Low-lying roads and locations along the Intracoastal Waterway and adjacent tidal creeks may observe minor coastal flooding. Check with local officials for the latest information regarding coastal flood impacts and closures. Dangerous swimming and surfing conditions and localized beach erosion,” states the weather service. “If travel is required, allow extra time as some roads may be closed.

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 doesn’t guarantee that flooding will occur, but it signifies that the possibility exists.
Navigating floods: weather service flood safety guidelines for weathering the storm
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 allows, disconnect your utilities and appliances. This reduces the risk of 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. Evacuate promptly for safety:If you notice sparks or hear buzzing, crackling, snapping, or popping noises, evacuate immediately. Avoid any water that may be charged with electricity.
6. 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.
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.
Mastering wet roads: Safety tips for heavy rainfall
When heavy rain strikes, safety is paramount. Equip yourself with these guidelines from the weather service to navigate wet roads and avoid hazards:
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 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 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:Overloaded wiper blades can hinder visibility. If rain severely limits your sight, pull over and wait for conditions to improve. Seek refuge at rest areas or protected spots.
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.
