Texas Storm and Flood Event Archive

The Texas storm and flood event archive organizes major historical, modern, recent, and current Texas flood and storm events into a practical timeline so people can understand what happened, which regions were affected, what official resources apply, and what cleanup lessons keep repeating. This guide explains what to do first, what cleanup usually involves, what to document, what insurance may ask, and when to open a live chat instead of guessing.

Quick Answer

Texas Storm and Flood Event Archive starts with safety, documentation, water-source identification, cleanup prioritization, drying, and records. In Texas, the right next step depends on whether water came from flooding, stormwater, sewage, a roof opening, plumbing, or an appliance failure.

Documentation Steps

Phase-based navigation

Choose the Right Recovery Phase

Flood cleanup gets easier when the next step matches the phase you are actually in: safety, first-day documentation, cleanup scope, drying, insurance records, or repair and floodplain questions.

Safety to repair path
01Safety and scene control

First 15 minutes

Decide whether the property is safe to enter, keep people away from water with electrical, sewage, gas, or structural concerns, and start a simple written record from a safe place.

02Photos, source notes, and early triage

First 24 hours

Build the damage record before cleanup changes the scene. Separate floodwater, stormwater, sewage, roof leak, plumbing, appliance, and unknown water-source notes.

03Scope, safety, and documentation alignment

Before cleanup

Before materials are removed or drying equipment is placed, confirm the safety picture, water category, property role, rooms affected, and what should be saved for insurance or disaster records.

04Moisture checks and mold-risk control

During drying

Drying is the phase where hidden moisture matters. A room can look better while wall cavities, carpet pad, cabinets, subfloors, crawlspaces, or commercial zones still need verification.

05Cause of loss, photos, receipts, and conversations

Insurance documentation

Texas insurance questions often turn on water source, policy language, flood insurance, exclusions, endorsements, timing, and documentation. Keep the facts separated and written.

06Before rebuild decisions

Repair/floodplain questions

Cleanup and repair are related but not the same decision. In flood-prone areas, local floodplain administrators, permits, substantial-damage rules, or disaster instructions may affect what happens before repairs.

Texas memory layer

Storm Event Archive

A living archive of major Texas flood and storm events: what happened, which regions were affected, official resource links, cleanup lessons, and documentation reminders. This is built for homeowners, renters, landlords, businesses, reporters, operators, and search systems that need Texas context instead of generic storm content.

Texas flooding is regional

Bayous, creeks, rivers, storm drains, dry washes, coastal surge, and frozen pipes behave differently.

Cleanup lessons repeat

The archive turns past events into practical prompts for safety, documentation, drying, mold risk, and insurance conversations.

Official records matter

Each event points to NWS, NHC, FEMA, TDEM, USGS, NASA, local, or state resources where available.

Operating claims stay separate

The archive is historical guidance. It does not imply offices, response times, partnerships, reviews, or completed jobs.

2001 Tropical Storm Allison Houston Flood

A tropical storm does not need hurricane winds to create severe water damage.

2017

2017 Hurricane Harvey Texas Flooding

One named storm can create several causes of water damage that must be documented separately.

2021

2021 Winter Storm Uri Texas Water Damage

A Texas water damage event does not always start with rain; freeze and utility failure can create major interior flooding.

Jun 5, 2001 to Jun 17, 2001

View event detail page
3 official resources

Allison is one of Houston's defining flood events. NHC and NWS records describe a tropical storm that moved slowly near the upper Texas coast and produced extreme rainfall and catastrophic Houston-area flooding.

HoustonHarris CountySoutheast TexasUpper Texas Coast

What happened

  • Allison moved inland over the upper Texas coast and produced extremely heavy rainfall.
  • Bayous, roadways, homes, medical facilities, businesses, and critical infrastructure were heavily affected.
  • The storm's name was retired despite Allison not reaching hurricane strength.

Regions affected

  • Houston
  • Harris County
  • Galveston County
  • Montgomery County
  • Texas Medical Center

Cleanup lessons

  • A tropical storm does not need hurricane winds to create severe water damage.
  • Houston cleanup records should distinguish bayou/rising water from roof, plumbing, and drainage-source water.
  • Medical, commercial, and lower-level spaces need zone maps and equipment records.

Documentation reminders

  • Build room-by-room and zone-by-zone photo records, especially for lower levels and equipment rooms.
  • Save official flood warnings, local emergency notices, and insurer instructions.
  • Document whether water touched contents, medical equipment, stored records, or electrical/mechanical systems.

2 official resources

Tropical Storm Frances showed how a broad Gulf system can produce coastal flooding, inland rainfall, and backwater problems across a wide Texas footprint before moving north.

