water on the road, regardless of how deep it appears. According to the NWS, as little as 12 inches of rushing water can sweep away most vehicles. Stay safe by being prepared and informed.
Navigating rainy roads: Safety tips for wet weather
When heavy rain pours, the risk of flooding and treacherous roads rises. Here’s your guide from the NWS to staying safe during downpours:
Beware of swollen waterways:
Avoid parking or walking in close proximity to culverts or drainage ditches, as the swiftly moving water during heavy rain can potentially carry you away.
Maintain safe driving distances:
Adhere to the two-second rule for maintaining a safe following distance behind the vehicle in front of you. In heavy rain, allow an additional two seconds of distance to compensate for reduced traction and braking effectiveness.
Slow down and drive with care:
If it is raining and the roads are wet, slow down. Take your foot off the accelerator and let your speed drop gradually. Never use the brakes suddenly because this may cause the car to skid.
Choose your lane wisely:
Stick to the middle lanes on multi-lane roads to minimize the risk of hydroplaning, as water tends to accumulate in outer lanes.
Prioritize visibility:
Enhance your visibility in heavy rain by activating your headlights. Be particularly vigilant for vehicles in blind spots, as rain-smeared windows can obscure them.
Watch out for slippery roads:
The first half-hour of rain is when roads are slickest due to a mix of rain, grime, and oil. Exercise heightened caution during this period.
Keep a safe distance from large vehicles:
Don’t follow large trucks or buses too closely. The spray created by their large tires reduces your vision. Take care when passing them as well; if you must pass, do so quickly and safely.
Mind your windshield wipers:
- Heavy rain can overload the wiper blades. When visibility is so limited that the edges of the road or other vehicles cannot be seen at a safe distance, it is time to pull over and wait for the rain to ease up. It is best to stop at rest areas or other protected areas.
- When stopping by the roadside is your only option, position your vehicle as far off the road as possible, ideally beyond guardrails. Keep your headlights on and activate emergency flashers to alert other drivers of your position.
By following these safety measures, you can significantly reduce risks and ensure your well-being when heavy rain pours down. Stay informed about weather conditions and heed advice from local authorities to make your journey safe and sound.
