Forecast details

WPC’s quantitative precipitation forecast: how much rain, or the water in melted snow and ice, it expects to fall over 24 hours, drawn as contours of 0.01 inch and more. It is an amount, not a probability, and not a flood forecast: whether rain floods depends on how fast it falls and on the ground. WPC’s Excessive Rainfall Outlook, in the Flash-flood risk view, is its chance of that. WPC’s rain forecasts.
