Forecasts for 2, 7 and 90 days

The 2- and 7-day forecasts include predictions of rainfall, air temperature, wind speed, pressure, visibility, relative humidity, dew point, cloud amount and runoff.

2-day forecasts are generated in 3-hour blocks; updated twice a day; at 4km resolution (source: UK Met Office Tropical Africa model).
7-day forecasts are generated in 3-hour blocks; updated every 6 hours; at 20km resolution (source: UK Met Office MOGREPS model).
90-day forecasts are updated every 2 weeks; at 60km resolution using GloSea5 source. It includes probability of rain for any user-defined threshold. Combine with drought indices to determine probability of future drought. The hydrological forecasts make use of the VIC model (Liang et al, 1994).
