Why the Rio Grande Valley Flooded Again


For hundreds of residents in the Rio Grande Valley, it’s like Déjà vu, cars stranded on roads, homes flooded with water, property damaged, roads inaccessible and citizens overwhelmed.

Estimated peak winds from 65 to 75 mph, and at least 12 inches of rain falling in some areas resulted in snapping large

tree limbs, uprooting trees, metal towers collapsing, mobile homes destroyed and wooden power poles snapping.

However, although this week’s weather seems very similar to the June Floods of 2018, the National Weather Service explains how it’s not.

What happened is we had a thunderstorm complex that was driving south through Houston and through Galveston and then ultimately off the coast of the Coastal Bend,” said Berry Goldsmith, Meteorologist with the National Weather Service.

“And at the same time it set off a boundary that produced a pretty big thunderstorm in Kingsville and as that storm moved to south into the very rich environment of the hot, humid air that we had for days leading into it, it became what’s called a precipitation supercell,” Goldsmith said.

“The bottom line is last year completely different set up to this one, this one more like what we would see in May,” he added.

This year, Harlingen was likely the top rainfall site with almost 12 inches, last year the top hit area was between Mercedes and Weslaco with potentially 18 inches of rainfall.
