If you own or rent a home on Galveston Island, the question is not whether a storm will threaten, but when. This guide walks you through what to do before the season and in the days before a storm makes the coast, so you protect both your safety and your property. You will finish with a clear checklist and know exactly where your weak points are.
Know Your Evacuation Zone and Trigger
Galveston sits on a barrier island. Water, not wind, is the biggest killer in most storms. Long before a threat forms, find out which evacuation zone you live in through the City of Galveston Office of Emergency Management and the Texas coastal evacuation maps.
Decide your personal trigger in advance. Many island residents leave when a voluntary evacuation is announced rather than waiting for a mandatory one, because bridge and I-45 traffic backs up fast. If you have pets, medical needs, or no vehicle, plan those details now, not during a rush.
Protect the Building Envelope
Your roof, windows, and doors are the shell that keeps wind and rain out. Once that shell fails, interior damage multiplies.
Windows and doors
Permanent storm shutters or pre-cut plywood panels give real protection. Tape does nothing useful and creates dangerous shards. Reinforce garage doors, which are a common failure point in high wind.
Roof and yard
Have loose or aging shingles repaired before the season. Trim dead branches. In the days before a storm, bring in or tie down anything that can become a projectile: patio furniture, grills, planters, and trash bins.
Flood Readiness Inside the Home
Assume water can enter. Move valuables, electronics, and irreplaceable items to a higher floor or high shelves. If you have time, raise appliances and disconnect power to areas likely to flood. Keep sandbags for door gaps, but understand they slow water, not stop it.
Documents, Power, and Supplies
Keep insurance policies, IDs, deeds, and medical records in a waterproof container or a secure cloud account you can reach from a phone. Photograph every room before the season for insurance proof of condition.
Build a supply kit that lasts at least three to seven days: water, non-perishable food, medications, flashlights, batteries, a battery or crank radio, and cash. ATMs and card readers fail when power does.
A Real Scenario
Consider a family in the East End who waited for a mandatory order during a fast-moving storm. They left with a full tank but hit standstill traffic on the causeway for hours. A neighbor who left the day before, on the voluntary notice, was already inland and safe. Same storm, very different night. The lesson is simple: leaving early costs you a little inconvenience; leaving late can cost far more.
Common Mistakes and How to Fix Them
- Waiting for the mandatory order. Fix: set your own earlier trigger and stick to it.
- Assuming a standard homeowners policy covers flood. Fix: it usually does not; confirm separate flood coverage well ahead of time.
- Taping windows instead of shuttering. Fix: use shutters or plywood panels cut and labeled in advance.
- Relying only on a phone for records. Fix: keep waterproof paper copies too, since networks and charging fail.
- Forgetting pets and neighbors. Fix: confirm pet-friendly shelter options and check on older or isolated residents nearby.
Your Pre-Storm Checklist
- Confirm your evacuation zone and two routes off the island.
- Fill your gas tank and withdraw cash when a storm enters the Gulf.
- Install shutters or panels; secure the garage door.
- Move valuables up; photograph each room.
- Pack a three-to-seven-day supply kit and a go-bag.
- Charge devices and battery banks.
- Back up documents to waterproof storage and the cloud.
- Leave early once your personal trigger is met.
Conclusion and Next Step
Preparation is mostly decisions made in calm weather. Your single most valuable next step: look up your evacuation zone today and write down the exact conditions under which you will leave. Everything else follows from that one choice.
Frequently Asked Questions
When should I evacuate from Galveston?
Do not wait for the last order. Set a personal trigger, such as a voluntary evacuation notice, and leave then to avoid gridlock on the causeway and I-45.
Does homeowners insurance cover hurricane flooding?
Typically no. Flood damage usually requires a separate flood policy, and new coverage often takes effect only after a waiting period, so arrange it long before a storm.
Is plywood or tape better for windows?
Plywood panels or rated storm shutters protect the glass. Tape does not prevent breakage and can create larger, sharper fragments.
How much water and food should I store?
Plan for at least three days, and ideally up to a week, since power and resupply can be slow after a major storm.
