Notes
This statement has been prepared based on information available at 10 am on Monday 3 September 2007. Some checks have been made on the data, but it is possible that results will change as new information becomes available.
Normals
are long-term means based on observations from all available years of record,
which vary widely from site to site. They are not shown for sites with less than
30 years of record, as they cannot then be calculated reliably.
The median
is sometimes more representative than the mean
of "normal" rain.