Middle Texas CoastSoutheast TexasUpper Texas CoastLouisiana border region

What happened

  • Frances formed over the Gulf and made landfall on the central Texas coast.
  • The storm produced heavy rainfall across coastal Texas and Southeast Texas.
  • Coastal flooding and river backwater effects added complexity to cleanup and documentation.

Regions affected

  • Corpus Christi
  • Port Lavaca
  • Victoria
  • Beaumont
  • Port Arthur

Cleanup lessons

  • Coastal flood cleanup should separate rainwater, surge-adjacent water, drainage water, and wind-driven rain.
  • Salt, silt, and standing water can change material decisions and documentation questions.
  • Commercial properties should document exterior water path, inventory, equipment, and cleanup timing.

Documentation reminders

  • Record whether water entered from doors, bays, drains, roof openings, or rising exterior water.
  • Photograph exterior water marks and interior waterlines before cleaning when safe.
  • Keep weather, local emergency, and insurer communications with the damage file.

2 official resources

The October 1998 South Central Texas floods were a watershed-scale event. NWS describes a nearly stationary storm complex along the Balcones Escarpment, major Guadalupe River impacts, and federal disaster declarations across many counties.

San AntonioGuadalupe River basinSouth Central TexasCoastal Bend downstream areas

What happened

  • Moisture from tropical systems and a slow front helped produce extended heavy rainfall.
  • Flooding struck the Guadalupe River corridor, San Antonio metro area, downstream communities, and several river basins.
  • The event caused long-lived repair, rebuilding, and floodplain questions across many communities.

Regions affected

  • San Antonio
  • New Braunfels
  • Seguin
  • Cuero
  • Victoria

Cleanup lessons

  • Flood waves can affect downstream communities even after rain stops upstream.
  • Permanent repair decisions may need floodplain administrator input in flood-prone areas.
  • Homes rebuilt after prior floods should keep mitigation, elevation, permit, and repair records together.

Documentation reminders

  • Keep photos of flood elevations, debris lines, structural movement, and foundation concerns.
  • Save local floodplain, permit, and substantial-damage communications.
  • Document contents separately from building materials and exterior damage.

Urban creek flash flooding

1981 Austin Memorial Day Flood

May 24, 1981 to May 25, 1981

View event detail page
2 official resources

Austin's 1981 Memorial Day flood remains a core local flood memory. USGS and Austin-area records frame it as a fast urban creek event that changed how the city thinks about flood gauges, low-water crossings, creek corridors, and warnings.

AustinCentral TexasShoal Creek and urban creeks

What happened

  • Heavy rain over the Austin urban core caused rapid creek flooding during Memorial Day weekend.
  • Shoal Creek and nearby low-lying urban areas were heavily affected.
  • The event became a reference point for Austin flood mitigation, gauges, and public warning conversations.

Regions affected

  • Austin
  • Travis County
  • Shoal Creek corridor

Cleanup lessons

  • Urban creeks can rise quickly even when the flooded area is not a wide river valley.
  • Small businesses need inventory, equipment, and interruption records after creek flooding.
  • Older urban properties may need wall-cavity, flooring, and foundation-adjacent moisture checks.

Documentation reminders

  • Photograph waterline height, exterior creek debris, interior affected rooms, and inventory before disposal when safe.
  • Save city or watershed notices that explain access, road closures, or creek warnings.
  • For businesses, separate building, contents, equipment, and reopening records.

Tropical storm remnants and Hill Country flash flooding

1978 Tropical Storm Amelia Hill Country Flood

Jul 30, 1978 to Aug 5, 1978

View event detail page
2 official resources

The remnants of Tropical Storm Amelia became a major Hill Country flood lesson. WPC and USGS records connect the event to severe flooding, rapid runoff, and streamflow records after a weak tropical system moved inland.

Hill CountryCentral TexasNorth Central Texas

What happened

  • A weak tropical storm made landfall near the lower Texas coast, then its remnants produced intense inland rainfall.
  • Hill Country terrain and creek systems amplified runoff and produced deadly flash flooding.
  • USGS later documented central Texas flood data tied to the event.

Regions affected

  • Medina
  • Bandera
  • Kerr County area
  • Austin region
  • Brazos basin

Cleanup lessons

  • A weak tropical storm can still create a major inland flood if rainfall stalls over steep terrain.
  • Low-water crossings and creekside structures need a safety-first reentry mindset.
  • Cabins, short-term rentals, and rural homes should document access roads and exterior debris fields.

Documentation reminders

  • Keep photos of low-water crossings, creek debris, and foundation exposure.
  • Record access limitations if cleanup or inspection was delayed by washed-out roads.
  • Track local official instructions before permanent repairs near waterways.

1 official resources

Hurricane Alice produced a severe Rio Grande flood during a drought period. NWS history describes extraordinary river crests, heavy rainfall around Pandale, and major impacts from the Pecos River to border communities.

