Texas Flash Flood Tragedy

Bill1 Comment

In spite of what some irresponsible newscasters are reporting, along with some political figures, the tragedy of the flash floods in Texas was not due to budget cuts, nor was it due to lack of staffing at The Weather Forecast Office (WFO) for Austin/San Antonio. The cuts were not in place and there were more people on duty than normal at the WFO during the event.

The first notification from the WFO was issued 12 hours in advance of the first warnings. Timely notifications also followed. The flood watch that was issued at 1:18 PM CDT on July 3, 2025, appears below:
