Your guide to weather alerts: 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 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.

Keeping safe during floods: Expert advice from the weather service

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 weather service offers essential flood safety guidelines:

1. 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.

2. Adhere to evacuation orders:

• If local authorities issue an evacuation order, heed it promptly. Prior to leaving, secure your home by locking it.

3. Disconnect utilities and appliances:

• If time permits, disconnect your utilities and appliances. This precaution minimizes electrical hazards during flooding.

4. 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.

5. 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.

6. 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.

7. 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 weather service, as little as 12 inches of rapidly flowing water can carry away most vehicles. Prioritize your safety by staying informed and prepared.

Navigating heavy rain: Essential safety measures for wet roads

Rain can turn roads into hazards. Stay informed and follow these weather service tips 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.

Slow down and stay cautious:

• 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:

• Stay toward the middle lanes – water tends to pool in the outside lanes.

Visibility matters:

• 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 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 them swiftly 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.

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.
