Storms will continue to bring heavy rain, flooding and strong winds to California and many states across the west. Heavy rain will result in flooding for some areas, and heavy snow will be possible at high elevation locations. By mid-week, these storms may bring heavy snow to the northern Rockies and Intermountain west. Heavy rain and flooding will also impact the central Gulf Coast this week. Read More >

Radar-Derived Precipitation Estimates

 

Radar-derived Precipitation Estimates are a combination of Radar data and rain gauge observations. These estimates may be referred to as MPE values because they are derived by using the Multi-Sensor Precipitation Estimator (MPE) Program. This data may also be referred to as Stage III data, because the MPE process is the third stage of quality control on the radar-derived precipitation amounts. Hourly Radar rainfall estimates are compared to hourly gauge values to produce hourly MPE values.
