Product Description

This CAFFG regional product represents the flash flood threat (FFT) index. The FFT index is the excess amount of rainfall for a three hour period over what is needed to cause bankfull flows (i.e., minor flooding) in small streams draining areas of approximately 70 sqkm. The FFT Forecast product is updated every six hours, beginning at 00:00 UTC (valid between 00:00 and 03:00 UTC). In general, higher FFT index values indicate a greater likelihood that flash flooding will occur or is occurring in the area depicted.

The images shown here are intended to be used as examples of products available to Central America forecasters. Additional products are available at the local government Meteorological and Hydrological Services. Such Services should be contacted for more detailed information and official forecasts.
