Short answer: prepare before June, not when a storm is named
Atlantic hurricane season officially runs from June through November, with peak risk usually later in the summer and early autumn. Cayman Islands National Weather Service material for the 2026 season points to a below-average Atlantic outlook, but still reminds residents that one local impact can make a season serious. New residents should prepare at the beginning of the season: supplies, insurance documents, shutters, generator or backup power, medications, pet plans, official alert channels, and a clear household decision tree for staying, sheltering, or leaving.
- Do a home readiness check before June: shutters, drainage, roof, windows, doors, trees, generator, and storage areas.
- Buy supplies early. Waiting until a watch or warning creates shortages and stress.
- Keep insurance, passports, work permits, leases, medical records, and banking documents backed up digitally and waterproofed physically.
- Sign up for HMCI's National Emergency Notification System and bookmark Cayman Islands National Weather Service hurricane updates before a storm forms.
- If you live near the sea, canal, low-lying areas, or older buildings, understand flood and storm-surge exposure before a storm threatens.
Build an official alert and shelter file
Your emergency information should not depend on informal group chats. Hazard Management Cayman Islands coordinates national disaster preparedness and publishes hurricane, shelter, emergency-number, family-plan, and National Emergency Notification System information. Cayman Islands National Weather Service publishes weather alerts, hurricane updates, forecasts, and severe-weather warning context. Put those channels into the same offline file as your landlord, strata, insurer, utility, doctor, school, employer, and pet-care contacts.
- Do not wait for a warning to decide whether your home is suitable; decide your shelter, friend, hotel, or off-island threshold in advance.
- If you have infants, pregnancy, medical devices, mobility needs, pets, or no reliable transport, make the shelter or relocation decision earlier than a low-risk household would.
- Print or screenshot key pages because power, WiFi, and mobile data may become unreliable during and after a storm.

Know your home before hurricane season
Your hurricane plan starts with your property. A modern concrete condo with shutters and a high elevation has different risks from an older standalone house, a canal-front property, a low-lying rental, or a home with large trees and poor drainage.
- Renters should ask landlords in writing what storm preparation they handle and what the tenant must do.
- Condo residents should know strata rules for balcony furniture, shutters, generators, pets, parking, and post-storm access.
- Trim trees and secure loose outdoor items before the season, not during storm prep hours.
| Home factor | Why it matters | Ask/check this |
|---|---|---|
| Shutters/windows | Wind and debris protection | Are shutters installed, complete, labelled, and usable? |
| Elevation/flood history | Storm surge and heavy rain risk | Has the property flooded before? |
| Roof/gutters/drainage | Water intrusion risk | When were roof, gutters, drains, and seals last checked? |
| Generator/backup power | Outage resilience | What does it power, who maintains it, and is fuel safe? |
| Strata/landlord plan | Shared buildings need coordination | Who installs shutters and handles common-area prep? |
Insurance and documents
Insurance is one of the most important hurricane preparation tools. CIMA's June 2026 hurricane-season guidance tells residents to review policies with an insurer or broker, understand whether hurricane, flood, earthquake, tsunami, deductibles, exclusions, sub-limits, and add-ons apply, and check sums insured against current replacement costs. New residents should do this before a storm exists. Property, contents, motor, health, travel, and renters insurance all have different roles, exclusions, limits, and deductibles.
- Homeowners: review building insurance, storm/wind deductibles, flood/water exclusions, contents, loss of use, and claim documentation requirements.
- Renters: ask whether you need contents/renters coverage; the landlord’s policy usually does not protect your belongings.
- Car owners: confirm comprehensive coverage, flood/water damage, and where to park during a storm.
- Condo buyers and renters: ask how the strata master policy, reserves, hurricane procedures, balcony rules, generators, lifts, and common-area claims would work.
- Photograph property, furniture, electronics, appliances, valuables, passports, IDs, permits, and insurance policies before the season.
- Keep cloud backups plus a waterproof physical document pouch.
