Severe storms swept through North Texas on Tuesday morning, May 6, 2025, leaving a trail of destruction and thousands of homes without electricity. Strong winds, hail, and heavy rain toppled trees, damaged power lines, and disrupted daily life in cities like Dallas, Irving, and McKinney. Oncor, the region’s power provider, reported over 300,000 customers affected at the storm’s peak. The impact hit schools, hospitals, and businesses, with authorities warning of potential further storms.
Warning sirens blared before dawn in several cities as wind gusts up to 80 km/h tore off roofs and scattered debris across streets. In Dallas, heavy rain combined with winds caused flooding in urban areas, complicating traffic and repair efforts. Emergency crews responded swiftly, prioritizing public safety and the restoration of essential services.
Dallas County was the hardest hit, with about 160,000 customers without power by noon on Tuesday. Other counties, such as Collin, Tarrant, and Denton, also faced significant outages, with 30,000 to 70,000 homes affected in each. Below are the main impacts of the storms:
- Widespread blackouts: Over 300,000 Oncor customers lost power, with Dallas and Collin among the most affected.
- Structural damage: Fallen trees, broken poles, and damaged roofs were reported across multiple cities.
- Traffic disruptions: Flooding and debris blocked roads, hindering travel.
- Flight cancellations: Airports like Dallas-Fort Worth and Love Field saw delays and cancellations.
Local authorities issued safety alerts, urging residents to avoid areas with downed power lines and stay home if possible. The forecast of more rain Tuesday night raised concerns about delays in power restoration.
Damage in Dallas and surrounding areas
Dallas bore the brunt of the damage, with the county reporting significant harm to homes, schools, and commercial infrastructure. In Irving, an EF1 tornado was confirmed, leaving power poles snapped and debris strewn across streets. Fallen trees blocked major roads like North O’Connor Road, forcing school closures, including Lorenzo de Zavala Middle School, due to damaged power lines and nearby gas leaks.
In McKinney, the Collin County Sheriff’s Office reported damage to vehicles and structures, with winds toppling trees onto public properties. While no fatalities were recorded, the extent of material damage is still being assessed. Oncor crews began work immediately, but the company warned that repairs in heavily impacted areas like Irving and Farmers Branch could take until Friday.
The combination of strong winds and heavy rain also caused flooding in low-lying Dallas areas. Interstate 635 was partially closed due to water accumulation, and drivers were advised to avoid unnecessary travel. In some regions, visibility was reduced by dust stirred up by the winds, further complicating restoration efforts.

Impact on essential services
Hospitals and healthcare facilities in North Texas operated on emergency generators while power remained out. Oncor prioritized reconnecting critical infrastructure, such as medical centers and water pumping stations, to prevent disruptions in water supply. Fortunately, all water treatment plants remained operational, ensuring potable water availability.
Schools in several districts, such as DeSoto ISD, canceled classes due to power outages in over half their facilities. Other institutions, like St. Elizabeth Ann Seton Church in Plano, maintained scheduled activities, such as Ash Wednesday masses, despite the blackouts. The Dallas diocese confirmed Oncor was on-site to expedite repairs.
- School closures: Districts like DeSoto and Irving suspended classes due to lack of electricity.
- Emergency services: Firefighters and police increased patrols to monitor affected areas.
- Public transport: School buses faced delays due to blocked roads and inoperative traffic lights.
The outages also disrupted Dallas’ primary runoff elections, with over a third of polling stations without power. The county extended voting hours until 9 p.m. to accommodate affected voters.
Power restoration efforts
Oncor mobilized hundreds of workers, including crews from other states, to speed up power restoration. However, the company faced challenges due to the extent of the damage and ongoing adverse weather. Persistent winds throughout the day hindered crews, especially in areas with downed lines and accumulated debris.
In a statement, Oncor reported that most customers would have power restored by Thursday evening, but areas like McKinney and Irving might see full repairs only by Friday. The company also urged residents to inspect their meters and home wiring, as damage to these requires electrician repairs before reconnection.
