How to read thisEach figure is the likely level, with the range from a dry spell to a wet one in brackets. A reservoir is listed when the dry end of that range falls below 30% within 12 weeks. Below that, companies are usually well into their drought plans.
How reliable is it?The projection replays how each reservoir behaved from this date in earlier years; it uses no rain forecast. On the long records it was tested on, the likely figure had about half the error of assuming no change, and it leans cautious. Records under 10 years are marked indicative: they have not been tested.

Rain and temperature: last 30 days and the next two weeks

No freeze-then-thaw and no heatwave in the 16-day forecast. These are the two weather patterns that most often cut supply at short notice.

How to read thisUnder 100% means drier than usual for the time of year. Reservoirs need a run of wet weeks to refill, and rain on dry ground soaks in before it reaches them, so one wet fortnight rarely changes the picture.
How reliable is it?Rain forecasts are useful for about a week and roughly right to two; nothing here looks further. Each area is read at one point, so treat it as a broad indication. The two temperature triggers are rules of thumb, not tested.

One point per area, so a broad indication. Normal is the 1991 to 2020 average for the same days of the year. Freeze then thaw: 2 days with nights at -4°C or below and days no warmer than 2°C, then 7°C or above within 3 days. Heatwave: 3 days in a row at 27°C or above. Both triggers are judgements, not backtested.
