# Hypothesis

**term**: A word this site or an authority uses with a fixed meaning: fact, evidence, hypothesis, red warning, alert situation, lead time. [All term nodes](README.md). Also written: hypothesis; hypotheses.

| [11 Nov, 09:41 UTC](../../incidents/2026-11-10-storm-charles/timeline.md#s-1111T0941) | hypothesis | analysis (incident.meteorologist@, hypothesis) on the press's "two centres" (s-1111T0939). Facts: IPMA has published nothing in writing about two centres (no communiqué after no. 2, which speaks of one; its CAP texts do not describe the low). Madeira airport's pressure was lowest at 991 hPa at 06:30… |

| [11 Nov, 08:22 UTC](../../incidents/2026-11-10-storm-charles/timeline.md#s-1111T0822) | fact | Observed at the airports at 08:00. Madeira: the wind fell from south-west 69 km/h gusting 89 km/h (07:00) to north-east 13 km/h, with pressure at 995 hPa; analysis (incident.meteorologist@, hypothesis): the storm's centre passed close to Madeira airport between about 07:30 and 08:00. Lisbon: south-s… |
| [11 Nov, 02:29 UTC](../../incidents/2026-11-10-storm-charles/timeline.md#s-1111T0229) | hypothesis | analysis (incident.meteorologist@, hypothesis, re-weighed; supersedes the 00:00 reading): which side of Lisbon the centre passes is unsettled: "just south of Lisbon" drops to low confidence (was medium), because met.no's 01:19 run veers the wind through south to west with its strongest mean wind (56… |
