Estimated and forecasted 24-hourly rainfall

Data provided by the United States Geological Survey USGS and subject to availability.

NOAA (National Oceanic & Atmospheric Administration ) data provides estimates of actual rainfall based on satellite imagery, corrected with readings from gauging stations of the GTS network.

MM5 (Fifth Generation Mesoscale Model operated by the US Air Force) gives three, 24-hourly forecasts of rainfall for consecutive days. 

The convention used on this web page is: 

MM5 +0 : Forecast for the indicated date,  made on the indicated date
MM5 +1 : Forecast for one day later then the indicated date, made on the indicated date
MM5 +2 : Forecast for two days later then the indicated date, made on the indicated date

Example: 

19-Sep-2001 +0 are the forecasts for 19 September, made on 19 September
19-Sep-2001 +1 are the forecasts for one day later, 20 September, made on 19 September
19-Sep-2001 +2 are the forecasts for two days later, 21 September, made on 19 September

Dates are based on 00:00 GMT until 00:00 GMT
