Coastal Flood Safety Cheat Sheet: Essential Tips for Protection

Coastal flooding poses significant risks to communities along the U.S. coastline. Understanding the causes, recognizing warning signs, and implementing safety measures are crucial for protection. This guide provides essential information to help you prepare and respond effectively to coastal flood threats.

What Causes Coastal Flooding?

Coastal flooding occurs when water inundates normally dry coastal land due to high or rising tides, storm surges, or other factors. Common causes include:

  • Storm Surges: Elevated sea levels caused by intense offshore low-pressure systems, such as hurricanes or tropical storms.

  • High Tides: Elevated sea levels during periods of high tide, which can lead to flooding in vulnerable areas.

  • Sea-Level Rise: Long-term increases in sea levels due to climate change, contributing to more frequent and severe flooding events.

Understanding Flood Warnings and Watches

The National Weather Service (NWS) issues specific alerts to inform the public about potential flooding:

  • Coastal Flood Watch: Issued when coastal flooding is possible within 12 to 36 hours. Residents should be prepared to take action if flooding occurs.

  • Coastal Flood Warning: Issued when coastal flooding is occurring, imminent, or expected within 12 hours. Immediate action is necessary to protect lives and property.

Safety Measures Before, During, and After a Flood

Before a Flood: Prepare by taking the following steps:

  • Know Your Risk: Determine if you live in a floodplain by consulting FEMA's online map service center. (weather.gov)

  • Create a Family Disaster Plan: Develop a communication plan and list of contacts.

  • Secure Important Documents: Store insurance policies, identification, and other critical documents in a safe deposit box.

  • Assemble a Disaster Supplies Kit: Include essentials like water, non-perishable food, medications, and a flashlight.

During a Flood: Follow these guidelines to stay safe:

  • Stay Informed: Monitor local news, NOAA Weather Radio, and official websites for updates.

  • Evacuate if Necessary: If authorities advise evacuation, do so immediately. Lock your home when you leave. (weather.gov)

  • Avoid Floodwaters: Do not walk, swim, or drive through floodwaters. Just six inches of moving water can knock you down, and one foot can sweep your vehicle away. (ready.gov)

After a Flood: Take these steps to ensure safety:

  • Wait for Official All-Clear: Return home only when authorities confirm it's safe.

  • Inspect for Hazards: Check for structural damage, gas leaks, and electrical issues.

  • Avoid Contaminated Water: Boil drinking water before use, as floodwaters can contaminate water supplies. (weather.gov)