To report outages, Oncor provided multiple channels, including the MyOncor app, the 888-313-4747 hotline, and texting “OUT” to 66267. The company emphasized the importance of staying away from downed power lines, warning that even tree branches in contact with wires could be energized.
History of Texas blackouts
North Texas is no stranger to storm-related power outages. In May 2024, hurricane-force winds left over 600,000 customers without power in Dallas and surrounding areas, with repairs taking days. Similar events occurred in 2023, when an ice storm in Austin toppled trees onto power lines, affecting 170,000 people.
The February 2021 Winter Storm Uri remains the state’s worst power crisis. Over 4.5 million homes and businesses lost electricity, and at least 246 people died due to infrastructure failures. The lack of preparation for extreme cold exposed the Texas grid’s vulnerabilities, which have not been fully addressed since.
- 2021 storm: Left millions without power and exposed grid weaknesses.
- May 2024: Winds up to 100 km/h caused outages in Dallas and Houston.
- 2023: Ice storm in Austin resulted in 170,000 customers without power.
These events sparked debates about modernizing the power grid, but the high costs of upgrades, such as replacing wooden poles with steel structures, remain a barrier.
Forecast for new storms
The National Weather Service (NWS) issued severe thunderstorm warnings for North Texas until 10 a.m. Tuesday, with the possibility of additional storms Tuesday night. Forecasts indicate winds up to 75 km/h, hail up to 2.5 cm, and risks of localized flooding. The Dallas-Fort Worth area is particularly vulnerable, with soil already saturated from recent rains.
Wednesday is expected to bring a temporary reprieve, but another round of storms could arrive Thursday night, bringing hail, strong winds, and heavy rain. Authorities recommended that residents prepare emergency kits with flashlights, batteries, and non-perishable food and avoid flood-prone areas.
Public safety measures
Public safety was the priority during and after the storms. Rescue teams patrolled affected areas, and the Dallas Fire Department responded to calls about gas leaks and structural damage. In Irving, residents of the Tree Country apartment complex were evacuated due to risks from damaged power lines.
Authorities also opened cooling centers in cities like Dallas and Fort Worth, providing shelter for those without power amid temperatures around 30°C. The guidance was clear: avoid contact with debris near power lines and report issues immediately to authorities.
- Cooling centers: Available at gyms and community centers.
- Avoiding risks: Residents were urged not to touch downed wires or branches.
- Emergency support: Lines like 911 and Oncor’s hotline received thousands of calls.
Dallas Police increased patrols to prevent looting in areas without power, while volunteers distributed water and food in heavily affected communities.
Damage to commercial infrastructure
Beyond homes, businesses and commercial facilities sustained significant damage. In Lewisville, the Benjamin Moore Paints distribution center had part of its roof destroyed, halting operations. In Carrollton, small aircraft at Air Park-Dallas were damaged by winds, and a trampoline was found lodged in a tree.
In retail, stores like Walmart reported damage from hail, with broken skylights and merchandise exposed to rain. Recovery for these facilities may take weeks, especially in areas where electrical repairs are prioritized.
Impact on air travel
The region’s airports faced significant disruptions. At Dallas-Fort Worth International Airport, about 300 flights were delayed and 250 canceled by 9 a.m. Tuesday. Love Field in Dallas reported 68 delays and 63 cancellations in the same period. The storms forced a temporary halt to takeoffs, affecting thousands of passengers.
Airlines offered no-cost rebookings, but full operations depend on weather stabilization. Passengers were advised to check flight statuses before heading to airports.
Lessons from past events
The 2025 storms underscore the need to prepare Texas’ electrical infrastructure for extreme weather. After the 2021 crisis, the Federal Energy Regulatory Commission recommended grid modernization, including replacing wooden poles with more resilient materials and expanding tree-trimming programs near power lines. However, the high costs of these measures have limited their implementation.
In 2024, Oncor announced a $3 billion investment plan to reinforce poles, replace aging cables, and install underground lines in some areas. About $285 million of this budget will fund vegetation management, using satellite imagery to identify at-risk trees. Despite these efforts, the increasing frequency of severe storms continues to challenge the state’s response capacity.
