Hurricane season on the upper Texas coast rewards the households that decided things early — the zone, the route, the kit, the coverage. Here's the complete Bay Area preparedness guide, including the insurance moves that only work before a storm has a name, from a licensed agency in Pearland.
Bay Area hurricane readiness comes down to four decisions made before a storm has a name. Know your evacuation zip zone — the Houston-Galveston region divides Brazoria, Chambers, Galveston, Harris, and Matagorda counties into zones Coastal, A, B, and C, which evacuate in that order; evacuate from surge if your zone is ordered out, shelter from wind if it isn't. Build a 3-day supply kit and set your destination and route early. And make the insurance moves with deadlines: flood coverage typically has a 30-day NFIP wait, insurers commonly stop writing new coverage once a storm is named, and your wind, home, and flood deductibles should be calculated in real dollars now — not discovered after landfall.
Every Bay Area household that has been through a hurricane knows the difference between the families who decided things in May and the ones deciding at midnight with a storm twelve hours out. The zone, the route, the kit, the coverage — none of it is complicated. All of it has a deadline.
We're a licensed insurance agency in Pearland, and this is the guide we wish every household in Brazoria, Galveston, and southeast Harris County had on the refrigerator. It covers the evacuation zone system and how to find yours, the leave-or-stay decision, the plan and the kit, the insurance moves that only work before a storm has a name, how to document your home, and what to do during and after a storm. Preparedness guidance here draws on the Houston-Galveston Area Council, the National Weather Service, and local emergency management; confirm current orders and maps with officials when a storm actually threatens.
What's Your Evacuation Zone?
The short answer: the region evacuates by zip zone — Coastal, then A, then B, then C — and you should know yours today.
The Houston-Galveston region runs hurricane evacuations on a zip-code-based zone system covering Brazoria, Chambers, Galveston, Harris, and Matagorda counties, maintained by the Houston-Galveston Area Council. Per H-GAC, the four zones track storm surge risk and evacuate in priority order:
| Zone | Risk level | Evacuation order |
|---|---|---|
| Coastal | Highest surge risk, closest to open water — all of Galveston Island is Zone Coastal | First |
| A | High surge and flooding risk | After Coastal |
| B | Moderate risk with serious flood potential | After A |
| C | Lower-risk inland areas; may still evacuate in a major direct hit | Last |
Per the Houston-Galveston Area Council zip-zone system. Some zip codes are split north/south for evacuation purposes — check your specific address, and make sure the map you save is the current year's.
Look your address up on H-GAC's zip-zone map at h-gac.com/hurricane, save a copy, and make sure everyone in the household knows the zone. Much of the inland Bay Area — including large parts of Pearland — sits in the later zones or outside them entirely, while communities closer to Galveston Bay carry earlier designations. The point of knowing now: when orders start rolling zone by zone, you'll know immediately whether they mean you.
When Do You Evacuate — and When Do You Stay?
The short answer: evacuate from water when your zone is ordered out; shelter from wind when it isn't.
The organizing principle emergency managers teach is simple: run from water, hide from wind. Storm surge is the hazard the zone system exists for — if officials order your zone to evacuate, that's the signal to go, early and calmly, inland along the designated routes. If your zone is not ordered out, the general guidance is to prepare to shelter in place rather than joining the highway. This region learned that lesson hard: Hurricane Rita in 2005 triggered the largest pre-storm evacuation in Texas history — millions of residents — and the gridlock itself became dangerous. The zone system exists precisely so the people facing surge can get out first.
The practical rules that make either choice work, per TxDOT and local officials: never let your tank drop below half during hurricane season; decide your destination and route before June, and book lodging early if a storm threatens; and monitor official sources — local emergency management, the National Weather Service — rather than rumor. Hurricanes also bring more than surge and wind: NWS hazard guidance covers inland flooding from rain, tornadoes in the outer bands, and dangerous surf, which is why even well-inland households need a plan.
What Goes in the Plan and the Kit?
