Best Way to Stay Safe Amid Rising Flood Risks During Yellow Weather Warnings

The Met Office uses a tiered system to communicate flood risks, which is essential for understanding how to respond:

• Flood Watch (Be Prepared): Conditions are favorable for flooding, but it’s not guaranteed. This is the time to monitor updates and prepare.
• Flood Warning (Take Action): Flooding is imminent or already occurring. Immediate action is required to protect life and property.
• Flash Flood Warning (Urgent Action Needed): Rapid flooding is happening or expected soon, often with little notice. Move to higher ground immediately.

Knowing these distinctions can help you take appropriate actions when alerts are issued.

Before the Flood:

Preparation can significantly reduce risks associated with flooding. Here’s what you can do:

• Stay Informed: Regularly check updates from trusted sources like the Met Office, Natural Resources Wales (NRW), or local councils. Use apps or radios for real-time alerts.
• Create an Emergency Kit: Include essentials such as bottled water, non-perishable food, flashlights, batteries, first-aid supplies, warm clothing, and important documents in waterproof containers.
• Protect Your Property: Clear drains and gutters to prevent water buildup. Use sandbags to block entry points around doors and windows if flooding is expected.
• Review Insurance Policies: Ensure your home insurance covers flood damage. Many policies require additional coverage for this specific risk.
• Plan Evacuation Routes: Identify safe routes to higher ground in case evacuation becomes necessary.

During the Flood:

When flooding begins or warnings escalate, follow these critical safety measures:

• Turn Around, Don’t Drown®: Never attempt to walk or drive through floodwaters. Just 6 inches of fast-moving water can knock over an adult, while 12 inches can carry away most cars.
• Obey Barricades: Do not bypass road closures due to flooding; roads may have collapsed under water or be hiding other hazards.
• Move to Higher Ground: If you live in a flood-prone area or near rising rivers or streams, relocate immediately to a safe location.
• Avoid Electrical Hazards: Stay away from downed power lines or electrical equipment in flooded areas as water conducts electricity and poses life-threatening risks.

After the Flood:

Once floodwaters recede, dangers may still remain:

• Avoid Standing Water: Floodwaters often contain toxins, chemicals, sharp objects, or hidden structural damage such as collapsed roads.
• Wait for Clearance: Do not enter flood-damaged buildings until authorities declare them safe.
• Check Drinking Water Safety: Authorities may advise boiling water before use to ensure it is free from contaminants.
• Document Damage: Take photos of any damage for insurance claims and report issues like blocked drains or damaged infrastructure to local councils.

Community Support and Awareness

Helping others during floods is equally important:

• Check on vulnerable neighbors who may need assistance with evacuation or securing their homes.
• Share safety information on social media using campaigns like “Turn Around, Don’t Drown®” to raise awareness about flood risks.
• Contact local emergency services for sandbags or temporary shelter if needed.

The Rising Threat of Floods

Climate change is contributing to more frequent extreme weather events globally, including in Wales. Recent yellow weather warnings have brought record rainfall levels—up to 100mm in a single day—causing significant disruptions in communities across South Wales during Storm Bert in 2024. In Pontypridd alone, residents faced repeated flooding incidents due to insufficient defenses along the River Taff.

The UK government has invested £2.6 billion in new flood schemes designed to better protect 300,000 homes by 2021; however, challenges remain as extreme weather events become more common. Enhanced forecasting methods by the Met Office and Environment Agency have proven effective but require continued development as climate variability increases.

By staying informed and taking timely precautions before, during, and after floods, individuals can greatly minimize risks and protect their families and properties from harm. Proactive measures—such as monitoring updates from the Met Office’s Flood Forecasting Centre—are critical in mitigating the impact of extreme weather events on communities across Wales and beyond.
