What should I record during multi-day rainfall to compare causes safely? The safest answer begins by recording location, trigger and timing before assigning a cause.
What the question is testing
Long wetting duration can saturate materials and reveal slow drainage or storage pathways. The question becomes more useful when it separates what happened first from what was noticed later.
A practical comparison
Record multi-day rainfall, the first affected location and the comparable areas that stayed normal. Repeat the observation only under safe, comparable conditions and note what stayed unchanged.
Limits and next step
Do not remove structural finishes, enter flooded electrical zones or treat sewage-contaminated water as ordinary dampness. Movement, active flooding and energized water demand prompt professional help. Use the connected atlas guide to build a bounded evidence packet and a clear professional handoff when needed.
