Flash flood analysis display for the Areal Mean Basin Estimated Rainfall (AMBER) program showing Average Basin Rainfall (ABR) in inches for the 6-hour period ending 1341 UTC on 25 January 1996. ABR is estimated from the Molokai WSR-88D Doppler radar using the algorithm tuned to the tropical drop size distribution. Solid Blue line represents 1-, 3-, and 6-hour Flash Flood Guidance (FFG) values for moderate floods based on local climatology. Colors on ABR curve show flash flood alert values determined by the ratio of ABR to FFG.
