Widespread strong winds will spread from the Northern Plains to the Great Lakes today and reach the Central Appalachians, Mid-Atlantic, and Northeast by Thursday, where some blizzard conditions are expected in the Appalachians.

Table C1

Geographical Area Designator A1 A2

(when T1   =   A, B, C, E, F, M, N, R, S, U, V, W)
(excluding ship data)

Instructions for the proper application of the geographical area type designator

1. The designator specified in this table should be used to the greatest extent possible to indicate the geographical area of the data contained within the text of the bulletin or where the geographical designator is needed for addressing purposes.

2. Where the geographical area of the data does not correspond exactly with a designator, the designator for the geographical area most approximating that of the data shall be used. This is important for aviation products where the subject area extents beyond national boundries (i.e. SIGMETS, etc..).

3. When the table does not contain a suitable designator for the geographical area and for METNO and WIFMA messages, the use of XX as the alphabetic designator shall be used.

4. This table is subdivided into two parts: the first part contains geographical designators related to countries or tarritories in each RTH zone of responsibility for collection of observational reports, areas of forecast, and for use in administrative or service messages. The second part contains those designators for vast areas such as areas of analyses, areas of forecast (if appropriate), continents, hemispheres, oceans, etc.


NOTE: The designations employed and the presentation of the material in this table do not imply the expression of any opinion whatsoever on the part of the Secretariat of the World Meteorological Organization concerning the legal status of any country, territory, city or area, or its authorities, or concerning the delimitation of its frontiers or boundaries.
