This year's theme is "60 years of service for your safety and well-being."
The World Meteorological Organization (WMO) and its 189 members and the worldwide meteorological community on Tuesday will commemorate the entry into force, on that date in 1950, of the WMO Convention creating the organization.
In 1951, WMO was designated a specialized agency of the United Nations System.
"I express my gratitude to those working with the Met Office for the role that they play each and everyday in providing invaluable information to boaters, other stakeholders in the marine community as well as to the control tower at the Princess Juliana International Airport.
"The Met Office also plays a very important role during the hurricane season in cooperation with other weather agencies such as the National Hurricane Center out of Miami.
"Hurricanes and other weather related events do not stop at any nations borders. Cooperation between all Met services is necessary in order to save and protect people, their homes, businesses and their community. Congratulations once again on behalf of the people of Sint Maarten and the Island Government," Commissioner William Marlin told the Government Information Service (GIS) on Monday.
