Rainfall Map

This map is meant to be an approximate depiction of the areas that have had rain over the 3 hour period ending at 2, 5, 8 and 11, am and pm. The map is created using a network of rain gauges, so no data is available over the water. This data is not quality controlled, and the map may not be accurate, particularly in areas where there are few gauges.
