At 4:27 a.m. Wednesday, the National Weather Service issued an updated flash flood watch in effect until Friday at 8 p.m. for the South Central Oregon Coast, Curry County Coast, Eastern Curry County and Josephine County, and the Siskiyou Mountains and Southern Oregon Cascades.

The weather service says, “Flooding caused by continued excessive rainfall is possible.”

“Excessive runoff can result in flooding of rivers and streams and low-lying or flood-prone areas. Flooding can also occur in poorly drained and urbanized areas as storm drains and ditches can become clogged with leaves and other debris. There will be an increased risk of rock falls and landslides on steep slopes and road closures,” the weather service explains. “You should monitor later forecasts and be aware of any flood warnings. Those living in areas prone to flooding should be prepared to take action should flooding develop.”

Deciphering advisories, watches and warnings: Understanding weather warnings

• Flood Warning: Take Action!

A flood warning is issued when a flood is either imminent or already occurring. In areas prone to flooding, it is important to immediately move to higher ground. A flash flood is a sudden and violent inundation that can develop within minutes to hours, and it can even occur in areas that are not currently experiencing rainfall.

• Flood Warning: Take Action!

A flood warning is issued when flooding is imminent or occurring.

• Flood Advisory: Be aware of:

A flood advisory is issued when flooding is not expected to be severe enough to issue a warning. However, it can cause significant inconvenience and if care is not taken, it can lead to situations that can threaten life and/or property.

• Flood watch: Be prepared:

A flood watch is issued when conditions are favorable for flooding. It does not guarantee that flooding will occur, but it does mean that the possibility exists.

Weathering the Storm: Flood Safety Guidelines from the Weather Service

In flood-prone regions or when camping in low-lying areas, understanding and following the Weather Service’s flood safety guidelines can be a lifesaver:

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:

If local authorities issue an evacuation order, follow it immediately. Before you leave, secure your home by locking it.

Disconnect tools and appliances:

If time permits, unplug your tools and appliances. This precaution minimizes electrical hazards during flooding.

Stay away from flooded basements and submerged areas:

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

Evacuate immediately for safety:

If you notice sparks or hear buzzing, crackling, snapping or snapping noises, evacuate immediately. Avoid all water that can be charged with electricity.

Refrain from walking in flood waters:

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

Seek higher ground when trapped:

If you become trapped by moving water, get to the highest possible point and call 911 to contact emergency services.

During periods of intense rainfall, the risk of flooding increases, especially in low-lying and flood-prone areas. It is imperative to avoid driving through water on the road, even if it seems shallow. According to the weather service, most cars can be swept away by just 12 inches of rushing water. Stay safe by being prepared and informed.

Driving Through Downpours: Safety Guidelines for Wet Roads

When it rains, safety is paramount. Equip yourself with these weather service guidelines to navigate wet roads and avoid hazards:

Watch out for fast water flow:

Avoid parking or walking near culverts or drainage ditches, as the fast-moving water during heavy rain can potentially wash you away.

Keep safe driving distances:

Follow the two-second rule to maintain a safe 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 efficiency.

Reduce speed and drive carefully:

On wet roads it is of the utmost importance to slow down. Depress the accelerator pedal gradually and avoid sudden braking to prevent skidding.

Choose your file wisely:

Stick to the center lanes to minimize the risk of aquaplaning. Outer lanes are more likely to accumulate water.

Visibility matters:

Improve your visibility in heavy rain by activating your headlights. Pay particular attention to vehicles in blind spots, as rain-smeared windows can obscure them.

Watch out for slippery roads:

The first half hour of rain is when the roads are at their most slippery due to a mixture of rain, dirt and oil. Observe increased 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 quickly and safely.

Consider your windshield wipers:

• Overloaded wiper blades can obstruct visibility. If rain seriously impairs your vision, pull over and wait for conditions to improve. Seek shelter in rest areas or sheltered areas.
• If the shoulder of the road is your only option, pull over as far as possible, preferably past the end of a guardrail, and wait for the storm to pass. Keep your headlights on and turn on your hazard lights 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 of weather conditions and follow guidance from local authorities for a safe journey.
