JACKSONVILLE, Fla. — As Hurricane Preparedness Week draws toward its close, officials are emphasizing a key, yet often overlooked, message: dangers persist even after the storm passes.

Friday’s theme, “Use Caution After the Storm,” is a reminder to residents in hurricane-prone areas that the aftermath of a storm can be just as deadly as the storm itself. The National Hurricane Center (NHC) warns that nearly half of all hurricane-related fatalities occur after the worst weather is over.

“There have been a substantial number of post-storm fatalities in recent years from tropical storms and hurricanes — especially after major hurricanes,” said Dr. Michael Brennan, director of the NHC. “When you have long-duration power outages, people are at risk. Think about the aftermath of a hurricane in Florida in August or September with no power. It’s going to be really hot. People don’t have air conditioning. We see people succumbing to heart attacks, other medical issues, or accidents that happen during clean-up or while driving around.”

Brennan added that the goal isn’t just surviving the storm but also surviving what comes next.

Always remember also to only return home when local officials declare it safe after an evacuation. Many post-storm hazards — such as downed power lines, gas leaks, unstable structures, and floodwaters — may not be immediately visible.

Flooding remains a top concern, even after a storm’s center has passed. Roads can be washed out or hidden under water, posing a major risk to drivers. Just 12 inches of water can sweep a vehicle away, and floodwaters can carry harmful bacteria, chemicals, sharp debris, and even dangerous animals.

Cleanup efforts must also be approached with caution. Always remember to wear protective gear, working during cooler hours, and staying hydrated. Overexertion during clean-up can lead to serious health issues, including heat stroke and heart attacks which is becoming more and more of a problem in recent years.

Another major threat in the aftermath is the misuse of portable generators. Carbon monoxide poisoning is one of the leading causes of death following hurricanes. Generators should never be used inside homes or garages, even with doors and windows open. They must be placed outside, at least 20 feet from any openings.

Key thing is to be prepared after a major hurricane for extended power outages and how that could impact life and recovery.
