Set water level alerts

Get notified about Southend — tick as many as you like, they all share the notify settings below.

You'll be notified when this gauge is rising more than 0.10 m/hr — a sign of rapidly increasing water levels.

Each one is saved as its own alert — pause or remove them individually any time.

Not an emergency service — if in danger call 999. Alerts rely on EA/SEPA/NRW data and are best-efforts. Terms

Flood predictions aren't generated for tidal gauges — their levels are driven by the tide, not by catchment rainfall, so the forecast models would have no skill here.
