CENTRAL AMERICAN FLASH FLOOD GUIDANCE (CAFFG)

StartDate: 09/2002

In the aftermath of Hurricane Mitch's landfall in Central America in October 1998, the development of a regional Central America Flash Flood Guidance (CAFFG) system was undertaken. The system was designed to produce in real time flash flood relevant information for all seven countries of Central America with a 200 km2 spatial resolution. The CAFFG system uses satellite rainfall estimates and telemetered on-site rain gauge observations, both in real time, to produce for each subcatchment 1-, 3- and 6-hour estimates of mean areal precipitation, 6-hourly estimates of depth-integrated soil moisture, and 1-, 3- and 6-hour flash flood guidance. The information is transmitted to the national forecast agencies to assist with the short term forecast of flash floods.
