Understanding the differences between advisories, watches, and warnings
Flash flood warning: Take action.
A flash flood warning is issued when a flash flood is either imminent or already occurring. In flood-prone areas, it’s crucial to move immediately to higher ground. A flash flood is a sudden and violent inundation that can develop within minutes to hours, and it can even happen in areas not currently experiencing rainfall.
Flood warning: Take action.
A flood warning is declared when flooding is on the verge of happening or is already underway.
Flood advisory: Be aware.
A flood advisory is released when flooding is not expected to reach a severity level necessitating a warning. Nonetheless, it can still cause considerable inconvenience and, without exercising caution, potentially lead to situations that 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
In flood-prone regions or while camping in low-lying areas, understanding and following the NWS flood safety guidelines can be a lifesaver:
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.
Follow evacuation orders:
When local authorities issue an evacuation order, promptly comply. Before leaving, secure your home by locking it.
Disconnect utilities and appliances:
If time permits, disconnect your utilities and appliances. This precaution minimizes electrical hazards during flooding.
Avoid basements and submerged areas:
Avoid basements or rooms submerged in water with electrical outlets or cords. Preventing electrical accidents is crucial.
Evacuate promptly for 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 just 6 inches of swiftly moving water can forcefully knock you off your feet.
Seek higher ground when trapped:
In the event you become trapped by moving water, make your way to the highest point available and contact emergency services by calling 911.
During heavy rain, flooding is possible, especially in low-lying and flood-prone areas. Never drive through water on the road, even if it does not appear to be deep. It takes just 12 inches of rushing water to carry away most cars, according to the NWS. Prioritize your safety by staying informed and prepared.
Rainy roadways ahead: Essential safety tips for heavy rain
Rain can turn roads into hazards. Stay informed and follow these tips from the NWS to ensure safety during heavy rainfall:
Beware of swollen waterways:
During heavy rain, avoid parking or walking near culverts or drainage ditches, where swift-moving water can pose a serious risk.
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.
Reduce speed and drive cautiously:
On wet roads, reducing your speed is crucial. Ease off the accelerator gradually and avoid abrupt braking to prevent skidding.
Choose your lane wisely:
Stick to the middle lanes to minimize the risk of hydroplaning. Outer lanes are more prone to accumulating water.
Visibility matters:
Enhance your visibility in heavy rain by turning on your headlights. Watch out 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:
Large trucks and buses can reduce your visibility with tire spray. Avoid tailgating and pass with caution.
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.
• If the roadside is your only option, pull off as far as possible, preferably past the end of a guard rail, and wait until the storm passes. Keep your headlights on and turn on emergency flashers to alert other drivers of your position.
In the face of heavy rain, these precautions can make a significant difference in ensuring your safety on the road. Remember to stay informed about weather conditions and heed guidance from local authorities for a secure journey.
