Know the Dangers of the Storm
What many people do not think of, especially if they are not from the Caribbean or have never experienced a hurricane before, are the dangers of the sea: the high, crashing waves and rising sea level (storm surge) that cause sea water to come inland and combine with the rain to produce sudden, severe, even life-threatening flooding.
A storm surge is a rise in the level of the sea. It occurs as storm winds push water forward.
As the storm nears land, the water builds up to several feet above normal sea level, add to this the waves, which ride on top of the already high seas. These waves, themselves several feet high, can crash hundreds of yards inland in a severe storm, battering structures by their own force and the force of rocks and other objects in them. These often destroy and pull out to sea everything in their path, including structures tens of feet above normal sea level.
As the Cayman Islands are low-lying (particularly Grand Cayman and Little Cayman), small and narrow, they are vulnerable to storm surge and to dangerous wave action. In any case, severe flooding from rain, waves and/or surges can affect any area of the islands, depending on the strength of the particular storm, the path it is travelling, and how close its centre comes to land.
Structures on or near the waterfront are always the most vulnerable (all coastal and canal-front areas, including land bordering the North Sound). So are the narrowest sections of land: Little Cayman; the western end of Cayman Brac; and, on Grand Cayman, Prospect to West Bay. It is important to know however, that any structure, anywhere in the islands that is not built or reinforced to hurricane-resistance standards is at risk.
When It Matters Most, Know Where to Turn
Preparedness is power. Be ready everyday.
Every hurricane season reminds us that preparedness is not just about supplies, shutters or storm plans. It is about access to timely, trusted information when people need it most.
In moments of uncertainty, knowing where to turn can make all the difference.
That is why the Cayman Islands Government continues to strengthen its official digital channels, including GOV.KY, CaymanPrepared.ky, WhatsApp, Facebook, Instagram and YouTube, to ensure the public can access verified alerts, important updates and recovery information before, during and after a storm.
Preparedness Starts Before the Storm
Storms can develop quickly. Rumours and misinformation can spread even faster.
Official government channels are designed to help residents make calm, informed decisions with confidence. Whether it is school closures, shelter information, weather warnings, service disruptions or recovery support, these platforms provide information directly from trusted sources.
By following official channels ahead of time, residents can stay connected to the updates that matter most without having to search across multiple sources during an emergency.
Digital Channels That Support Community Resilience
Preparedness is a shared responsibility. Strong communities are built when people look out for one another, share reliable information and act early.
Digital communication now plays a critical role in national readiness and recovery. GOV.KY and the Cayman Islands Government’s social media channels help ensure that critical information can reach people quickly, wherever they are.
These channels are not only tools for communication, they are part of how Cayman builds resilience together.
Stay Connected This Hurricane Season
Residents are encouraged to bookmark GOV.KY and CaymanPrepared.ky and follow the Cayman Islands Government on WhatsApp, Facebook, Instagram and YouTube before a storm threatens.
Being prepared starts with staying informed.
Because when it comes to storms, Cayman doesn't face them alone - we face them together.
