No. 764.

ROYAL OBSERVATORY, HONG KONG.

Notice to Mariners.

New Storm Signal Codes, Local and Non-Local, will be introduced at Hong Kong from 1931, March 1.

2. Copies of the Codes are appended to this Notice. They were recommended for general use in the Far East at a Conference of Directors of Far Eastern Weather Ser- vices, held at Hong Kong from April 28 to May 2, 1930.

3. The alterations to the existing Hong Kong Local Storm Signal Code were made to meet the requirements of the Philippine Archipelago, where conditions are different and where no Non-Local Storm Signal Code is used.

4. The new Non-Local Storm Signal Code is an adaptation of the China Seas Storm Signal Code, the alterations being the outcome of 10 years' experience with that code.

DAY SIGNALS.

Meaning.

A depression or typhoon exists which may possibly affect the locality. Strong wind with squalls may possibly occur from the S.W. (S-W). Strong wind with squalls may possibly occur from the S.E. (E-S). Typhoon dangerous but danger to locality not imminent.

Gale expected from the N.W. (W-N).

Gale expected from the S.W. (S-W).

7

Gale expected from the N.E. (N-E).

8

Gale expected from the S.E. (E-S).

9

Gale expected to increase.

10

Wind of typhoon force expected (any direction).

Signal No. 4 will be used in the Philippines, but not at Hong Kong, the information it conveys being given by the Non-Local Signals.

Signals 5 to 8 are not hoisted until it is tolerably certain that a gale (40-45 m.p.h. by the Dines Anemometer) will occur at Hong Kong or Gap Rock, or when a typhoon is sufficiently near to warrant a danger signal, although the occurrence of a gale is by no means certain,

If, with one of signals 5 to 8 hoisted, conditions indicate that the wind will not only increase but attain hurricane force, signal No. 9 may be dispensed with, thus giving the longest possible warning of destructive winds.

Signal No. 10 will be accompanied by three explosive bombs, fired at intervals of 10 seconds at the Water Police Station and repeated at the Harbour Office.