Rio GrandeSouth TexasWest TexasBorder communities

What happened

  • The storm moved up the Rio Grande region and produced extreme river flooding.
  • Flooding affected border communities and tributary watersheds, including areas around Del Rio, Eagle Pass, Laredo, and Ozona.
  • The flood became part of the long record used to understand Rio Grande and tributary flood risk.

Regions affected

  • Del Rio
  • Eagle Pass
  • Laredo
  • Ozona
  • Comstock

Cleanup lessons

  • Drought does not remove flood risk; dry channels can become destructive when tropical moisture arrives.
  • River flooding can arrive as a downstream crest after rainfall ends upstream.
  • Border and rural communities may need extra documentation around access, roads, utilities, and timing.

Documentation reminders

  • Record river crest timing and upstream/downstream official notices.
  • Keep photos of sediment, debris, bridge access, and exterior waterlines.
  • Separate floodwater damage from roof, plumbing, or appliance water when documenting interiors.

Remnant tropical cyclone and flash flooding

1921 Central Texas, Thrall, and San Antonio Flood

Sep 8, 1921 to Sep 10, 1921

View event detail page
2 official resources

The 1921 flood is one of the defining events in Texas flood memory. NWS and USGS records describe extreme rainfall from San Antonio north toward Williamson County, including the famous Thrall rainfall record and deadly overnight flooding.

Central TexasSan AntonioWilliamson CountyTaylor and Thrall area

What happened

  • A tropical system moved inland from Mexico and helped produce intense rainfall over South Central Texas.
  • San Antonio experienced destructive flooding along the San Antonio River, and the Thrall area recorded extreme short-duration rainfall.
  • The event shaped future flood-control decisions, including San Antonio's flood-retention infrastructure.

Regions affected

  • San Antonio
  • Thrall
  • Taylor
  • Williamson County
  • Travis County

Cleanup lessons

  • Hill Country and Balcones Escarpment storms can become dangerous faster than surface water clues suggest.
  • Nighttime flash flooding leaves little time for documentation; safety and evacuation warnings come first.
  • Flood history matters when evaluating creek, river, low-water crossing, and floodplain exposure.

Documentation reminders

  • Document high-water marks, debris lines, and water paths when safe after the event.
  • Keep local official instructions and floodplain records with repair documents.
  • Record whether damage came from river rise, creek overflow, drainage, or roof/plumbing sources.

How to use the archive

Turn Texas history into better cleanup decisions

This timeline is not here for disaster spectacle. It helps Texans recognize patterns: Hill Country water rises fast, Houston bayous and drainage can overwhelm slab homes, coastal storms can mix wind and water, South Texas heat complicates drying, East Texas rural properties need access notes, and freeze events can produce interior water damage without rain.

Compare your region to past events before assuming the source of water.Use official links to preserve the disaster context, declaration, or weather record.Document before cleanup when safe, then keep a timeline as rooms change.Separate floodwater, roof water, plumbing water, sewage, contents, and business interruption.Use chat or the recovery toolkit when the damage summary needs structure.
Archive method

Event summaries are written from official and high-quality public resources where available. They do not claim TexasFloodCleanup.com performed work during any event, had crews in the area, or has an office in any affected city. Current entries should be expanded as official after-action reports, disaster pages, county records, and NWS summaries mature.

FAQ

What should I do first after floodwater enters a Texas home or business?

Start with safety. Stay out if there is standing water near electricity, structural damage, gas odor, sewage, chemical contamination, unstable flooring, or local warnings. If it is safe to enter, document damage with photos and video before moving items, then begin water removal and drying or start a live chat to describe the damage.

Does homeowners insurance cover flood cleanup in Texas?

Coverage depends on the policy and the source of water. Texas Department of Insurance guidance says standard home policies generally do not cover flood damage from rising water and that flood insurance is separate. Sudden accidental plumbing water, roof-openings from covered wind damage, sewer backups, and mold may be handled differently depending on endorsements and exclusions.

How quickly can mold become a concern after flooding?

Mold risk can develop quickly when wet materials remain damp, especially in Texas humidity. The practical goal is to remove standing water, expose wet materials, reduce indoor humidity, and verify drying as soon as conditions are safe. No site can guarantee mold prevention, especially after contaminated water or delayed drying.

Is sewage backup cleanup safe to do myself?

Sewage and black water can contain pathogens and other contaminants. Avoid contact, keep children and pets away, and do not use electrical equipment in wet contaminated areas. Large or contaminated losses usually require professional cleanup, controlled removal, cleaning, disinfection, drying, and documentation.

Can cleanup start before an insurance adjuster sees the property?

You should follow your policy, adjuster, FEMA, TDEM, and local instructions, but many official recovery resources emphasize documenting damage and taking reasonable steps to prevent additional damage when it is safe. Take photos and videos first, keep samples or lists when requested, separate damaged and undamaged items, and save receipts.
