“A thunderstorm produced four inch diameter hail in Round Rock. This storm was part of a complex that caused 700 million dollars in hail damage in Texas. The damage in Austin, Georgetown, and Round Rock was the most impactful from this system and totaled upwards of 600 million dollars in damage across Williamson and Travis counties.

Provenance
Final counts: NCEI Storm Events Database, file vintage c20260527, hail events with recorded magnitude ≥1.00″ and point coordinates within 35 miles of the Austin anchor. NWS records are point and path observations. The absence of a nearby report does NOT prove that no hail fell at this address — it means no observation was logged nearby. A report of nearby hail documents the event; it does not by itself prove damage to a specific structure. Spotted an error? Email the address on our terms page and we correct against the source.
