Flash Flood Warning until 8:30 PM for Rockwall County, Royse City, Heath

The National Weather Service in Fort Worth issued a Flash Flood Warning for Rockwall County that remained in effect through 8:30 PM CST on March 4, citing heavy rain that had already produced 1–2 inches and warned of an additional 2–4 inches expected. The warning explicitly named Rockwall County and coincided with storm reports affecting Royse City and Heath as the system moved across north central Texas.

The bulletin and consolidated reports identified the primary hazard as street and stream flooding across Rockwall County during the warning window, with local infrastructure at risk from rapid runoff after the recorded rainfall amounts. Emergency responders and county crews in Royse City and Heath faced a narrow window—up to 8:30 PM CST on March 4—to monitor low-lying roads and small tributaries that can rise quickly when an additional 2–4 inches of rain arrive atop the initial 1–2 inches.

Storm observations included a report of quarter-size hail near the Rockwall–Royse City line during the storms, a detail logged in the original consolidated account of the event. That same account contained a truncated safety fragment, quoted exactly as provided: "Residents warned not to drive throu" — a reminder that the consolidated messaging to residents was interrupted in the available report and that full official guidance should be consulted for complete driving and evacuation advisories.

Public health and equity concerns followed from the measured rainfall and flooding threat: with 1–2 inches already fallen and potentially 2–4 more expected, street and stream flooding can interrupt transit, delay ambulance and mobile health visits, and disproportionately impact people who lack personal vehicles or live in flood-prone housing in Rockwall County communities such as Royse City and Heath. Local health providers and care coordinators serving homebound patients would be most affected during the warning window that ran through 8:30 PM CST on March 4.

Key specifics remain to be clarified in official products: the full NWS Fort Worth warning text and issuance time, precise street and stream locations affected, and confirmation of the hail report source near the Rockwall–Royse City line. As the storm moved out of the area after the March 4 warning expiration, county emergency management and NWS Fort Worth remain the authoritative sources for confirmed road closures, damage assessments, and follow-up public-safety guidance for Rockwall County, Royse City, and Heath.
