ii. To store the digital grid point data received from a WAFC and to process and supply selectively these data to meteorological authorities and other users in the service area in an agreed format.
iii. To prepare upper wind and temperature charts on the basis of the data received and to supply the relevant charts and abbreviated plain-language amendments to users as agreed between the RAFC and the users within its service area.
iv. To notify the relevant WAFC immediately of the contents of and reasons for any amendments it has issued to the forecast received from the WAFC.
