Rainfall totals for the last 24 hours to 3 days – high resolution map

Data collected using Doppler radar polarimeteric technology are objectively analyzed by complex precipitation algorithms to produce very accurate estimates of accumulated precipitation at each grid point. For your convenience, these high-resolution data are displayed on Google Maps so you can pan and zoom. The Google Map is also clickable to reveal the exact estimate at any given point. Our maps will display on any mobile device, including smartphones and tablets, though you may notice a better visual presentation and optimal performance from a desktop computer.
