You can see the current water year plotted on this to show how it compares to historical values. The second graph shows the percentiles of precipitation over the course of the historical water year, spreading out like a cone from the start of the water year (October 1). The top graph is a histogram of water year precipitation totals on the specified date (in blue) as well as the precipitation total for the current water year in red. The visualization consists of two primary graphs both of which show the range of historical values for precipitation. Data from the CDEC website appears to be updated at around 8:30am PST each day. These stations are tracked because they provide important information about the state’s water supply (most of which originates from the Sierra Nevada Mountains). There are three sets of stations that are tracked in the data and these plots: Other California water-related visualizations include reservoir levels in the state as well. I used data for California rainfall totals from the California Department of Water Resources.
This year has been a relatively dry year and wanted to visualize how this year compares with historical levels for this time of year. The data is also archived and is available starting February 8, 2006. the six hour precipitation totals image with mean sea level pressure contours, and 500 mb height wind speed image with 500 mb. It’s winter in California and that means the rainy season (snowy in the mountains). Precipitation Pressure Rain Weather Weather Prediction.