The short answer: three days of self-sufficiency, documents included — built in May, not at midnight.
Regional guidance from H-GAC calls for an emergency kit covering at least three days:
- Water — a gallon per person per day — and non-perishable food
- Medications, first aid supplies, and anything medically essential
- Light and information — flashlights, batteries, a battery or hand-crank radio, charged backup power for phones
- Cash — card systems fail when power does
- Documents — copies of IDs, insurance policies, and your agent's contact information in a waterproof container
- The rest of the household — pet food, carriers, and a pet-friendly destination; supplies for infants and family members with medical or mobility needs
The plan is the other half: where you'd go in an evacuation, which route, who picks up the kids, how the family regroups if separated, and who the out-of-area contact is. Write it down. The households that manage storms well aren't calmer by temperament — they just already decided.
The Insurance Moves to Make Before June
The short answer: four moves with real deadlines — flood, wind, deductibles, and documentation.
This is the part of hurricane prep that quietly has the earliest deadline, because coverage can't be bought when it's needed most:
- Confirm your flood coverage. No homeowners policy covers flood, and new NFIP policies typically carry a 30-day waiting period — coverage bought in early June protects the season's peak; coverage attempted during a storm threat protects nothing. Our Texas flood insurance guide covers the options.
- Know which policy carries your wind. Across the Bay Area's coastal counties, homeowners policies often exclude wind, with coverage written separately through TWIA or a private insurer. Find the policy, confirm it's in force, and check the limits — our windstorm guide explains the system.
- Calculate every deductible in dollars. Wind deductibles typically run 1–5% of your dwelling limit, and after a hurricane your wind, homeowners, and flood deductibles can each apply to their own claim. Add them up now — the total is the number your emergency fund should know about.
- Mind the moratorium. Insurers commonly suspend new policies and coverage changes once a named storm enters or approaches the Gulf. Every coverage decision has an effective deadline you won't see announced in advance.
One more for coastal homeowners: if you've had a roof replaced or an addition built, confirm your windstorm certificates are in order before you need your windstorm coverage to respond or renew smoothly.
How Do You Document Your Home Before the Season?
The short answer: a 15-minute video walkthrough, stored in the cloud, plus your policy documents.
After a major storm, the single most valuable thing a policyholder can have is proof of what the home looked like before. The pre-season version takes fifteen minutes:
- Video walkthrough — every room, opening closets and drawers, narrating as you go; then the exterior, roof line, fence, and any outbuildings
- Close-ups of valuables — electronics, jewelry, tools, appliances, with serial numbers where practical
- Store it off-site — cloud storage, not just your phone; a phone can be in the same flood as the house
- Copies of declarations pages for every policy — home, wind, flood, auto — with your agent's contact info, in the kit and in the cloud
Update it annually and after any major purchase or renovation. This one habit shortens and strengthens every claim you might ever file.
What Do You Do During and After the Storm?
The short answer: safety, then documentation, then prompt reporting — and healthy skepticism toward whoever knocks first.
During: shelter in an interior room away from windows, keep the radio on, stay inside through the eye — the back half arrives fast, from the other direction. After: return or emerge only when officials say it's safe; downed lines, gas leaks, and weakened structures injure people after the wind stops.
Then the claim sequence that protects you:
- Photograph and video all damage before touching anything — wide shots and close-ups, inside and out
- Make only temporary repairs needed to prevent further damage — tarping, board-up — and keep every receipt
- Report promptly to each relevant insurer. Wind and flood damage from the same storm go to different policies; our wind vs. flood guide explains how that allocation works and how to document for it
- Be careful with post-storm contractors. Verify credentials and local references, insist on written estimates, and be cautious about signing anything that assigns your claim or benefits before you've talked to your insurer or agent
The Bay Area Picture: Pearland, League City, Friendswood & Alvin
The short answer: our corner of the region mixes inland-coastal quirks — windstorm territory, creek flooding, and zone lines that surprise people.
