The maximum accumulation is over 24 hours, i.e., from day=D, time=0 to day=D+1,time=0 (step=24). These provisional calculations are provided by the Synoptic Data API Services. Coloring is based on the legend at the bottom-left of the map. Totals are given in units of inches, with trace values being represented as a value of T. Water Year Graph of Snowpack & Precipitation (Current water year and 30-yr average data) Comparison Graph of Snowpack & Precipitation (Current and previous water years, and 30-year average data.) 7-Day Snow Depth Report (Only available for sites with snow depth sensors. For example, runoff at day=D, step=12 will provide runoff accumulated from day=D, time=0 to day=D, time=12. This page displays precipitation totals calculated from weather station data. List-Based Access to SNOTEL Data -Contains the most updated data available. The accumulations in the short forecasts of ERA5-Land (with hourly steps from 01 to 24) are treated the same as those in ERA-Interim or ERA-Interim/Land, i.e., they are accumulated from the beginning of the forecast to the end of the forecast step. more showers with rainfall totals around normal or slightly above. The accumulations in monthly means have units that include " per second".ฤก Please, note that the convention for accumulations used in ERA5-Land differs with that for ERA5. Nonetheless, precipitation accumulations over the week will be below normal due to. N/A For seasonal forecasts, as data only cover 7 months Where t 2 is the 1st day of month after the month of interest, t 1 is 1st day of month before t2, N is number of days in month of interest, SSR t2 is the SSR at t2, and SSR t1= is the SSR at t1.
