Mystic Alerts Act Heads to President's Desk After Flood

The Mystic Alerts Act cleared its final congressional hurdle on October 1, 2026, when the U.S. Senate passed the bill unanimously and sent it to President Donald Trump's desk, according to a release from Sen. John Cornyn's office. The measure would let wireless emergency alerts reach mobile phones through satellite links when cell towers go down during disasters — the exact communications failure that investigators say cost lives during the July 2025 Texas Hill Country floods.

Sen. John Cornyn, a Texas Republican, partnered with Sen. Jon Ossoff, a Georgia Democrat, to move the legislation through the Senate, while Rep. August Pfluger of Texas carried it in the House, which passed it unanimously on April 20, 2026, according to the Senate release. "More than 130 people were tragically killed," Sen. Cornyn said of the flooding that inspired the bill, adding that it would "honor the memory of those lost."

Why the bill exists

In the early morning hours of July 4, 2025, floodwaters surged along the Guadalupe River through the Texas Hill Country, overwhelming communities across several counties. Camp Mystic, an all-girls camp in Kerr County, was among the hardest hit. The camp's death toll has been reported differently by different outlets: The Center Square reported that 27 girls drowned, while the senator's office said 28 people died at the camp. The wider toll is also contested — Sen. Cornyn said "more than 130 people" were killed, the outlet put the figure at 139, and the Associated Press reported at least 136 deaths along the river. What is not in dispute is that the alert system failed: many residents never received wireless emergency alerts on their phones, or received them too late to evacuate, according to the outlet, which also reported that county and city officials failed to issue warnings — findings that surfaced at state legislative hearings. The Senate release likewise cited multiple reports of undelivered alerts once cellular infrastructure was damaged.

The investigation is heating up too

Even as the legislation advanced in Washington, the criminal investigation back in Kerr County intensified. Kerr County District Attorney Lucy Wilke asked a court on October 2, 2026, to let her office step aside from the investigation of the camp and to appoint an attorney pro tem, according to the Texian Partisan, which cited reporting by The Kerr County Lead. Wilke pointed to her ties to the Hunt area and a short-staffed office, and she asked that a special prosecutor from the Texas Attorney General's Office take over the case.

Separately, six members of the camp's owning family asked Judge Kirsten Cohoon to block investigators from reviewing data seized under fourteen search warrants obtained the previous month, according to the same briefing, which cited KSAT. The warrants ordered Apple and other companies to turn over messages, photos, location records and other electronic material, and defense lawyers argued they sweep too broadly and reach communications with the family's attorneys.

Affidavits from investigator Brant C. Johnston allege that camp managers treated rising water as a logistics problem, delayed emergency action and lacked a written evacuation plan — conduct that could support charges including manslaughter and criminally negligent homicide, Newsy Today reported. No criminal charges have been filed. The camp has said it will not reopen for the summer of 2026, withdrawing its state license application while investigations and lawsuits continue.

What happens next

From here, the timeline is short: unanimous House passage on April 20, 2026, unanimous Senate passage on October 1, 2026, and then the president's signature, after which the bill becomes law, as KOSA reported. Once signed, the Federal Communications Commission must write the rules that fold satellite delivery into the existing alert system, a process that will determine how quickly carriers actually switch it on.

Participation stays voluntary for carriers. Under the bill, a provider that chooses to send alerts by satellite must notify the FCC of its plans; a provider that declines must tell new and existing subscribers and give them a choice to opt out, according to a summary of the bill's text published by The Center Square. That subscriber-notice requirement is the law's quiet accountability lever: carriers cannot silently sit out.

For readers, the change matters most where towers are thinnest. Flash floods, hurricanes and wildfires routinely destroy the cell sites that carry today's alerts, leaving phones silent exactly when minutes matter. A satellite path would let a warning reach a phone in a dead zone or a storm-struck county even with local networks offline — the scenario the legislation was written to prevent.
