How we know

One source: NOAA. Not yet confirmed by a second, independent source.

Our own score for this event is 39 out of 100, at 81 % confidence.

Computed under scoring rules v1. Rows carrying other versions were judged by different rules and are not directly comparable.

Safety Information

During flooding: never walk, swim, or drive through floodwaters. Six inches of moving water can knock you down, and one foot of water can sweep away a vehicle. Move to higher ground if waters rise. After flooding, avoid contact with floodwater which may contain sewage, chemicals, or debris. Follow local emergency service guidance.

Series begins 8 March 2026. Comparisons refer to that period only. Collection gap: 14-26 August 2026.
