Seasonal rain accumulation
The below plots show the daily rainfall and the total seasonal accumulation of precipitation, compared to the historical average, for our point of interest (shown by the red star in the map below).
Forecast for wind and precipitation
This animation shows the forecast of precipitation (color shading) and horizontal winds at 850 hPa, which is about 1.5 km above sea level. The precipitation is the accumulation over the previous 6-hour period, in millimeters (1 inch = 25 mm), and winds are measured in m/s (1 m/s = 2.2 miles per hour). This is from a single deterministic forecast; the ensemble, probabilistic forecast for the point of interest (marked by the red star on the map) is shown below.
All forecast data is from the Global Ensemble Forecast System (GEFS) of the U.S. National Centers for Environmental Prediction (NCEP). All forecasts use an initial atmospheric state at the time indicated on the plot (note that 00Z is midnight Universal Coordinated Time, which is 1 am in central Africa or 8 pm the previous day in New York [EDT]).
