Does appearing on this Wiltshire page mean there is a flood warning?

No. The directory lists permanent Environment Agency monitoring areas and stations associated with Wiltshire. Current warnings are shown separately in the live-status panel near the top of the page.

How many EA monitoring areas are associated with Wiltshire?

This directory snapshot contains 79 designated warning or alert areas associated with Wiltshire. The count describes official monitoring coverage; it is not a county or property risk score.

What do the blue points on the map mean?

Each blue point is an Environment Agency water-level monitoring station. A point is not a reported flood, an active warning or proof that nearby property is at risk.

How should I check a specific property?

Use the official long-term flood-risk service for the address, check current warnings, review several station readings where relevant and obtain professional advice for a purchase, planning or insurance decision.
