1 signal may also be issued when a tropical cyclone is departing Hong Kong but strong winds are still affecting offshore waters. It was fired twice whenever the wind was expected to blow with typhoon force and fired again if possible wh… Also, unlike strong wind signal #3, which is … Doors and windows should be checked to make sure that they can be securely fastened. A number of old signal masts in the New Territories and the outlying islands had to be repaired, and several new signal stations were brought into use.

Attention should be paid to weather bulletins as records show there are three chances in four that No.

Ships with power should move or prepare to move to typhoon buoys or anchorages. Typhoons can cause the tide to rise much higher than normal.

In case you hadn’t noticed, it’s pretty wet out there.While the folks over at the Hong Kong Observatory (HKO) say Typhoon Sarika’s direct threat to Hong Kong is expected to decrease gradually throughout the day, the T3 warning — indicating strong winds — which has been in force since 1:40pm yesterday may be changed to a “Strong Monsoon” signal.If you (like us) aren’t super familiar with what that entails, it means that winds associated with a monsoon are either blowing in excess of 40 kilometres per hour near sea level, or are expected to. People away from home should either return immediately or find a safe place and remain there until the danger has passed. Whereas for easterlies, part of the cold air mass is over the seas and modified by the warmer sea waters, temperature drop is generally less and the air is less dry. The Hong Kong Observatory is planning to raise a strong wind signal No 3 on Friday night, replacing a monsoon signal in a rare move as a tropical cyclone is forming over the South China Sea. In 1935, the signal system was further revised as agreed between the Observatory and the Central Weather Bureau of Manila. dispatched by hong kong observatory at 07:05 hkt on 31.07.2020

Your display name will appear here. From time to time, under the influence of upper air disturbances, cold air from this anticyclone plunges southward through China and brings outbursts of cold air to the south China coastal areas. 3 is issued, all government agencies shut down their operations, schools immediately cease classes, financial markets and most of the private sector close their doors. The No. 7th May 2019 – (Hong Kong) According to Hong Kong Observatory, an upper-air disturbance is bringing showers to Guangdong.

Based on the suggestions by the committee, the typhoon gun, which had been used to warn of a strong gale of wind since 1884, was abolished in 1907. In some cases, it was also followed by gale warnings (i.e. This leads to the formation of a semi-permanent low pressure area near the heart of the continent. The significant reduction of the number of fatalities brought by tropical cyclones to Hong Kong clearly reflects the effectiveness of the tropical cyclone warning system.In 1917, a numbered signal system was implemented for warning wind conditions in the territory. gust up to 111 miles per hour) Windows and doors should be bolted and shuttered and cars parked in sheltered areas. In accordance with legal codes and custom in Hong Kong, once any signal higher than No. With effect from 1 April 2000, signals will no longer be hoisted at the signal stations at With effect from 21 April 2001, signals will no longer be hoisted at the signal station at With effect from 1 January 2002, signals will no longer be hoisted at the signal station at The decommissioning of Hong Kong's last signal station at Cheung Chau marked the end of an era of signal stations. 2 to 4 were not used in Hong Kong while Signal No. 9 or No. If premises are buffeted by hurricane-force winds, all internal doors should be kept tightly shut to lessen the chance of windows or air-conditioning units being blown out or sucked in. The new local code was the first numbered tropical cyclone signal system in Hong Kong, consisting of seven signals (1 to 7)providing a standby signal, gale signals in four directions (N'ly, S'ly, E'ly and W'ly), an increasing gale signal and a hurricane signal. 1 doesn't correspond to any wind strength. 5 to 8). From now on, tropical cyclone and strong monsoon signals will be "issued" or "cancelled" rather than "hoisted" or "lowered". As the population grew after the Second World War, signal stations gradually increased in number across the territory in addition to signal stations at the Hong Kong Observatory Headquarters and outstations at Cheung Chau and Waglan Island. Monsoons are large-scale wind systems caused by differences in the temperatures of land and sea over the seasons.In winter, the continental land mass cools off rapidly, resulting in very low temperatures over central Asia. The Hong Kong Observatory has issued the Strong Monsoon Signal at 10:45am today. (gale: up to 54 miles per hour;

No. During the year, the Marine Department signal station at In 1962, visual signals displayed at 33 signal stations in various parts of Hong Kong. A Black Cross was also hoisted at the same time, superior to other shapes (that is above all the non-local signals), to indicate winds of hurricane force. It was fired once whenever a strong gale of wind was expected. In spring, easterlies take over again and the number of the northeast monsoon in Hong Kong drops quickly.Even though the above analysis is based fully on the statistics of Strong Monsoon Signals and the northeast monsoon cases are not exhaustive, they are indicative guidance on the understanding of the process of strong cold air outbreaks over the South China coastal areas.
Letters and questionnaires were sent to shipping companies, government departments and other organisations to find out whether the majority of people in Hong Kong wanted to change the existing storm warning signals to make them simpler in that increasing signal number would indicate increasing winds.

Gutters and storm drains should be cleared of leaves and rubbish. 1 was effected in 1927. Depending on the time of the season, and the juxtaposition of various weather systems, these surges will arrive in Hong Kong as northerlies, northeasterlies or easterlies.In summer, intense solar heating leads to scorching temperatures over the Asian land masses.
