Notes

This statement has been prepared based on information available at 9 am on Tuesday 2 January 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 averages 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.
