One year ago this week, the Rio Grande Valley suffered a torrential onslaught the likes of which are not normally seen outside a hurricane.

The rain event spanned several days, from June 18-22, and affected not just the Valley, but parts of the Coastal Bend, as well. It seemed as if the storm cells chose a different city every day upon which to unleash their worst.

The Mid-Valley — in particular, Weslaco — was the hardest hit, with some 16-18 inches of rain pummeling the city over the course of a few hours, according to estimates by the National Weather Service.

At one point, a rain gauge located at the Mid Valley Airport reported 11.36 inches of rainfall in three hours.

Beginning this week, the newspapers of AIM Media Texas — the Mid-Valley Town Crier, The Monitor, and the Valley Morning Star — will be examining the effects of what the NWS ultimately dubbed The Great June Flood of 2018 in the RGV.

On this, the one year anniversary of the storm, we’ll look at what happened in its aftermath — on scales both large and small.

We’ll look back at FEMA’s decision to deny flood relief, as well as the passage, locally, of several multimillion dollar drainage improvement bonds.

And in next week’s edition of the Crier, we’ll take a more intimate glimpse of how the flood affected one Weslaco family, who watched as a drainage canal behind their home failed — one of many throughout the city to do so — ultimately destroying their home and those of their neighbors.
