Radar-Based Rainfall Estimates

Radar-based rainfall estimates are based on Doppler weather radar images that are calibrated with actual precipitation measurements to estimate rainfall amounts for each of the 2 x 2 kilometer grid cells in the region. Data are generously provided by the Southwest Florida Water Management District and the St. Johns River Water Management District. Learn more about how the data are collected and aggregated »
