Each row is one crossing, not one gauge. A gauge that breached more than one band (e.g. both the 6hr Heavy and Extreme levels on the same peak) gets a row per band. Scans the last 48 hours for the highest total in any window of that length, so a peak from earlier today still shows even if the gauge has since eased off. It is the same window the gauge map's own Thresholds panel uses.

Data gaps
info Data gaps
Each gauge is checked for how much data it actually reported over the selected window. This filter hides stations missing more than the chosen share of readings, so the table isn't cluttered with unreliable or offline gauges. Gaps are usually caused by temporary faults at the Environment Agency, Natural Resources Wales or SEPA APIs, not by an absence of rainfall. Choose "Show all" to see every gauge regardless of missing data.

The Share button on the map pages makes a ready-to-post picture of the map, with its title, time, colour key and data credits. Drag and zoom to frame it, then pick wide, square or tall. On the radar, model and radar rainfall maps it can also turn the loop into a short video, played six times over so it runs on in a feed. Post to X straight from it, or use your phone's share menu.
Two new buttons sit at the foot of the map buttons on the radar and model pages. Search finds a town or postcode and drops a pin, or use your location, or press and hold anywhere on the map. Measure draws a line to give the distance and bearing, or choose Diameter to click a centre and an edge and read the radius, diameter and area. Distances can be in km, miles or nautical miles, and points snap to your pin.
A new button under the zoom buttons lets you set a level and show only what meets it, such as rain at or above 30 mm or gusts below a given speed. Or choose Custom colours to give each level its own colour, for example red from 30, amber from 20 and green from 10. A pill at the top of the map says when thresholds are on, and the key shows your levels. It works on weather observations, Radar and Radar Accumulation, and the Model Viewer and Model Multi for rain, wind and gusts, temperature, temperature anomaly, cloud cover and wet-bulb potential temperature.
