Edinburg's Mix of Downpours, Heat and Rare Hard Freezes
Edinburg is the county seat of Hidalgo County and home to the main campus of the University of Texas Rio Grande Valley. It sits about 95 feet above sea level, bordered by Pharr to the south and McAllen to the southwest, on the same flat ground that covers most of the Valley.
Average rainfall is only about 24.06 inches a year, and September is the wettest month at roughly 4.28 inches. Long dry spells are normal. The trouble comes when a big storm dumps several inches in a few hours and the city's stormwater system and the county's drainage ditches fall behind.
Edinburg also holds a cold-weather record many people forget: its all-time low of 20 degrees came on February 16, 2021. Between flash floods, tropical storms and that kind of freeze, water damage in Edinburg can come from almost any direction.
When the Valley Froze in February 2021
The National Weather Service described the February 2021 arctic outbreak as the most intense to hit the region, by cold and duration, since December 1989, and the first widespread killing freeze in the Valley since then. Record lows were set across the area, and the NWS noted an unknown number of water main and pipe bursts.
Many homes here were built with heat in mind, not ice. Supply lines in attics, outside walls and unheated garages are the most likely to split. Often the leak doesn't show until temperatures rise and the water starts moving again.
- Before a hard freeze, wrap exposed pipes and outdoor faucets and let indoor faucets drip.
- Open cabinet doors under sinks on outside walls.
- Learn where the main shutoff is and make sure it turns.
If a pipe does burst, shut the main and call (888) 817-5061 to be connected with a local provider for water extraction and drying.
Downtown Flooding and the County Drainage System
During the Great June Flood of 2018, a gauge near Edinburg measured 10.16 inches, and the National Weather Service reported 2 feet of standing water at West University Drive and South 10th Avenue in downtown Edinburg. Nearby, the NWS estimated at least 2,700 homes and businesses flooded in Mission and McAllen during the same storm, so the whole area felt it.
Hidalgo County Drainage District No. 1, based in Edinburg, manages the county's master drainage system and publishes a floodzone map. The City of Edinburg's Engineering Department runs a floodplain management program, reviews elevation certificates for new development, and points residents to FEMA's flood maps. You can start with the city's floodplain management page.
To report a city concern such as a clogged street drain, use Edinburg 311. Keeping inlets near your home clear of leaves and trash before a storm also helps water move away faster.
Simple Steps While You Wait for Help
- Protect people first. Avoid any room where water may be touching outlets, cords or appliances.
- Stop new water. Close the main valve for plumbing leaks. For storm water, block doorways with towels or sandbags only if it is safe.
- Identify the water. Clean supply water is Category 1. Water from the street or a drainage ditch is Category 3 and should be handled with gloves and boots.
- Take photos and notes. Capture each room, the source, and the date and time.
- Remove valuables. Move documents, electronics and keepsakes to a dry space.
For flood cleanup in Edinburg after a storm, it helps to have a professional remove soaked materials and sanitize, rather than just mopping.
What Restoration Looks Like in an Edinburg Home
Every job varies, but most local companies work through these stages:
Stop and assess
The crew confirms the source is shut off and uses moisture meters to see how far water spread.
Extract and remove
Standing water is extracted. Wet carpet pad, the lower part of drywall and insulation are often removed after dirty water.
Dry
Commercial dehumidifiers and air movers run for several days while moisture readings are logged. Our structural drying page covers this step.
Rebuild
With dry materials confirmed, water damage repair brings back drywall, paint, flooring and cabinets. Feel free to ask any company for proof of its licensing and insurance and for details on crew training, such as IICRC certification.
Hurricane Rain and Wind 50 Miles Inland
Edinburg is roughly 50 miles from the Gulf, but tropical systems still reach it. When Hurricane Beulah came ashore near the mouth of the Rio Grande in 1967, gusts of more than 100 mph were recorded as far inland as McAllen, Edinburg, Mission and Pharr. In 2020, Hurricane Hanna's rainbands caused flash flood emergencies in nearby McAllen and Mission.
Wind can peel shingles and break windows, letting rain soak attics and walls. Storm damage cleanup typically starts with tarping and board-up, then drying. Hurricane season runs June 1 through November 30.
Mold Licensing, Insurance and Rental Property Notes
Following EPA guidance, mold may appear on materials that stay wet longer than about 24 to 48 hours. In Texas, TDLR licenses mold assessors and remediators, and a license is generally required when mold covers 25 contiguous square feet or more. One company may not both assess and remediate the same project, and a Certificate of Mold Remediation must be issued within 10 days after the work. See mold removal for how containment works.
Insurance usually splits water losses in two. Standard homeowners policies generally exclude flood, which needs an NFIP or private flood policy (NFIP policies typically have a 30-day waiting period). The Texas Attorney General says most Texas homeowner policies cover only sudden and accidental leaks and may cap mold.
Landlords and tenants should both notify the other promptly, since renters insurance and the owner's policy usually cover different things. For homes, apartments or commercial buildings, call (888) 817-5061, available 24/7.

Edinburg Water Damage FAQ
How cold did Edinburg get in the February 2021 freeze?
Edinburg's all-time record low of 20 degrees was set on February 16, 2021. The National Weather Service called it the first widespread killing freeze in the Rio Grande Valley since December 1989, and pipe bursts were reported across the area.
Where can I check flood maps for an Edinburg property?
The City of Edinburg's floodplain management page links to FEMA's Map Service Center, and Hidalgo County Drainage District No. 1 publishes a floodzone map dashboard.
Can I just mop up storm water that came under my door?
Small amounts of clean water can be mopped, but water from streets or ditches is considered contaminated. It soaks into drywall and carpet pad, so those materials usually need removal, sanitizing and professional drying.
What paperwork should I get after mold remediation in Texas?
Ask for the Certificate of Mold Remediation, which must be issued within 10 days after the work. Keep it with your property records, since sellers must give buyers copies.