The Bay Area's hurricane exposure isn't uniform, and the local details matter. Pearland sits well inland but inside first-tier Brazoria County — windstorm territory — with Clear Creek flooding as its signature water risk. League City straddles higher flood exposure along Clear Creek and Dickinson Bayou, with parts of the city in earlier evacuation zones. Friendswood and Alvin share versions of the same mix. Across all of them, the same three-policy structure applies: a homeowners policy that likely excludes wind, a separate windstorm policy, and flood coverage that no home policy includes.
Our local guides go street-level on the risk: Pearland flood insurance, the League City insurance guide, and the coastal home insurance guide for the full three-policy picture. Friendswood and Alvin guides are coming as this series grows.
The Bottom Line on Bay Area Hurricane Prep
Here's the whole thing in a few sentences. Look up your evacuation zip zone today — the region evacuates Coastal, then A, then B, then C, and knowing your zone is what turns official orders into a clear personal instruction. Evacuate from surge when your zone is called; shelter from wind when it isn't; keep the tank above half all season. Build the three-day kit and write the plan in May. And make the insurance moves while they're still possible: flood coverage with its 30-day wait, clarity on which policy carries your wind, every deductible calculated in dollars, and a video walkthrough of your home sitting safely in the cloud — because once a storm is named, insurers generally stop writing, and preparation time is over.
The insurance half of that list is a thirty-minute review, and it's what we do all season from right here in Pearland. We'll confirm your flood and wind coverage, size the limits, total your real deductible exposure, and flag any gaps while there's still time to close them — free, no obligation, and far more useful in June than in September.
Frequently Asked Questions
The Houston-Galveston region uses a zip-code-based evacuation system covering Brazoria, Chambers, Galveston, Harris, and Matagorda counties, with four zones: Coastal, A, B, and C. Zone Coastal covers the highest-risk areas closest to open water — all of Galveston Island is in the Coastal zone — and evacuates first. Zone A follows, then B, then C, in order of storm surge risk. Some zip codes are split north and south for evacuation purposes. Your zone determines when you'd be ordered to leave, so looking it up on the H-GAC zip-zone map before the season — and saving it — is the single most useful five-minute prep task.
The guiding principle: evacuate from water, shelter from wind. Storm surge is the deadliest hurricane hazard, so if officials order your zone to evacuate, you leave — that's what the zone system exists for. If you're not in an ordered zone, the general guidance is to prepare to shelter in place rather than joining evacuation traffic, which historically has created its own dangers in this region. Monitor official orders through local emergency management and the National Weather Service, decide your destination and route before the season, and never let your vehicle drop below half a tank during hurricane season.
Supplies for at least three days of self-sufficiency: non-perishable food, one gallon of water per person per day, medications, flashlights and batteries, a battery or hand-crank radio, phone chargers and backup power, cash, first aid supplies, and copies of important documents — including your insurance policies and agent contact information — in a waterproof container. Plan separately for pets, infants, and family members with medical or mobility needs. Build the kit in May, not when a storm is in the Gulf and shelves are empty.
Four moves, all with deadlines. Confirm your flood coverage — no homeowners policy covers flood, and new NFIP policies typically carry a 30-day waiting period. Know which policy carries your wind, since Bay Area homeowners policies often exclude wind in favor of a separate windstorm policy. Calculate every deductible in dollars — wind, homeowners, and flood — so the totals aren't a surprise. And document your home with a video walkthrough stored in the cloud. Insurers commonly suspend new coverage once a named storm approaches, which is why all of this has to happen in advance.
Safety first — return only when officials say it's safe, watching for downed lines, gas leaks, and structural damage. Then document before you clean: photograph and video all damage thoroughly before removing anything. Make only the temporary repairs needed to prevent further damage, keep receipts for everything, and report claims promptly to each relevant insurer — wind and flood damage may go to different policies. Be cautious with door-to-door contractors: verify credentials, get written estimates, and be careful about signing documents that transfer control of your claim before talking to your insurer or agent.
