Severe Weather in Houston

A Snapshot of May Hail and Flooding

By Tom Larsen Natural Hazard, Real Estate

Texas is no stranger to extreme weather events.

In 2015 on Memorial Day, Houston was inundated with a foot of rainfall. Two years later, and Hurricane Harvey stalled out, causing massive amounts of rainfall induced flooding. The storm put the metropolitan area, with a population of nearly 7 million people underwater, concrete-laden streets becoming bonafide rivers. CoreLogic® found that 70% of the flood damage from the hurricane was uninsured.

In 2018, in the early morning hours of June 6, baseball sized hail struck the middle of the Dallas-Fort Worth metro area, causing damage upwards of $1 billion, making it the third costliest hailstorm in Texas History.

2019 proved itself to be no different. Houston was once again impacted by catastrophic flooding and hail during the first full week of May. Defining the southern edge of a large weather front on May 9 across the U.S. Southeast, severe thunderstorms forecasted for Houston delivered hailstorms in many neighborhoods.

Impact of Hail on Homes in Houston

From hail alone, Reactor™ from CoreLogic estimated that more than 50,000 homes were exposed to golf ball-sized hail or greater, causing damage to roofs in a region already beset by heavy rainfall and localized flooding.

More than 12” of rainfall in some areas over the course of a week have led to widespread flash-flooding in low-lying areas.

Weather radars can observe the whole storm, but different combinations of rain and hail sizes can look identical. The proprietary hail verification science from CoreLogic enables a better estimate of the effects of the damaging hail.
