Tropical Storm Arthur 2026: How Gulf Coast Homeowners Can Prevent $35,000 in Flood Damage

Tropical Storm Arthur — the first named storm of the 2026 Atlantic hurricane season — is battering Texas, Louisiana, Mississippi, and Alabama with up to 20 inches of rain and dangerous flash floods. Here's what Gulf Coast homeowners need to know right now.

Where Is Arthur Hitting Right Now?

Arthur made its presence felt across the Gulf Coast on June 17, 2026. The storm is dumping historic rainfall across the Gulf South, with meteorologists warning of life-threatening flash floods through Thursday morning.

Affected zones by severity:

• 🔴 Houston / Galveston, TX
• 🔴 Beaumont / Port Arthur, TX
• 🔴 New Orleans, LA
• 🔴 Baton Rouge / Morgan City, LA
• 🟠 Biloxi / Gulfport, MS
• 🟠 Mobile, AL
• 🟡 Austin / San Antonio, TX
• 🟡 Jackson, MS

Arthur is expected to dissipate by Thursday morning. Flash flood risk remains elevated through Friday across Louisiana, Mississippi, and southwest Alabama.

The Hidden Danger: Your Sliding Glass Doors

During tropical storms, most homeowners focus on windows and garage doors. But the single most vulnerable entry point for floodwater in a typical Gulf Coast home is often overlooked: sliding glass doors.

Standard sliding glass door tracks are designed for rain, not flood surge. Once water levels rise even a few inches, the track seal fails — and floodwater enters your home fast.

FEMA data is clear: just 6 inches of floodwater causes an average of $35,000 in structural and personal property damage. Arthur is forecast to produce up to 20 inches of rainfall in some areas.

What To Do Right Now If You're in the Storm Path

In the next hour:

• Check your local National Weather Service alert for active warnings.
• Move valuables and electronics off the floor, especially near exterior doors.
• Inspect your sliding glass door tracks for debris or existing seal damage.
• If you have a StormArmour barrier, install it now before water begins to rise.

If you don't have a flood barrier:

• Place rolled-up towels or sandbags against the door base as a temporary measure.
• Do not attempt to seal tracks with caulk or tape — these fail quickly under water pressure.
• Document your home's current condition with photos and video for insurance purposes.

After the storm passes:

• Do not enter a flooded room until power is confirmed off.
• Photograph all damage before cleanup for your insurance claim.
• Contact your insurer within 24–48 hours.
• Begin drying and ventilating immediately — mold sets in within 24–48 hours.

Why the Gulf Coast Is Especially Vulnerable

The Gulf of Mexico's warm, shallow waters allow storms to intensify rapidly with little warning. The region's flat coastal geography means surge can push water miles inland even from a modest tropical storm. Louisiana sits below sea level in many areas, and when a system like Arthur stalls, cumulative rainfall quickly overwhelms drainage — and enters homes through every low-lying opening it can find.

"StormArmour gives homeowners real protection when it matters most."

How StormArmour Works

StormArmour is a water intrusion barrier engineered specifically for sliding glass doors — the weak point that standard hurricane shutters leave unprotected. It installs without tools in minutes, creating a watertight seal at the door track.

• Miami-Dade NOA approved — the toughest hurricane-product certification in the U.S.
• No permanent installation — deploy before a storm, remove after.
• Ships directly to you — no home improvement store required.
• $585 — a fraction of the $35,000 average flood damage cost.

Frequently Asked Questions

Does StormArmour work on all sliding glass door sizes?
StormArmour fits the most common residential sliding glass door sizes. Visit stormarmour.com to confirm compatibility before ordering.

How quickly can I install it before a storm?
Most homeowners complete installation in under 10 minutes with no tools required.

Will homeowner's insurance cover flood damage through sliding glass doors?
Standard homeowner's insurance typically does not cover flood damage — you need a separate NFIP or private flood policy. StormArmour prevents the damage before it happens.

How long does Arthur's flood threat last?
The storm dissipates Thursday morning, but flash flood risk remains elevated through Friday. Recovery flooding can persist for several days after.

Can I use StormArmour for future storms too?
Yes — it's a reusable barrier. Install before each storm, store between seasons.
