- Japhet Dissipates
- River Levels Declining
- Localized Flooding Forecast
The Department of Meteorological Services in Zimbabwe recently issued a warning for potential flooding in western and northern Zimbabwe due to heavy rains that may arise from an intense low pressure system that has developed over the Zambezi valley. An African Weather Hazards Assessment (AWHA) bulletin issued by NOAA suggests that this low pressure system may also affect parts of Zambia, Malawi, and northern Mozambique. If heavy rains materialize as forecast, local flooding may occur in some of these areas, especially as there is already high soil moisture in these areas. However, widespread flooding is not expected. The AWHA is issued once a week after a multidisciplinary team of African and American scientists has analyzed current meteorological and hydrological conditions, and their potential impacts.
A Regional Flood Watch will be issued in due course detailing the flooding and impacts that arose from cyclone Japhet, and other earlier flood events that occurred across the SADC region during the 2002/2003 rainfall season.
The significant Weather Developments Bulletin is intended to provide timely highlights of developing weather patterns that might pose a threat to human lives and property. While efforts have been made to ensure accuracy of this report, country specific requirements should be addressed to the National Meteorological Services. The RRSU and FEWSNET produce a Situational Regional Floodwatch during the rainy season.

An analysis of Meteosat satellite imagery, NOAA satellite-derived rainfall estimates, AFWA rainfall forecast models, USGS/FEWS NET water balance and hydrological streamflow models, ground reports, and any other available information is incorporated to estimate ground impacts. USGS/FEWS NET also provides direct input.