Supplies: what new residents actually need
The goal is not panic buying. The goal is to function safely for several days if power, water, roads, shops, ATMs, mobile networks, or fuel access are disrupted. Stock practical supplies before peak season and rotate food, batteries, medications, and water over time.
| Category | What to prepare | Newcomer note |
|---|---|---|
| Water | Drinking water plus washing/flushing backup | Do not rely only on shops after a warning. |
| Food | Shelf-stable meals, snacks, pet food, baby food | Choose food your household will actually eat. |
| Power/light | Flashlights, lanterns, batteries, power banks, UPS | Candles are less safe than LED lights. |
| Medical | Prescriptions, first aid, glasses/contacts, hygiene | Refill prescriptions before storms. |
| Home | Tarps, tape, tools, gloves, garbage bags, cleaning supplies | Useful after leaks, debris, or fridge loss. |
| Cash/fuel | Some cash, full tank, charged devices | Card systems and ATMs may be unreliable after a storm. |
Power, water, internet and communications
After a serious storm, the inconvenience usually comes from outages and logistics more than the storm itself. CUC publishes disaster-preparedness and hurricane-tip material for electricity customers, and telecom service can still vary by exact address and network condition. Have a plan for food, refrigeration, devices, remote work, mobile signal, water pressure, and communicating with family or employers overseas.
- Charge phones, laptops, power banks, lights, fans, radios, and medical devices before the storm.
- Use a UPS for router/modem if short outages would interrupt critical communication.
- Save CUC outage, water, telecom, landlord, strata, and repair contacts offline; do not assume you can search for them after an outage.
- Download offline maps, insurance documents, emergency numbers, and key contacts.
- Assume home internet may fail even if mobile data works, or vice versa.
- Set a family check-in plan: who you message, when, and through which apps if networks are slow.
Stay, shelter, or leave: decide early
Most storms do not require evacuation, but every household should know its thresholds. Your decision depends on property strength, flood exposure, medical needs, children, pets, work obligations, transport, and whether you are comfortable handling several days of disruption.
- If your home is low-lying, poorly shuttered, or medically unsuitable, decide early where you would go.
- Know official shelter options and whether pets are accepted before you need them.
- If considering travel off island, monitor flights early; seats can disappear quickly when a major storm threatens.
- Do not wait until airports, roads, or fuel stations are under pressure to make basic decisions.
- Follow official Cayman weather and government guidance rather than social media rumours.
Families, pets and vulnerable household members
Storm prep is more complex with children, pets, elderly relatives, disabilities, chronic health needs, pregnancy, or anxiety. Build your plan around the most vulnerable person or animal in the household, not the healthiest adult.
- Children: prepare comfort items, offline entertainment, snacks, medications, and a calm explanation of the plan.
- Pets: keep carriers, food, medications, vaccination records, leashes, litter, and pet-friendly shelter/boarding options ready.
- Medical needs: keep prescriptions, devices, backup batteries, doctor contacts, and emergency instructions available.
- Pregnancy/newborns: discuss storm timing and hospital access with your medical provider during hurricane season.
- Visitors: if family is visiting during season, make sure travel insurance and storm logistics are understood.
After the storm
The first day after a storm is about safety and documentation. Do not rush outside during the calm of the eye or before authorities say conditions are safe. Floodwater, downed lines, damaged structures, debris, heat, contaminated food, and road hazards can be more dangerous than people expect.
- Check household safety first: injuries, electrical hazards, water intrusion, gas/propane issues, and structural damage.
- Photograph damage before cleanup if an insurance claim may be needed.
- Throw away spoiled food if refrigeration was lost for too long; do not gamble with food poisoning.
- Avoid driving unless necessary; roads may be blocked or hazardous.
- Use generators outdoors only, away from windows and doors. Carbon monoxide is deadly.
When to get your plan reviewed
Most households can prepare with official guidance and a careful checklist. A local review becomes more useful when the move overlaps hurricane season, the property is waterfront or low-lying, the household has children or medical needs, the lease leaves storm responsibilities vague, or insurance and utility responsibilities are unclear.
- Before signing a lease, ask whether shutters, generator rules, emergency repairs, AC failure, water intrusion, contents cover, early termination, and post-storm access are written down.
- Before buying, connect inspection, insurance, strata, financing, and property-resilience questions before conditions are waived.
- If you are arriving between June and November, build storm readiness into the first-week plan rather than treating it as a later household chore.
