Coryell County Flood History

Flash Flood — Jun 11, 2025

An upper level low and remnant MCVs produced several rounds of heavy rain and training storms that produced flash flooding for a few day across the region, mainly across Central Texas.

Flash Flood — Jul 7, 2025

From the July 4th weekend into the early part of the following week, a weak upper trough lingered over North and Central Texas, triggering several days of scattered showers and thunderstorms. A saturated atmosphere combined with slow storm motions resulted in numerous flash flooding events throughout the region, particularly in Central Texas.

Flash Flood — Sep 6, 2025

Tropical Storm Lorena's remnants, a late-summer cold front, and an upper-level trough collectively contributed to significant thunderstorm activity across North Texas during the afternoon and evening of September 5th and into the morning of September 6th. Several of these storms generated damaging wind gusts and hail, while frequent cloud-to-ground lightning resulted in multiple residential fires.

Flash Flood — Jul 5, 2025

From the July 4th weekend into the early part of the following week, a weak upper trough lingered over North and Central Texas, triggering several days of scattered showers and thunderstorms. A saturated atmosphere combined with slow storm motions resulted in numerous flash flooding events throughout the region, particularly in Central Texas.

Flash Flood — May 23, 2024

With a highly unstable airmass in place, a meandering front, a dryline, and a shortwave trough all worked together to generate multiple rounds of thunderstorms May 23 and 24. In addition to large hail and damaging winds, multiple tornadoes also occurred along with a few instances of flash flooding. A total of 6 tornadoes occurred in Central and East Texas: 2 EF-1s, 3 EF-0s, and 1 EF-U.
