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.
