Deciphering advisories, watches, and warnings: Understanding weather alerts

  • 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 declared when flooding is on the verge of happening or is already underway.

  • 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.

When floods strike: Guidelines from the NWS for your protection

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:

Seek 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 allows, disconnect your utilities and appliances. This reduces the risk of electrical hazards during flooding.

Steer clear of flooded basements and submerged areas:

Avoid basements or rooms submerged in water with electrical outlets or cords. Preventing electrical accidents is crucial.

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.

Stay away from floodwaters:

Never attempt to walk through floodwaters. Even just 6 inches of swiftly moving water can forcefully knock you off your feet.

Seek high ground if trapped:

Should you become trapped by moving water, reach the highest point possible and dial 911 to contact emergency services.

During heavy rainfall, the risk of flooding is heightened, especially in low-lying and flood-prone regions. Always remember never to drive through water on the road, no matter how shallow it appears. According to the NWS, as little as 12 inches of rapidly flowing water can carry away most vehicles. Prioritize your safety by staying informed and prepared.

Navigating rainy roads: Safety tips for wet weather

When heavy rain sets in, the risk of flooding and hazardous driving conditions rises. Whether it’s prolonged rainfall or rapid runoff, being prepared is essential. Here are some valuable safety tips from the NWS to ensure you stay safe in heavy rain:

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:

The two-second rule for following distance is your ally in heavy rain. Extend it to four seconds to ensure safe spacing in adverse conditions.

Slow down and stay cautious:

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:

Turn on your headlights and be careful of other vehicles to the rear and in blind spot areas as they are especially difficult to see through rain-spattered windows.

Watch out for slippery roads:

The initial half-hour of rain is when roads are slickest due to a mixture 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.
  • 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.

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.
