Gemini 3.5 Flash-Lite · Sensor & meteorological cross-match

In plain English: Rome is 0% above its 30-day Precipitation baseline (20 vs 22.7). Unusual does not automatically mean unsafe; this is a statistical departure from recent local weather, not an emergency siren.

Gemini may only interpret numbers already on this page. Chart annotations below are computed from the dated series (onset, peak, duration, latest vs baseline). Hypotheses are labeled and are not verified causes.
