Multi-Sensor Precipitation

Fire Weather Concerns in the Mid-Atlantic and Northeast Today; Record Heat in the Southern U.S.; Tropical Depression Near Guam

Elevated to locally-critical fire weather conditions will continue across portions of southern New England and the Mid-Atlantic today. Record heat is expected in the southern Plains into portions of the Southeast into the weekend. Tropical Depression Kong-Rey has developed near Guam and the Northern Mariana Islands. Impacts include strong winds, hazardous surf, and locally heavy rainfall. 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.
