Understanding Storm Surge: Important Information as Hurricane Helene Approaches Florida

Storm surge is a major threat from Hurricane Helene, which is expected to hit Florida as a major hurricane on Thursday.

Helene is a large storm, so it could bring life-threatening storm surge for the entire west coast of the Florida Peninsula.

Storm surge could reach 15 to 20 feet in the Florida Panhandle. The Tampa area could get 4 to 8 feet of storm surge.

Here is how storm surge works and why it’s so dangerous:

When pressure falls in the center of the hurricane, water levels rise, and the water amasses while the storm is still over the open ocean.

As the hurricane nears the shore, strong winds push that amassed water toward the coast and onto land.

This can build walls of water — potentially as tall as 20 feet or more — which can quickly overpower walls and flood homes.

In 2005, during Hurricane Katrina, at least 1,500 people died “directly, or indirectly, as a result of storm surge,” according to the National Hurricane Center.

The risks can be even greater if storm surge combines with high tide, which could quickly create a catastrophic rise in water levels.

As Hurricane Helene approaches Florida, it is important for residents to understand the potential threat of storm surge. Storm surge is one of the most dangerous and destructive aspects of a hurricane, and it is crucial to be informed and prepared.

What is storm surge?

Storm surge is the abnormal rise in water level along the coast that is caused by a hurricane or tropical storm. It is often the most deadly and destructive part of a hurricane, as it can cause widespread flooding and significant damage to coastal areas. Storm surge is driven by the strong winds and low pressure of a hurricane, which push water towards the shore and cause it to pile up.

How does storm surge impact Florida?

Florida is particularly vulnerable to storm surge due to its long coastline and low-lying terrain. The state has experienced devastating storm surge in the past, most notably during Hurricane Katrina in 2005 and Hurricane Irma in 2017. In some areas, storm surge can reach heights of 20 feet or more, inundating homes, roads, and infrastructure.

What can residents do to prepare for storm surge?

As Hurricane Helene approaches Florida, residents should take the following steps to prepare for potential storm surge:

– Stay informed: Monitor weather updates from local authorities and the National Hurricane Center to stay informed about the storm’s track and potential impacts.

– Evacuate if necessary: If you live in a coastal area that is at risk of storm surge, follow evacuation orders from local officials. Do not wait until the last minute to evacuate, as roads may become impassable.

– Secure your property: Protect your home by boarding up windows, securing loose outdoor items, and moving valuables to higher ground. Consider purchasing flood insurance to protect against damage from storm surge.

– Have an emergency kit: Prepare an emergency kit with essential supplies such as food, water, medications, and important documents. Include items like flashlights, batteries, and a first aid kit.

– Stay safe: During the storm, stay indoors and away from windows. Do not attempt to drive through flooded roads or walk through standing water. Follow all safety instructions from local authorities.

In conclusion, understanding storm surge is crucial for residents of Florida as Hurricane Helene approaches. By staying informed, preparing your property, and following evacuation orders, you can protect yourself and your loved ones from the potentially devastating impacts of storm surge. Stay safe and be prepared.
