Featured Tool: Northeast Region Drought Streamflow Probabilities

This application allows the display and query of drought probability. Maximum likelihood logistic regression is used to estimate drought probabilities for selected Northeast region streams. Winter streamflows are used to estimate the chance of hydrologic drought during the summer months (July, August, and September) 5 to 11 months in advance.
