Graph shows cumulative precipitation threshold for landslides (red line) and the most recent and expected values of 3-day and prior 15-day cumulative precipitation at selected National Weather Service Gages (symbols). The expected values are calculated from recent rainfall combined with the National Weather Service precipitation forecast. Landslides are likely to occur on days when precipitation totals exceed the threshold (plot above or to the right of the red line). Landslides are unlikely to occur when precipitation totals plot below the red line, in the lower left corner of graph.
